Emission Control Information To protect the environment in which we all live, Norton motorcycles (UK) ltd has incorporated crankcase emission (1) and exhaust emission (2) control systems in compliance with applicable regulations of the United States Environmental Protection Agency and California Air Resources Board. Additionally, Norton has incorporated an evaporative emission control system (3) in compliance with applicable regulations of the California Air Resources Board on vehicles sold in California only. 





Crankcase Emission Control System: This system eliminates the release of crankcase vapours into the atmosphere. Instead, the vapours are routed through an oil separator to the intake side of the engine. While the engine is operating, the vapours are drawn into combustion chamber, where they are burned along with the fuel and air supplied by the injection system. Exhaust Emission Control System This system reduces the amount of pollutants discharged into the atmosphere by the exhaust of this motorcycle. The fuel and ignition systems of this motorcycle have been carefully designed and constructed to ensure an efficient engine with low exhaust pollutant levels. Evaporative Emission Control System Vapours caused by fuel evaporation in the fuel system are not vented into the atmosphere. Instead, fuel vapours are routed into the running engine to be burned, or stored in a canister when the engine is stopped.

The Clean Air Act, which is the Federal law covering motor vehicle pollution, contains what is commonly referred to as the Act’s “tampering provisions”. “Sec. 203(a) the following acts and the causing thereof are prohibited... (3)(A) for any person to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title prior to its sale and delivery to the ultimate purchaser, or for any manufacturer or dealer knowingly to remove or render inoperative any such device or element of design after such sale and delivery to the ultimate purchaser. (3)(B) for any person engaged in the business of repairing, servicing, selling, leasing, or trading motor vehicles or motor vehicles engines, or who operates a fleet of motor vehicles knowingly to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title following its sale and delivery to the ultimate purchaser...”

4

Note: The phrase “remove or render inoperative any device or element of design” has been generally interpreted as follows:  Tampering does not include the temporary rendering inoperative of devices or elements of design in order to perform maintenance.  Tampering could include:  Maladjustment or vehicle components such that the emissions standards are exceeded.  Use of replacement parts or accessories which adversely affect the performance or durability of the motorcycle.  Addition of components or accessories that result in the vehicle exceeding the standards.  Permanently removing, disconnecting, or rendering inoperative any component or element of design of the emission control systems. WE RECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF FEDERAL LAW, THE VIOLATION OF WHICH IS PUNISHABLE BY CIVIL PENALTIES NOT EXCEEDING $10,000 PER VIOLATION. Tampering With Noise Control System Prohibited Owners are warned that the law may prohibit:  The removal or rendering inoperative by any person other than for purposes of maintenance, repair or replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is use; and  The use of the vehicle after such device or element of design has been removed or rendered inoperative by any person Federal law prohibits the following acts or the causing thereof: (1) The removal or rendering inoperative by any person other than for purposes of maintenance, repair, or replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the vehicle after such device or element of design has been removed or rendered inoperative by any person. Among those acts presumed to constitute tampering are the acts listed below:  Replacement of the original exhaust system or muffler with components not in compliance with federal regulations.  Removal of the muffler(s) or any internal portion of the muffler(s).  Removal of the air box or air box cover.  Modifications to the muffler(s) or intake system by cutting, drilling, or other means if such modifications results in increased noise levels.

Foreword This Manual is designed primarily for use by trained mechanics in a properly equipped shop. However, it contains enough detail and basic information to make it useful to the owner who desires to perform his own basic maintenance, the proper use of tools, and workshop procedures must be understood in order to carry out maintenance and repair satisfactorily. Whenever the owner has insufficient experience or doubts his ability to do the work, all adjustments, maintenance, and repair should be carried out only by qualified mechanics. In order to perform the work efficiently and to avoid costly mistakes, read the text, thoroughly familiarize yourself with the procedures before starting work, and then do the work carefully in a clean area. Whenever special tools or equipment are specified, do not use makeshift tools or equipment. Precision measurements can only be made if the proper instruments are used, and the use of substitute tools may adversely affect safe operation. For the duration of the warranty period, especially, we recommend that all repairs and scheduled maintenance be performed in accordance with the service manual. Any owner maintenance or repair procedure not preformed in accordance with this manual may void the warranty. To get the longest life out of your Motorcycle:   

 

Follow the Periodic Maintenance Chart in the Service Manual. Be alert for problems and non-scheduled maintenance. Use proper tools and genuine Norton Motorcycle parts. Special tools, gauges, and testers that are necessary when servicing Norton motorcycles are introduced by the Special Tool Catalog or Manual. Genuine parts provided as spare parts are listed in the Parts Catalog. Follow the procedures in this manual carefully don`t take shortcuts. Remember to keep complete records of maintenance and repair with dates and any new parts installed.

How to use this Manual In preparing this manual, we divided the product into its major systems. These systems became the manual`s chapters. All information for a particular system from adjustment through disassembly and inspection is located in a single chapter. The Quick Reference Guide shows you all of the products system and assists in locating their chapters. Each chapter in turn has its own comprehensive Table of Contents. The Periodic Maintenance Chart is located in the General Information chapter. The chart gives a time schedule for required maintenance; for example, go to the Periodic Maintenance Chart first. The chart tells you how frequently to change the oil. Next, use the Quick Reference Guide to locate the Engine Lubrication System chapter. Then, use the Table of Contents on the first page of the chapter to find the Change Engine Oil section. 6

Whenever you see these WARNING and CAUTION symbols, heed their instructions! Always follow safe operation and maintenance practices. WARNING: This warning symbol identifies special instructions or procedures which, if not correctly followed, could result in personal injury, or loss of life. CAUTION: This caution symbol identifies special instructions or procedures which, if not strictly observed, could result in damage to or destruction of equipment. This Manual contains four more symbols (in addition to WARNING and CAUTION) which will help you distinguish types of information. Note: This note symbol indicates points of particular interest for more efficient and convenient operation. 

Indicates a procedural step or work to be done. o Indicates a procedural sub-step or how to do the work of the procedural step it follows. It also precedes the text of a NOTE in some cases.  Indicates a conditional step or what action to take based on the results of the test or inspection in the procedural step or sub-step it follows.

In most chapters an exploded view illustration of the system components follows the Table of Contents to show assembly sequence.

Maintenance / Equipment Consult your authorised Norton dealer whenever there is doubt as to the correct or safe operation of this Norton motorcycle. Remember that continued operation of an incorrectly performing motorcycle may aggravate a fault and may also prejudice safety. Ensure all equipment that is required by law is installed and functioning correctly. The removal or alteration of the motorcycle’s lights, silencers, emission or noise control systems can violate the law. Incorrect or improper modification may adversely affect the handling, stability or other aspect of the motorcycle operation, which may result in an accident causing injury or death. If the motorcycle is involved in an accident, collision or fall, it must be taken to an authorised Norton dealer for inspection and repair. Any accident can cause damage to the motorcycle that, if not correctly repaired, may cause a second accident that may result in injury or death. Before Servicing Before starting to service a motorcycle, careful reading of the applicable section is recommended to eliminate unnecessary work. Photographs, diagrams, notes, cautions, warnings, and detailed descriptions have been included wherever necessary. Nevertheless, even a detailed account has limitations; a certain amount of basic knowledge is also required for successful work. Especially note the following:  Dirt: Before removal and disassembly, clean the motorcycle. Any dirt entering the engine or other parts will work as an abrasive and shorten the life of the motorcycle. For the same reason, before installing a new part, clean off any dust or metal fillings.  Battery Ground: Remove the battery ground (-) lead from the battery before performing any disassembly operations on the motorcycle. This Prevents: o The possibility of accidently turning the engine over while partially disassembled. o Sparks at electrical connections which will occur when they are disconnected. o Damage to electrical parts.  Installation, Assembly: Generally, installation or assembly is the reverse of removal or disassembly. But if this Service Manual has installation or assembly procedures, follow them.  Tightening Sequence: Generally, when installing a part with several bolts, nut, or screws, start them all in their holes and tighten them to a snug fit. Then tighten them evenly in a cross pattern. This is to avoid distortion of the part and/or causing gas or oil leakage. Conversely when loosening the bolts, nuts, or screws, first loosen all of them by about a quarter of a turn and then remove them. Where there is a tightening sequence indication in this Service Manual, the bolts, nuts, or screws must be tightened in the order and method indicated.  Torque: When torque values are given in this Service Manual, use them. Either too little or too much torque may lead to serious damage. Use a good quality, reliable torque wrench. 9



Force: Common sense should dictate how much force is necessary in assembly and disassembly. If a part seems especially difficult to remove or install, stop and examine what may be causing the problem. Whenever tapping is necessary, tap lightly using a rubber, wooden or plastic-faced mallet. Use an impact driver for screws (particularly for the removal of screws held by a locking agent) in order to avoid damaging the screw heads.  Edges: Watch for sharp edges, especially during major engine disassembly and assembly. Protect your hands with gloves or a piece of thick cloth when lifting the engine or turning it over.  High-Flash Point Solvent: A high-flash point solvent is recommended to reduce fire danger. A commercial solvent commonly available in the UK is Silkolene (generic name). Always follow manufacturer and container directions regarding the use of any solvent.  Gasket, O-Ring: Do not reuse a gasket or O-ring once it has been in service. The mating surfaces around the gasket should be free of foreign matter and perfectly smooth to avoid oil or compression leaks.  Liquid Gasket, Non-Permanent Locking Agent: Follow manufacturer’s directions for cleaning and preparing surfaces where these compounds will be used. Apply sparingly. Excessive amounts may block engine oil passages and cause serious damage. An example of a non-permanent locking agent commonly available in the UK is Threebond.  Press: A part installed using a press or driver, such as a wheel bearing (hub bearing), should first be coated with oil on its outer or inner circumference so that it will go into place smoothly.  Ball Bearing, Needle Bearing: Do not remove a ball bearing or a needle bearing unless it is absolutely necessary. Replace any ball or needle bearings that were removed with new ones, as removal generally damages bearings. Install bearings with the marked side facing out applying pressure evenly with a suitable driver. Only press on the race that forms the press fit with the base component to avoid damaging the bearings. This prevents severe stress on the balls or needles and races, and prevents races and balls or needles from being dented. Press a ball bearing until it stops at the stop in the hole or on the shaft.  Oil Seal and Grease Seal: Replace any oil or grease seals that were removed with new ones, as removal generally damages seals. When pressing in a seal which has manufacturer’s marks, press it in with the marks facing out. Seals should be pressed into place using a suitable driver, which contacts evenly with the side of seal, until the face of the seal is even with the end of the hole. Before a shaft passes through a seal, apply a little high temperature grease on the lips to reduce rubber to metal friction.  Circlip, Retaining Ring: Replace any circlips and retaining rings that were removed with new ones, as removal weakens and deforms them. When installing circlips and retaining rings, take care to compress or expand them only enough to install them and no more.  Cotter Pin: Replace any cotter pins that were removed with new ones, as removal deforms and breaks them.  Lubrication: Engine wear is generally at its maximum while the engine is warming up and before all the rubbing surfaces have an adequate lubricative film. During assembly, oil or grease (whichever is more suitable) should be applied to any rubbing surface which has lost its lubricative film. Old grease and dirty oil should be cleaned off. Deteriorated grease has lost its lubricative quality and 10



may contain abrasive foreign particles. Don’t use just any oil or grease. Some oils and greases in particular should be used only in certain applications and may be harmful if used in an application and may be harmful if used in an application for which they are not intended. This manual makes reference to molybdenum disulfide grease (MoS2) in the assembly of certain engine and chassis parts. Always check manufacturer recommendations before using such special lubricants. Electrical Wires: All the electrical wires are either single-colour or two-colour and, with only a few exceptions, must be connected to wires of the same colour. On any of the two-colour wires there is a greater amount of one colour and a lesser amount of a second colour, so a two-colour wire is identified by first the primary colour and then the secondary colour. For example, a red wire with thin yellow strips is referred to as a “red/yellow” wire; it would be a “yellow/red” wire if the colours were reversed to make red the main colour. Yellow

Replacement Parts: When there is a replacement instruction, replace these parts with new ones every time they are removed. These replacement parts will be damaged or lose their original function once removed.  Inspection: When parts have been disassembled, visually inspect these parts for the following conditions or other damage. If there is any doubt as to the condition of them, replace them with new ones. Abrasion Crack Hardening Warp Bent Dent Scratch Wear Colour Change Deterioration Seizure  Specifications: Specification terms are defined as follows: “Standards” show dimensions or performances which brand-new parts or systems have. “Service Limits” indicate the usable limits. If the measurement shows excessive wear or deteriorated performance, replace the damaged parts  References to the left-hand or right-hand side given in this manual are made when viewing the motorcycle from the rear.  Operations covered in this manual do not always include references to testing the motorcycle after repair. It is essential that work is inspected and tested after completion and if necessary a road test of the motorcycle is carried out particularly where safety related items are concerned. 11

Throttle Specification Item Throttle Grip Free Play Idling Speed Make, Type Air Cleaner Element Oil Grade Viscosity

Standard 2~3mm 1200 ± 100 (rpm) Jenvey, Norton Commando SE or SF Class SAE30

Throttle Grip and Cables If the throttle grip has excessive free play due to cable stretch or maladjustment, there will be a delay in throttle response. Also, the throttle butterfly may not open fully at full throttle. On the other hand, if the throttle grip has no play, the throttle will be hard to control, and the idle speed will be erratic. Check the throttle grip play periodically in accordance with the Periodic Maintenance Chart, and adjust the play if necessary. Grip Free Play Inspection  Check throttle grip free play[A] by lightly turning the throttle grip back and forth  If free play is improper, adjust the throttle cable  Throttle Grip Free Play Standard:

A

2 ~ 3mm

Grip Free Play Adjustment  Loosen the locknut and screw the throttle cable adjuster on the rear cable (no. 1) so there is approximately 2-3mm free play at the throttle grip. Adjust the front cable (no. 2) until there is slight tension on the front cable.  Tighten the locknuts against the cable adjusters.  Check that the throttle cam stops against the idle adjusting screw with the throttle grip closed.  Turn the handlebars from side to side while idling the engine.  If idle speed varies, the cable may be poorly routed or damaged. Warning: Operation with an improperly adjusted, incorrectly routed, or damaged cable could result in an unsafe riding condition. Throttle Cable Removal  Remove: Fuel Tank (see this chapter)  Take off the adjuster nuts [A] at the throttle body.

32

B

A

Warning: Operation with an incorrectly routed or improperly adjusted cable could result in an unsafe riding condition. Throttle Cable Lubrication and Inspection  Whenever the Cables are removed, and in accordance with the Periodic Maintenance Chart, lubricate the throttle cables (see General Lubrication in the Appendix).  Apply a thin coating of grease to the cable upper ends.  Use a pressure cable luber to lubricate the cables  With the cables disconnected at both ends, the cable should move freely in the cable housing.

33

Throttle Body A dirty or damaged air cleaner can alter the fuel air ratio. Idle speed Adjustment  Start the engine and let it warm up thoroughly.  With the engine idling, turn the handlebar to each side. If the handlebar movement changes idle speed, the throttle cable may be incorrectly routed, or it may be damaged.  Turn the adjuster screw [A] to obtain the slowest smooth idle speed.  Check idle speed. If the idle speed is out of the specified range, adjust it.

A

Idle speed standard: 1200 ± 100 (rpm) 

Open and close the throttle a few times to make sure that the idle speed does not change. Readjust if necessary.

Warning: Operation with an incorrectly routed or improperly adjusted cable could result in an unsafe riding condition. To avoid a serious burn, never touch a hot engine or an exhaust pipe during idle adjustment. Throttle body Removal Warning: Gasoline is extremely flammable and can be explosive under certain conditions. Turn the ignition switch OFF. Do not smoke. Make sure the area is well ventilated and free from any source of flame or sparks; this includes any appliance with a pilot light. 

Oil Level Inspection  Situate the motorcycle so that it is perpendicular to the ground.  If the oil has just been changed, start the engine and run it for several minutes at idle speed. This fills the oil filter with oil. Caution: Racing the engine before the oil reaches every part can cause engine seizure.  



  



Stop the engine and leave it for more than 1 minute for all the oil to drain down. If the motorcycle has just been ridden, run the engine for about 20 seconds at idle speed. Stop the engine and leave it for more than one minute. Check the engine oil by removing the oil filler [A], clean the dip stick with a cloth fully reinsert the plug then remove it again and check the level on the dip stick. The oil level should be in the middle of the two markings. If the oil level is difficult to check, rock the motorcycle both side-to-side, and front-to-rear. If the oil level is too high, remove the excess oil through the filler opening, using a syringe or some other suitable device. If the oil level is too low, add the correct amount of oil through the oil filler opening. Use the same type and make of oil that is already in the engine.

A

Min

Max

Note: If the engine oil type and make are unknown, use any brand of the specified oil to top off the level rather than running the engine with the oil level low. Then at your earliest convenience, change the oil completely. Oil Draining Warning: To avoid burns, do not remove the radiator cap or try to change the coolant when the engine is still hot. Wait until it cools down. Oil on tires will make them slippery and can cause an accident and injury. Immediately wash away any coolant that spills of the frame, engine, or wheels. Since oil is harmful to the human body, do not use for drinking. 

Place a container under the drain plug [A] at the bottom of the sump, remove oil filler cap and then remove the drain plug.

A

49



Place a tray under the bottom radiator hoses [A], remove the bottom banjo bolt [B] and drain the oil from the oil tank hose.

Oil Filling  Tighten the drain plug. Torque – Oil sump drain Plug 20Nm 

Fill the oil tank with 2.5L of oil and tighten the filler cap. Run the engine at idle for 2 minutes in a well ventilated area. Allow the motorcycle to stand for 2 minutes.



Check the oil level as described in (Oil Level Inspection) top up if necessary.

A B

Note: Pour in the oil slowly so that the air in the engine and oil cooler can escape. Caution: Do not add more oil above the full mark. Oil Pump A

Oil Pump Removal  Drain the oil (see Oil Draining)  Remove Oil Pump hoses [A]



Remove Oil Pump retainer bolts [A]



Remove the oil pump from the engine and balance shaft taking care that the drive dowel pin [A] remains in the oil pump drive shaft.

 Remove the Oil Cooler [C] Oil Cooler Installation  Run the hoses and leads according to the Cable, Wire, and Hoses Routing section in the General Information chapter.

Oil Cooler Inspection  Check the Oil Cooler core.  If there are obstructions to air flow, remove them.  If the corrugated fins [A] are deformed, carefully straighten them.  If the air passages of the Oil Cooler core are blocked more than 20% by unremovable obstructions or irreparably deformed fins, replace the Oil Cooler with a new one.

A

Oil Cooler Cleaning  Remove the Oil Cooler (see Oil Cooler remover). Caution: When cleaning the Oil Cooler with steam cleaner, be careful of the following to prevent Oil Cooler damage. Keep the steam gun [A] away more than 0.5m [B] from the Oil Cooler core [C]. Hold the steam gun perpendicular to the core surface. Run the steam gun following the core fin direction [D].

B

Valve seating surface Width Width: Exhaust: 1.5mm Inlet: 1.5mm

  

If the seat width is not within the specified range, repair the valve seat. Measure the outside diameter [B] of the seating pattern on the valve seat. If the outside diameter of the valve seating pattern is too large or too small, repair the valve seat.

Valve seating surface outside diameter Exhaust: 35.5mm Inlet: 43mm Valve Seat Repair (Valve Lapping)  Using the valve seat cutters, repair the valve seat. Valve seat cutters: 87

Valve seat cutting angle inlet: Initial 45˚ then 35˚ (VAI-A19038) then relief 75˚ (VSI-A13600) Valve seat cutting angle exhaust: Initial 45˚ then 29˚ (VSI-A18658) then relief 55˚ (VSI-A13600) 

If the manufacturer’s instructions are not available, use the following procedure.

Seat Cutter Operating Care:  This valve seat cutter is developed to grind the valve for repair. Therefore the cutter must not be used for other purpose than seat repair.  Do not drop or shock the valve seat cutter, or the diamond particles may fall off.  Do not fail to apply engine oil to apply engine oil to the valve seat cutter before grinding the seat surface. Also wash off the ground particles sticking to the cutter with washing oil. Caution: Do not use a wire brush to remove the metal particles from the cutter. It will take off the diamond particles. 

Setting the valve seat cutter holder in position, operate the cutter in one hand. Do not apply too much force to the diamond portion.

Note: Prior to grinding, apply engine oil to the cutter and during the operation, wash off any ground particles sticking to the cutter with washing oil. 

After use, wash it with washing oil and apply thin layer of engine oil before storing.

Operating Procedures:  Clean the seat area carefully.  Coat the seat with machinist’s dye.  Fit a 45˚ cutter into the holder and slide it into the valve guide.  Press down lightly on the handle and turn it right and left. Grind the seating surface only until it is smooth. Caution: Do not grind the seat too much. Over grinding will reduce valve clearance by sinking the valve into the head. If the valve sinks too far into the head, it will be impossible to adjust the clearance, and the cylinder head must be replaced.     

Measure the outside diameter of the seating surface with a vernier caliper. If the outside diameter of the surface is too small, repeat the 45˚ grinding until the diameter is within the specified range. If the outside diameter of the seating surface is too large, make the 35˚ (inlet)/29˚ (exhaust) grinding described below. If the outside diameter of the seating surface is within the specified range, measure the seat width as described below. Grind the seat at a 35˚ (inlet)/29˚ (exhaust) angle until the seat O.D. is within the specified range. 88

 

To make the 35˚ (inlet)/29˚ (exhaust) grind fit a 35˚ (inlet)/29˚ (exhaust) cutter into the holder, and slide it into the valve guide. Turn the holder one turn at a time while pressing down very lightly. Check the seat after each turn.

Caution: The 35˚ (inlet)/29˚ (exhaust) cutter removes material very quickly. Check the seat outside diameter frequently to prevent over grinding.                

After making the 35˚ (inlet)/29˚ (exhaust) grind, return to the seat O.D. measurement step above. To measure the seat width, use a vernier caliper to measure the width of the 45˚ angle portion of the seat at several places around the seat. If the seat width is too narrow, repeat the 45˚ grind until the seat is slightly too wide, and then return to the seat O.D. measurement step above. If the seat width is within the specified range, lap the valve to seat as described below. Grind the seat at a 75˚ (inlet)/55˚ (exhaust) angle until the seat width is within the specified range. To make the 75˚ (inlet)/55˚ (exhaust) grind, fit 75˚ (inlet)/55˚ (exhaust) cutter into the holder, and slide it into the valve guide. Turn the holder, while pressing down lightly. After making the 75˚ (inlet)/55˚ (exhaust) grind, return to the seat measurement step above. Lap the valve to the seat, using a lapper once the seat width and O.D. are within the ranges specified above. Put a little coarse grinding compound on the face of the valve in a number of places around the valve head. Spin the valve against the seat until the grinding compound produces a smooth, matched surface on both the seat and the valve. Repeat the process with a fine grinding compound. The seating area should be marked about in the middle of the valve face. If the seat is not in the right place on the valve, check to be sure the valve is the correct part. If the valve is correct, the valve may have been refaced too much; replace the valve. Be sure to remove all grinding compound before assembly. When the engine is assembled, be sure to adjust the valve clearance (see Valve Clearance Adjustment).

Cylinder, Piston Removal  Remove: o Cylinder Head (see Cylinder Head Removal).  Slacken off cylinder bolts by a quarter of a turn back from twenty to sixteen.  Remove cylinder bolts back from twenty to sixteen.

90

  

Tap lightly up the cylinder head with a plastic mallet to separate from crankcase. When the cylinder is lose, remove in one clean swift movement upwards. If the cylinder becomes jammed it will be because the lifters have dropped down as the cylinder has been pulled up. Settle the cylinder back down, and then remove in one clean swift movement upwards.



Remove the cylinder base gasket.



Immediately insert a clean cloth around the piston to prevent parts or dirt from falling into the case.



Remove the snap ring from one side of each piston pin hole. Caution: Do not reuse snap rings as removal weakens and deforms them. They could fall out and score the cylinder wall. 

Push out the piston pin and remove the piston. 91

 

Carefully spread the ring opening with your thumbs and then push up on the opposite side of the piston ring to remove it. Remove the three – piece oil ring with your thumbs in the same manner.

Cylinder, Piston Installation Note: The oil ring rails have no “top” or “bottom”

    

Install the oil ring expander in the bottom piston ring A groove so the ends butt together. Install the oil ring steel rails, one above the expander B and one below it. Spread the rail with your thumbs, but only enough to fit the rail over the piston. Release the rail into the bottom piston ring groove. With the marked side facing up, install the second ring [A] and top ring [B] in that order.

Note: If a new piston is used, check piston to cylinder clearance (see Piston/Cylinder Clearance), and use new piston rings. 



The right hand piston has an R marked on the underside and the left hand has an L marked on the underside. The dots [A] should always be on the inside on top of the cylinder.

A

Measure the piston diameter at the point shown with a micrometer. Piston Diameter: Standard: 87.900 to 87.925 Service Limit: 87.750

   

If the piston diameter is less than the service limit, replace it. Install the pistons onto the con-rods using new snap rings. Install a new base gasket. Set the crank so that piston No. 1 is at TDC.

Note: Ensure ring gaps at 180 degrees apart. 

Slide the barrels over the barrel bolts. 92



  

Simultaneously lower the barrel whilst sliding the pistons into the barrel, use a front to back rocking motion whilst holding the rings in with your thumb and four fingers to slide the pistons rings into the barrel. Tighten the cylinder bolts by hand. Install the cylinder head (see this chapter). Tighten head and barrel bolts in sequence from one to twenty to torques detailed below.

Torque: Barrel bolts – 25Nm Torque: Head Bots – 25Nm / 54Nm

Note: Whenever the piston or cylinder has been replaced with a new one or honed, the motorcycle must be broken in the same as with a new machine.

93

Piston/Cylinder Clearance  Subtract the piston diameter from the cylinder inside diameter to get the piston/cylinder clearance. Piston/Cylinder Clearance Standard: 0.105 to 0.070   

If the piston/cylinder clearance is less than the specified range, use a smaller piston or increase the cylinder inside diameter by honing. If the piston/cylinder clearance is greater than the specified range, use a larger piston or bore the cylinder to the next larger oversize. If only a piston is replaced, the clearance may exceed the standard slightly. But it must not be less than the minimum in order to avoid piston seizure.

Cylinder Boring and Honing  Before boring a cylinder, first measure the exact diameter of the oversize piston, and then, according to the standard clearance in the Specifications, determine the re-bore diameter. However, if the amount or boring necessary would make the inside diameter greater than 1.0mm, the block must be replaced.  Cylinder inside diameter must not vary more than 0.01mm at any point.  In the case of a re-bored cylinder and oversize pistons, the service limit for the cylinder is the diameter that the cylinder was bored to plus 0.1mm and the service limit for the piston is oversize piston original diameter minus 0.15mm. If the exact figure for the rebored diameter is unknown, it can be roughly determined by measuring the diameter at the base of the cylinder. Piston Ring and Ring Groove Wear  Check for uneven groove wear by inspecting the ring seating.  The rings should fit perfectly parallel to groove surfaces. If not, the piston must be replaced.  With the piston rings [A] in their grooves, make several measurements with a thickness gauge to determine piston ring/groove clearance.

A

Piston Ring/Groove Clearance Standard Service Limit Top: 0.020-0.050 0.150 Second: 0.020-0.060 0.160 B

Piston Ring End Gap Measurement  Place the piston ring inside the cylinder, using the piston to locate the ring squarely in place. 94



Set it close to the top of the cylinder, where cylinder wear is low. Measure the gap [B] between the ends of the ring with a thickness gauge. Piston Ring End Gap Standard Top 0.15-0.35 Second 0.35-0.55 Oil 0.20-0.70

Clutch Lever and Hose Clutch Lever and Adjustment 106



Pull the lever forward and twist the adjuster [A] to move the lever forwards and backwards.

Clutch Fluid Warning: When working the clutch, observe the precautions listed below.

     

 

Never reuse old clutch fluid. Do not use fluid from a container that has been left unsealed or that has been open for a long time. A Do not mix two types and brands of fluid for use in the clutch. It may cause the rubber brake parts to deteriorate. Don’t leave the reservoir cap [A] off for any length of time to avoid moisture contamination of the fluid. Don’t change the fluid in the rain or when a strong wind is blowing. Except for internal clutch parts, use only clutch fluid, isopropyl alcohol, or ethyl alcohol for cleaning clutch parts. Do not use any other fluid for cleaning these parts. Gasoline, engine oil, or any other petroleum distillate will cause deterioration of the rubber parts. Oil spilled on any part will be difficult to wash off completely and will eventually deteriorate the rubber used in the clutch. Clutch fluid quickly ruins painted surfaces; any spilled fluid should be completely washed away immediately. If any of the clutch line fittings or bleed valve is open at any time, the AIRMUST BE BLED FROM THE CLUTCH.

Clutch Fluid Recommendation Recommended fluids are given below. If none of the recommended fluids are available, use extra heavy-duty brake fluid only from a container marked D.O.T. 4. Note: Clutch fluid of D.O.T. 4 is installed in the clutch system when shipped. Recommended Clutch Fluid Type D.O.T. 4 Brand: Fuchs Silkolene Spec. FMVSS 116 D.O.T. 4, D.O.T. 3, ISO 4925 AND SAE J 1703, (or above)

Clutch Fluid Level Inspection In accordance with the Periodic Maintenance Chart, inspect the clutch fluid level in the clutch fluid reservoirs. 107



A

Check the clutch fluid level in the reservoir.

B

Note: Hold the reservoir horizontal when checking clutch fluid level.

Warning: Change the fluid in the clutch line completely if the fluid must be refilled but the type and brand of the fluid that is in the reservoir are unidentified  

Check the fluid in the clutch reservoir [A] is above the lower level line [B]. If the fluid level is lower than the lower level line, fill the reservoir to the upper level line [C] in the reservoir with the same type and brand of the fluid that already is in the reservoir.

C A B

Clutch Fluid Changing         



A

Remove the reservoir cap and the rubber cap on the bleed valve. Attach a clear plastic hose to the bleed valve on the slave, and run the other end of the hose into a container. Fill the reservoir with new clutch fluid. Change the clutch fluid as follows. Open the bleed valve [A]. Apply the clutch level and hold it [B]. Close the bleed valve [A]. Release the clutch lever [B]. If the fluid in the reservoir runs completely out at any time during fluid changing, air will enter the line, and the system must be bled. Repeat this operation until fresh clutch fluid comes out into the plastic hose or the colour of the fluid changes.

Warning: Do not mix brands of fluid. Change the clutch fluid B in the clutch line completely if the clutch fluid must be refilled but the type and brand of the clutch fluid that is already in the reservoir are unidentified. Torque – Bleed Valve: 7 Nm 

Apply the clutch lever forcefully for a few seconds, and check for fluid leakage around the fittings. 108

Warning: If the clutch level or pedal has a soft or “spongy feeling” when it is applied, there might be air in the clutch line or the clutch line may be defective. Since it is dangerous to operate the motorcycle under such conditions, bleed the air from the brake line immediately.

Clutch Line Air Bleeding   

 

      

Bleed the air line whenever clutch parts are replaced or B reassembled. Remove the reservoir cap and fill the reservoir with new clutch fluid. Slowly pump the clutch lever several times until no air bubbles can be seen rising up through the fluid from the hose at the bottom of the reservoir. This bleeds the air from the master cylinder and the brake line. Tap the brake hose lightly going from the slave cylinder to the reservoir side and bleed the air off at the reservoir. Attach a clear plastic hose to the bleed valve on the slave cylinder, and run the other end of the hose into a container. Bleed the brake line and the caliper as follows. Hold the clutch lever applied [A]. Quickly open and close the valve [B]. Release the clutch lever [A]. A The fluid level must be checked several times during bleeding operation and replenished as necessary. If the fluid in the reservoir runs completely out any time during bleeding, the bleeding operation must be done over again from the beginning since air will have entered the line. If the brake lever or pedal action still feels soft or “spongy”, tap the clutch hose from bottom to top and air will rise up to the top part of the hose. Slowly pump the clutch in the same manner as above Torque - Bleed Valve: 7 Nm Torque - Reservoir Cap Screws (integral reservoir only): 1.5Nm



Apply the clutch lever forcefully for a few seconds, and check for fluid leakage around the fittings.

Friction and Steel Plate Damage, Wear Inspection  Visually inspect the friction and steel plates for signs of seizure, overheating (discoloration), or uneven wear.  Measure the thickness of the friction plates at several points.  If any plates show signs of damage, or if they have worn past the service limit, replace them with new ones. Friction Plate Thickness Standard: 2.9 mm ~ 3.1 mm Service Limit: 2.75 mm Friction and steel Plate Warp Inspection  Place each friction plate or steel plate on a surface plate, and measure the gap between the surface plate and each friction plate or steel plate with a thickness gauge. The gap is the amount of friction or steel plate warp.  If any plate is warped over the service limit, replace it with a new one. Friction and Steel plate Warp Standard: 0.2 mm or less Service Limit: 0.3 mm

116

Cutch Spring Free Length Measurement  Measure the free length of the clutch springs.  If any spring is shorter than the service limit, it must be replaced. Clutch Spring Free Length Standard: 54 mm Service Limit: 52.75 mm Clutch Housing Finger Damage  Visually inspect the clutch housing fingers [A] where the friction plate tangs hit them.  If they are badly worn or if there are groove cuts where the tangs hit, replace the housing. Also, replace the friction plates if their tangs are damaged.

Engine Oil and Oil Filter Warning: Motorcycle operation with Insufficient, deteriorated or contaminated engine oil will cause accelerated wear and may result in engine or transmission seizure, accident, and injury. Engine Oil Level Inspection  Situate the motorcycle so that it is perpendicular to the ground.  If the oil has just been changed, start the engine and run it for several minutes at idle speed. This fills the oil filter with oil. Caution: Racing the engine before the oil reaches every part can cause engine seizure.  



  



Stop the engine and leave it for more than 1 minute for all the oil to drain down. If the motorcycle has just been ridden, run the engine for about 20 seconds at idle speed. Stop the engine and leave it for more than one minute. Check the engine oil by removing the oil filler, clean the dip stick with a cloth fully reinsert the plug then remove it again and check the level on the dip stick. The oil level should be in the middle of the two markings. If the oil level is difficult to check, rock the motorcycle both side-to-side, and front-to-rear. If the oil level is too high, remove the excess oil through the filler opening, using a syringe or some other suitable device. If the oil level is too low, add the correct amount of oil through the oil filler opening. Use the same type and make of oil that is already in the engine.

Note: If the engine oil type and make are unknown, use any brand of the specified oil to top off the level rather than running the engine with the oil level low. Then at your earliest convenience, change the oil completely. Engine Oil Draining Warning: To avoid burns, do not remove the radiator hose or try to change the oil when the engine is still hot. Wait until it cools down. Oil on tires will make them slippery and can cause an 133

accident and injury. Immediately wash away any oil that spills of the frame, engine, or wheels. Since oil is harmful to the human body, do not use for drinking. 

Place a container under the drain plug [A] at the bottom of the sump, remove oil filler cap and then remove the drain plug. It is not necessary to remove the primary or secondary exhaust sections, but does make access easier. A



Place a tray under the bottom radiator hoses [A], remove the bottom banjo bolt [B] and drain the oil from the oil tank hose.

A

Engine Oil Filling  Tighten the drain plug. Torque – Oil sump drain Plug: 20Nm 



Fill the oil tank with 2.5L of oil and tighten the filler cap. Run the engine at idle for 2 minutes in a well ventilated area. Allow the motorcycle to stand for 2 minutes. Check the oil level as described in (Oil Level Inspection) top up if necessary.

Note: Pour in the oil slowly so that the air in the engine and radiator can escape. Caution: Do not add more oil above the full mark. Engine Oil Filter Change  Drain Engine Oil  Remove oil filter cover bolts.  Remove oil filter cover.  Remove oil filter.

   

Replace the filter element with a new one. Apply oil to the mounting surfaces and oil filter. Install the oil filter. Install oil filter cover and bolts 134

Torque – filter cover bolts: 6Nm 

Pour in the specified type and amount of oil.

Gearbox Oil Draining Warning: To avoid burns, do not change the oil when the engine is still hot. Wait until it cools down. Oil on tires will make them slippery and can cause an accident and injury. Immediately wash away any oil that spills of the frame, engine, or wheels. Since oil is harmful to the human body, do not use for drinking. 



A

Place a container under the drain plug [A] at the bottom of the gearbox, remove oil filler cap and then remove the drain plug. Allow oil to drain fully.

Gearbox Oil Filling  Tighten the drain plug. Torque – Gear Box Oil Drain Plug: 20Nm 

Fill the gearbox with 1.2L of oil and tighten the filler cap [A].

A

Torque – Gear Box Filler Cap: 20 Nm 

Run the engine at idle for 2 minutes in a well ventilated area.

Note: Pour in the oil slowly so that the air in the engine and radiator can escape. Caution: Do not add more oil above the full mark. Relief Valve Opening Pressure Measurement Note: Measure the oil pressure before the engine is warmed up if you want to test relief valve opening pressure. 

Remove oil passage plug [A] on the oil pump and replace with double banjo bolt and oil pressure gauge adapter.

A

Special Tools – Oil Pressure Gauge Adapter and Oil 135

Pressure Gauge. 

Start the engine, and read the maximum oil pressure while running the engine at various speeds. A normal relief valve keeps the maximum oil pressure between the specified values. Relief Valve Opening Pressure Standard: 300~400 kPa

    

If the reading is much higher than the standard, the relief valve is stuck in its closed position. If the reading is much lower than the standard, the relief valve may be stuck open, or there may be other damage (e.g. crank oil seal damage, oil pump damage) in the lubrication system. Stop the engine. Remove the oil pressure gauge and adapter. Install the oil banjo bolt. Torque – Oil Pump Banjo Bolt: 35Nm

Oil Pressure Measurement Oil Pressure Measurement Note: Measure the oil pressure after the engine is warmed up. 

Attach the oil pressure gauge and adapters to the plug hole (see Relief Valve Opening Pressure Measurement).

Warning: You could receive burns from hot engine oil draining through the oil passage when the plug is removed. Special Tools – Oil Pressure Gauge Adapter and Oil Pressure Gauge. Oil Pressure Standard: 150kPa     

If the oil pressure is much lower than the standard, check the oil pump, relief valve, and/or crankshaft and balance shaft oil seal immediately. If they are not at fault, inspect the rest of the lubrication system. Stop the engine. Remove the oil pressure gauge and adapter. Install the oil pump banjo plug.

136

Oil Pump Oil Pump Removal  Drain the engine oil.  Remove two Oil Banjo bolts.  Remove three outer oil pump retainer bolts.



Taking note of the O-ring and dowel positions remove the oil pump.

A

Oil Pump Installation  Install the oil drive dowel, location dowels and O-rings (use a little grease to hold in place if required.  Fill the pump with engine oil [A] for initial lubrication.  Align the oil pump drive dowel with the balance shaft female drive cut out.  Install the oil Pump and three location bolts. Torque - Oil pump bolts: 12Nm Oil Pump inspection  Disassemble the oil pump (see this chapter).  Visually inspect the oil pump body, outer and inner rotors, and covers. 137



If there is any damage or uneven wear, replace the rotors or the oil pump assembly.

Relief Valve Inspection  Disassemble the oil pump (see this chapter).  Remove the relief valve [A].  Check to see if the piston moves freely when pushing it with a wooden or soft rod, and see if it comes back to its seat by the valve spring pressure.  If any rough spots are found during above inspection, wash the valve clean with a high-flash point solvent and blow out any foreign particles that may be in the valve with compressed air. Warning: Clean the parts in a well-ventilated are, and take care that there are no sparks or flame anywhere near the working area. Because of the danger of highly flammable liquids, do not use gasoline or low-flash point solvents. 

If cleaning dose not solve the problem, replace the relief valve as an assembly. The relief valve is precision made with no allowance for replacement of individual parts.

Oil Pipe Oil Pipe Removal  Remove:  Fuel Tank (see Fuel System chapter)  Remove Battery and Battery Tray (see Electrical System chapter)  Cut double eared clip off and remove oil pump banjo, remove oil tank to oil pump hose.

Ball and Needle Bearing Replacement Caution: Do not remove the ball or needle bearings unless it is necessary. Removal may damage them.  Using a press or puller, remove the ball and/or needle bearings. Note: In the absence of the above mentioned tools, satisfactory results may be obtained by heating the case to approximately 75˚C max, and tapping the bearing in or out. Caution: Do not heat the case with a torch. This will warp the case.  Using a press and a bearing drive, install the new bearing until it stops at the bottom of its housing. Ball and Needle Bearing Wear Caution: Do not remove the bearings for inspection. Removal may damage them.  Check the ball bearings.  Since the ball bearings are made to extremely close tolerances, the wear must be judged by feel rather than measurement. Clean each bearing in a high-flash point solvent, dry it (do not spin the bearing while it is dry), and oil it with engine oil.  Spin the bearing by hand to check its condition.  If the bearing is noisy, does not spin smoothly, or has any rough sports, replace it.  Check the needle bearings.  The rollers in a needle bearing normally wear very little, and wear is difficult to measure. Instead of measuring, inspect the bearing for abrasion, colour change, or other damage.  If there is any doubt as to the condition of a needle bearing, replace it.  Oil Seal Inspection  Inspect the oil seals.  Replace it if the lips are misshapen, discoloured (indicating that the rubber has deteriorated), hardened or otherwise damaged.

Fit the rear wheel (see Rear Wheel Installation).

Wheel Inspection  Place the jack under the frame so that the front or rear wheel is off the ground.  Spin the wheel lightly, and check for roughness or binding.  If roughness or binding is found, replace the hub bearings.  Visually inspect the front and rear axles for damage.  If the axle is damaged or bent, replace it. Spoke Inspection  Check that all spokes are tightened evenly.  If spoke tightness is uneven or loose, torque the spoke nipples evenly.  Spokes should be tighten until; when struck with a tuning fork they emit a clean note, minimum torque setting is only the lower limit. Torque minimum: Spoke Nipples: 1.5Nm 

Check the rim runout.

Warning: If any spoke breaks, it should be replaced immediately. A missing spoke places an additional load on the other spokes, which will eventually cause other spokes to break. Rim Inspection  Place the jack under the frame so that the front wheel or rear wheel is off the ground.  Inspect the rim for small cracks, dents, bending, or warping.  If there is any damage to the rim, it must be replaced.  Set a dial gauge against the side of the rim, and rotate the rim to measure the axial runout [A]. The difference between the highest and lowest dial readings is the amount of runout.  Set a dial gauge against the outer circumference of the rim, and rotate, the highest and lowest dial reading is the amount of runout. 188

 

If rim runout exceeds the service limit, check the wheel bearings first. Replace them if they are damaged. If the problem is not due to the bearings, correct the rim warp (runout). A certain amount of rim warp can be corrected by recentering the rim on spoked wheels. Loosen some spokes and tighten others within the standard torque to change the position of different parts of the rim. If the rim is badly bent, however, it must be replaced. Rim runout (with tire installed) Standard: Axial 0.5mm Service Limit: Axial 2mm

Radial: 0.8mm Radial: 2mm

Axle Inspection  Place the axle in V blocks that are 100mm [A] apart, and set a dial gauge on the axle at a point halfway between the blocks.  Turn the axle to measure the runout. The difference between the highest and lowest dial readings is the amount of runout.  If runout exceeds the service limit, replace the axle. Axle Runout/100mm Standard: 0.1mm or less Service Limit: 0.2mm Wheel Balance Note: To improve stability and decrease vibration at high speed, the front and rear wheels must be kept balanced. 

Check and balance the wheels when required, or when a tire is replaced with a new one.

Balance Inspection  Remove the wheel (see this chapter).  Support the wheel so that it can be spun freely.  Spin the wheel lightly, and mark [A] the wheel at the top when the wheel stops.  Repeat this procedure several times. If the wheel stops of its own accord in various positions, it is well balanced.  If the wheel always stops in one position, adjust the wheel balance. Balance Adjustment 189

If the wheel always stops in one position, provisionally attach a balance weight [A] on the rim at the marking. Rotate the wheel ¼ turn [B], and see whether or not the wheel stops in this position. If it does, the correct balance weight is being used. Attach a balance weight [A] loosely to the wheel rim. If the wheel rotates and the weight goes up, replace the weight with the next heavier size. If the wheel rotates and the weight goes down replace the weight with the nest lighter size. Repeat these steps until the wheel remains at rest after being rotated ¼ turn. Rotate the wheel another ¼ turn and then another 1/5 turn to see if the wheel is correctly balanced. Repeat the entire procedure as many times as necessary to achieve correct wheel balance. Permanently install the balance weight. Firmly press the balance weight on when finished. Balance weights:

5g

10g

20g

30g

Note: Balance weights are available from Norton Dealers in 5, 10, 20, 30 gram sizes. An imbalance of less than 5 grams will not usually affect running stability. Do not use four or more balance weight (more than 90 gram). If the wheel requires an excess balance weight, remove and disassemble the wheel to find the cause. Tyre Air Pressure Inspection/Adjustment  Using a tyre pressure gauge, measure the tyre pressure when the tyres are cold.  Adjust the tyre air pressure according to the following specifications, if necessary. Air Pressure (when cold) Front: 2.34bar (34psi) Rear: 2.62bar (38psi) Tyre Inspection Note: As the tyre tread wears down, the tyre becomes more susceptible to puncture and failure. An accepted estimate is that 90% of all tyre failures occur during the last 10% of tread life (90% worn). So it is false economy and unsafe to use the tyres until they are bald.  Remove any imbedded stones or other foreign particles from the tread.  Visually inspect the tyre for cracks and cuts, replacing the tyre in the case of bad damage. Swelling or high spots indicate internal damage, requiring tyre replacement.  Measure the tread depth at the centre of the tread with a depth gauge [A].  Take measurement at several places as the tyre may wear unevenly.  If any measurement is less than the service limit, replace the tyre. 190

Tread Depth Front: Standard: Service Limit: Rear: Standard: Service Limit:

3.5mm 2mm (legal Limit UK 1mm) 5mm 2mm (Legal Limit UK 1mm)

Note: To ensure safe handling and stability, use only the recommended standard tyres for replacement, inflated to the standard pressure. 

Check and balance the wheel when a tyre is replaced with a new one. Standard tyre Front: Make: Type: Size: Rear Make: Type: Size:

Dunlop Sportsmax Qualifier 120/70 X 17 Dunlop Sportsmax Qualifier 180/55 X 17

Tyre Removal Caution: Do not lay the wheel on the ground with the disc facing down. This can damage or warp the disc. Place blocks under the wheel so that the disc does not touch the ground.  

  

Remove the wheel from the motorcycle (see this chapter). To maintain wheel balance, mark the valve stem position on the tire with chalk so that the tire can be reinstalled in the same position. Take out the valve core to let the air out. When handling the rim, be careful not to damage the rim flanges. Lubricate the tyre beads and rim flanges on both sides with a soap and water solution or rubber lubricant. This helps the tyre beads slip off the rim flanges.

Caution: Never lubricate with mineral oil (engine oil) or gasoline because they will cause deterioration.  

Break the beads away from both sides of the rim with a bead breaker. Protect the rim with rim protectors , pry the tyre off.

191

Tyre Installation  Check the tyre rotation mark on the front and rear tyre and install it on the rim accordingly. Note: the direction of the tire rotation is shown by an arrow on the tire sidewall. 



Position the tire on the rim so that the valve is at the tire balance mark (the chalk mark made during removal or the yellow paint mark on a new tire). Check and adjust the air pressure after installing.

Hub Bearings (Wheel Bearings) Bearing Removal  Remove the wheel, take out the following:  Collar(s)  Coupling (rear hub)  Grease Seals  Circlip  Take the bearings out of the hub, using bearing remover. Caution: Do not lay the wheel on the ground with the disc facing down. This can damage or warp the disc. Place blocks under the wheel so that the disc does not touch the ground. Bearing Installation  Before Installing the wheel bearings, blow any dirt or foreign particles out of the hub with compressed air to prevent contamination of the bearings.  Replace the bearings with new ones.  Press in the bearings until they bottom out. Note: Install the Bearing so that the marked side or sealed side faces out. 

Install: o New Circlip o Collar o Right Bearing o Left Bearing

  

Replace the grease seals with new ones. Apply high temperature grease to the grease seal lips. Press in the grease seal so that the seal surface is flush with the end of the hole. 192

Bearing Inspection  Since the hub bearings are made to extremely close tolerances, the clearance cannot normally be measured. Caution: Do not remove any bearings for inspection. If any bearings are removed, they will need to be replaced with new ones.   

Turn each bearing in the hub back and forth [A] while checking for play, roughness, or binding. If bearing play, roughness, or binding is found, replace the bearing. Examine the bearing seal [B] for damage or leakage. If the seal is damaged or is leaking, replace the bearing.

Chain slack Inspection  Set the motorcycle up on its side stand.  Check to see that the notches [A] on the chain adjusters [B] on both sides are in the same relative position.  If they are not, adjust the chain slack and align them. Warning: Misalignment of the wheel will result in abnormal wear and may result in an unsafe riding condition. Note: Clean the chain if it is dirty, and lubricate it if it appears dry.   

Check the chain slack. Turn the rear wheel to find the position where the chain is tightest. Measure the spacer (chain slack) [A] between the chain and the step of the chain slipper as shown. Chain Slack Standard: Too Tight: Too Loose:



35 ~ 40 mm Less than 35 mm More than 45 mm

If the chain slack exceeds the standard, adjust it.

Chain Slack Adjustment  Loosen the axle nut [A].  Turn the chain adjusters [B] evenly until the drive chain has the specified amount of slack.  Check to see that the notches [C] on both sides are in the same relative position.

A

B

Warning: Misalignment of the rear wheel will result in abnormal wear and may result in an unsafe riding condition. 

Tighten the rear axle nut. Torque – Rear Axle Nut: 110Nm 197

Returning call Warning: If the axle nut is not securely tightened, an unsafe riding condition may result.  

Turn the wheel, measure the chain slack again at the tightest position, and readjust if necessary. Check the rear brake effectiveness.

Warning: Do not attempt to ride the motorcycle until a full brake pedal is obtained by pumping the brake pedal until the pads are against the disc. The brake will not function on the first application of the pedal if this is not done. Chain Wear Inspection  Rotate the rear wheel to inspect the drive chain for damage rollers, and loose pins and links.  If there is any irregularity, replace the drive chain.  Lubricate the drive chain if it appears dry (see this chapter).  Stretch the chain taut by hanging a (10kg) weight [A] on the chain.  Measure the length of 20 links [B] on the straight part [C] of the chain from the pin centre of the 1st pin to the pin centre of the 21st pin. Since the chain may wear unevenly, take measurements at several places.  If any measurements exceed the service limit, replace the chain. Also, replace the front and rear sprockets when the drive chain is replaced. Chain 20-Link Length Standard: 317.5 ~ 318.2 mm Service Limit: 323 mm Warning: If the drive chain wear exceeds the service limit, replace the chain or an unsafe riding condition may result. A chain that breaks or jumps off the sprocket could snag on the engine sprocket or lock the rear wheel, severally damaging the motorcycle and causing it to go out of control. Standard chain Make: REGINA Type: REGINA 525 (137ZRP) Z-RING Link: 106 links Chain Lubrication  If the chain is especially dirty, it should be washed in diesel oil or kerosene, and afterward soaked in heavy oil. Shake the chain while it is in the oil so that oil will penetrate to the inside of each roller. 198



An effective, good quality lubricant specially formulated for chains is best for regular chain lubrication.  If a special lubrication is not available, heavy oil such as SAE 90 is preferred to lighter oil because it will stay on the chain longer and provide better lubrication. Caution: The O-rings between the side plates seal in the lubricant between the pin and the bushing. To avoid damaging the O-rings and resultant loss of lubricant, observe the following rules. Use only kerosene or diesel oil for cleaning an O-ring drive chain. Any other cleaning solution such as gasoline or trichloroethylene will cause deterioration and swelling of the O-rings. Immediately blow the chain dry with compressed air after cleaning. Complete cleaning and drying the chain within 10 minutes. 



Apply the oil to the sides of the rollers so that the oil will penetrate to the rollers and bushings. Apply oil to the Orings so that the O-rings will be coated with oil. Wipe off any excess oil. Oil Applied Areas [A]

O-ring [B]

Brake Fluid Warning: When working with the disc brakes, observe the precautions listed below.   

  



 

Never reuse old brake fluid. Do not use fluid from a container that has been left unsealed or that has been open for a long time. Do not mix two types and brands of fluid for use in the brakes. This lowers the brake fluid boiling point and could A cause the brake to be ineffective. It may also cause the rubber brake parts to deteriorate. Don`t leave the reservoir cap [A] off for any length of time to avoid moisture contamination of the fluid. Don`t change the fluid in the rain or when a strong wind is blowing. Except for the disc pads and disc, use only disc brake fluid, isopropyl alcohol, or ethyl alcohol for cleaning brake parts. Do not use any other fluid for cleaning these parts. Gasoline, engine oil, or any other petroleum distillate will cause deterioration of the rubber parts. Oil spilled on any part will be difficult to wash off completely and will eventually deteriorate the rubber used in the disc brake. When handling the disc pads or discs, be careful that no disc brake fluid or any oil gets on them. Clean off any fluid or oil that inadvertently gets on the pads or discs with a high-flash point solvent. Do not use one which will leave an oily residue. Replace the pads with new ones if they cannot be cleaned satisfactorily. Brake fluid quickly ruins painted surfaces; any spilled fluid should be completely washed away immediately. If any brake line fittings or the bleed valve is opened at any time, the AIR MUST BE BLED FROM THE BRAKE.

Brake Fluid Recommendation Note: Recommended fluids are given in the table below. If none of the recommended fluids are available, use extra heavy-duty brake fluid only from a container marked D.O.T. 3 OR 4.

NOTE: Brake fluid of D.O.T. 4 is installed in the brake system when shipped. Brake Fluid: Grade Brand Specification

D.O.T. 4 / D.O.T. 3 Fuchs Silkolene FMVSS 116 D.O.T. 4, D.O.T. 3, ISO 4925 AND SAE J 1703, (or above)

216

Brake Fluid Level Inspection In accordance with the Periodic Maintenance Chart, inspect the brake fluid level in the front and rear brake fluid reservoir  

Check the front and rear brake fluid reservoir level is above the lower line [A] and below the upper line [B]. Hole the reservoir when checking brake fluid level.

B A

Warning: Change the fluid in the brake line completely if the fluid must be refilled but the type and brand of the fluid that already is in the reservoir are unidentified. 

If the fluid level is lower than the lower level line, fill the reservoir to the upper level line [A] in the reservoir with the same type and brand of the fluid that already is in the reservoir.

Brake fluid changing Note: The procedure to change the front brake fluid is as follows. Changing the rear brake fluid is the same as for the front brake.         

Remove the reservoir cap. Attach a clear plastic hose to the bleed valve on the caliper, and run the other end of the hose into a container. Fill the reservoir with new brake fluid. Change the brake fluid as follows: Open the bleed valve [A]. Apply the brake lever and hold it [B]. A Close the bleed valve [A]. Release the brake lever [B]. Check the fluid level in the reservoir often, replenishing it as necessary.

Note: If the fluid in the reservoir runs completely out any time during fluid changing, air will enter the line, and the system must be bled. 

Repeat this operation until fresh fluid comes out into the plastic hose or the colour of the fluid changes. Warning: Do not mix two brands of fluid. Change the brake fluid in the brake line completely if the brake fluid must be refilled but the type and brand of the brake fluid that is already in the reservoir are unidentified.

A

217

Torque – Bleed Valves: 7.8Nm 

Apply the brake lever forcefully for a few seconds, and check for fluid leakage around the fittings.

Warning: If the brake lever or pedal has a soft or “spongy feeling” when it is applied, there might be air in the brake line or the brake may be defective. Since it is dangerous to operate the motorcycle under such conditions, bleed the air from the brake line immediately. Brake Line Air Bleeding Note: The procedure to bleed the front brake line is as follows. Bleeding the rear brake line is the same as for the front brake.   

Bleed the air whenever brake parts are replaced or reassembled. Remove the reservoir cap and fill the reservoir with new brake fluid. Slowly pump the brake lever several times until no air bubbles can be seen rising up through the fluid from the hose at the bottom of the reservoir. This bleeds the air A from the mast cylinder and the brakes line.

Note: Tap the brake hose lightly going from the caliper to the reservoir side and bleed the air off at the reservoir.      

Attach a clear plastic hose to the bleed valve on the caliper, and run the other end of the hose into a container. Bleed the brake line and caliper as follows: Hold the brake lever applied [A]. Quickly open and close the valve [B]. Release the Brake Level [A]. B The fluid lever must be checked several times during bleeding operation and replenished as necessary.

Note: If the fluid in the reservoir runs completely out any time during bleeding, the bleeding operation must be done over again from the beginning since air will have entered the line. If the brake lever or pedal action still feels soft or “spongy”, tap the brake hose from bottom to top and air will rise up to the top part of the hose. Slowly pump the brake lever or pedal in the same manner as above. Torque – Bleed Valves: 8 Nm 

Apply the brake lever forcefully for a few seconds, and check for fluid leakage around the fittings. 218

Front Caliper Removal  Drain the front brake fluid (see Brake Fluid Change).  Remove banjo bolt [A].  Remove caliper bolts [B] and take off the caliper [C].  If the caliper is to be disassembled after removal and if compressed air is not available, remove the pistons using the following steps before disconnecting the brake hose from the caliper.  Remove the pads (see Brake Pad Removal).  Insert a wooden board 5mm thick inside the caliper opening (see this chapter).  Pump the brake lever until the pistons push the wooden board.  Remove the caliper.  Remove the board and pull out the pistons by hand.

Remove the dust seal and fluid seal.

Caliper Assembly  It is recommended that the fluid seal, which is removed, be replaced with a new one. 220

    

Replace the dust seals if they are damaged. Install the fluid seal. Either side of the seal may face outboard. Apply brake fluid to the cylinders, pistons, and fluid seals (piston seals), and push the pistons into the cylinders by hand. Take care that neither the cylinder nor the piston skirt gets scratched. Install the anti rattle spring in the caliper. Install the pads (see Brake Pad Installation).

Caliper Fluid Seal Damage Note: The fluid seals around the piston maintain the proper pad/disc clearance. If the seals are not satisfactory, pad wear will increase, and constant pad drag on the disc will raise brake and brake fluid temperature. 



Replace the fluid seals under any of the following conditions: (a) fluid leakage around the pads; (b) Brakes overheat (c) there is a large difference in inner and outer pad wear; (d) the seal is stuck to the piston. If the fluid seal is replaced, replace the dust seal as well. Also, replace all seals every other time the pads are changed.

Service Limit 3.3mm 225

Rear - 5mm ± 0.15 Runout: 0.2 mm or less

4.3mm 0.3mm

Disc Cleaning Note: Poor braking can be caused by oil on a disc. Oil on a disc must be cleaned off with an oilless cleaning fluid such as trichloroethylene or acetone. Warning: These cleaning fluids are usually highly flammable and harmful if breathed for prolonged periods. Be sure to heed the fluid manufacture’s warning.

Disc Warp Inspection  Using the jack, raise the front or the rear wheel off the ground (see Wheels/Tire chapter).  Set the dial gauge [A] against the disc.  For the front disc, turn the handlebar fully to one side.  Rotate the wheel [C] to measure disc runout. The difference between the highest and lowest dial reading is the amount of runout.  If disc runout exceeds the service limit, replace the disc. Disc Runout Standard: 0.2 mm or less Service Limit: 0.3 mm Brake Hose Removal  Drain the brake fluid (see Brake Fluid Change).  Remove the banjo bolts [A] at both ends of the brake hose [B] and pull the hose off the motorcycle. There is a copper washer on each side of the hose fitting.  When removing the brake hose, temporarily secure the end of the brake hose to some high place to keep fluid loss to a minimum.  Immediately wash away any brake fluid that spills. Caution: Brake fluid quickly ruins painted surfaces; any spilled fluid should be completely washed away immediately. Brake Hose Installation  Using a new copper washer for each side of the hose fitting, tighten the banjo bolt. Torque – Banjo Bolts: 25Nm   

When installing the hoses, avoid shaft bending, kinking, flattening or twisting. Run the brake hose according to the Cable, Wire and Hose Routing section in the General Information chapter. Fill the brake line with the brake fluid (see Brake Fluid Changing). 226

Rear Suspension Warning: Ensure that the basic factory settings are intact before riding the motorcycle. If making adjustments, only adjust one aspect at a time in small increments. Spring Preload – Static Sag – Rider - Sag Note: Spring preload affects the ride height of the motorcycle and the fork angle. The Following should be performed on a flat surface.  Lift the motorcycle off the ground using a work stand so that the front and rear wheels are off the ground and unloaded.  Measure the distance from the centre of the rear wheel axle to the centre of the top rear suspension mount [R1].  Measure the distance from the bottom of the lower yoke (lowest point) to the centre of the front wheel axle [F1].  With the motorcycle on the ground so the motorcycle is under its own weight, repeat the measuring procedure above for [R2] and [F2].  Sit on the motorcycle in full riding gear in a normal riding position; repeat the measuring procedure for [R3] and [F3]. Note: The following set up is based on a single rider in full gear to a mass of 90Kg. Static Sag Conventional forks – [R1-R2] [474-463] Rear: 11 mm ± 3mm [F1-F2] [522-477] Front: 45 mm ± 3mm Static Sag USD Forks [R1-R2] [474-463] Rear: 11 mm ± 3mm [F1-F2] [510-475] Front: 35 mm ± 3mm Rider Sag Conventional [R1-R3] [474-440] Rear: 34 mm ± 3mm [F1-F3] [522-467] Front: 55 mm ± 3mm Rider Sag USD Forks [R1-R3] [474-440] Rear: 34 mm ± 3mm [F1-F3] [510-465] Front: 45 mm ± 3mm  

If the measurements differ significantly from the table above, adjust the spring preload (see Spring Preload Adjustment). If the Rider Sag still differs significantly you may need to replace the spring. 240

Warning: Incorrect spring rate may result is poor handling characteristics. Preload Adjustment  Turn the screw [A] on the hydraulic adjuster to set the A spring preload.  Turn clockwise to increase preload, turn anti clockwise to decrease.  To set the rider sag adjustment (see this chapter) turn the preload adjuster anti clockwise until it stops, and then turn clock wise to the first audible click. From this click turn the preload adjuster clockwise to the recommended position. Note: One full turn of the preload adjuster equates to 2/3mm (0.66 mm) of spring preload. Preload – 7 full turns from fully out (two rings on the adjust should be visible [A])

A

Note: Increasing the amount of preload on the rear shock will reduce the amount of both static and rider sag. Reducing the preload will increase the sag values.   

Adjust both the left and right hand rear suspension springs in sequence to the same position. Changing the spring preload will change the ride height and affect the handling. It is critical that the spring preload is correctly set; if the spring preload is not correctly set all other suspension adjustments may not give desired handling characteristics.

Compression Damping Adjustment Note: Compression damping controls the energy absorbed when the rear wheel is being loaded or hits a bump. Standard settings are based on a 90 kg rider (this includes riding gear). 



A

To adjust the compression damping turn the adjuster [A] clockwise to increase damping, and anti clockwise to decrease damping. To reset the adjuster turn the adjuster clockwise to fully closed position (zero (0) position), then turn anti clockwise to open.

Rear Compression Damping – 3 clicks out from fully closed Caution: Do not force the damping adjuster, delicate sealing surfaces could be damaged. 241

Rebound Damping Adjustment. Note: Rebound damping controls the energy absorption when the shock absorber is being extended and controls how fast the shock absorber returns to its normal position after being compressed.  

To adjust the damping, turn the adjuster [A] on the piston shaft clockwise to increase damping, anti clockwise to decrease it. To reset the damping, turn the adjuster clockwise (right) to fully closed position, and then anti clockwise (left) to the specified range. Rear Rebound Damping – 18 Clicks out from fully closed

Warning: If both suspension units are not adjusted equally, handling may be impaired and a hazardous condition may result. Ride Height Adjustment Note: Adjusting the length of the rear suspension will directly affect the steering geometry and handling of the motorcycle

B

Caution: Make very small adjustments at a time as they can make a significant difference.    

Remove the shock absorbers from the motorcycle (see this chapter). Slacken off the lock nut [A]. Turn the adjuster nut [B] to the desired length. One turn of the spring retainer results in 1mm of shock absorber length. Rear Shock Absorber Length: 380 mm +8/-2mm

If the bike is nervous / moving a lot or has a high feeling entering corners. Close the rebound adjuster two clicks. Fine tune by one click at a time

Caution: Always start from original factory settings and test run after making changes. Compression Damping Recommended Adjustment Range Compression Damping Range: ± 2 clicks from original settings    

If the motorcycle feels soft / unstable or is using too much wheel travel and the spring rate is correct. Close the compression adjuster by one click. This will controle reduce the motorcycle from falling throught the stroke too quickly. If the motorcycle feels high / has poor grip when opening the throttle or does not feel smooth over small bumps during acceleration. Open the Compression Adjuster by one click.

Caution: Always start from original factory settings and test run after making changes, if improvements have been made, repeate the procedure from the start again to check. Always check tire pressures before making suspension adjustements and take note of the conditions such as air temperature. Caution: Preventive maintenance and regular inspection reduces the risk of function disturbance. Rear Suspension Cleaning  Clean the rear suspension unit externaly with a soft detergent. Using compressed air ensure all dirt is removed, lift the bump rubber and clean the area below. Keep the shock absorber clean and spray with a water displacing spray which will not deteriate the rubber, after cleaning, wash off excessive oil with a cloth. Caution: Never spray water directly into the adjuster units or ball joints. 243

Rear Suspension Inspection  Check the ball joint for excessive play or stiction.  Check the piston shaft for leakage and damage.  Check the shock absorber body for external damage.  Check the reservoir for external damage that can restrict the floating piston from moving freely.  Check for excessive wear of rubber components.  Check the attachment points between frame, swingarm, and shock. Warning: Do not change the gas pressure this required specialist high pressure nitrogen equipment.

Swingarm Pivot Check    

Check the pivot of the Swingarm and suspension mounting points. Raise the rear wheel off the ground (see Wheels/Tires chapter). A Move the Swingarm [A] up and down to check for abnormal friction, and push and pull it to check for bearing play. A small amount of play on the pivot is normal and no corrective action is needed. However, if excessive play is felt, check the Swingarm and suspension link bearings for wear and replace them if necessary.

Warning: Installation of new bearings in the Swingarm may cause too stiff rear suspension. Test ride the motorcycle slowly and prudently until the suspension becomes normal. Swingarm Bearing, Sleeve Inspection 

The rollers in a needle bearing normally wear very little, and wear is difficult to measure. Instead of measuring, inspect the bearing in the Swingarm for abrasion, colour change, or other damage.

If there is any doubt as to the condition of any of the needle bearings or sleeves, replace all the sleeves, and needle bearings as a set.

Precautions Note: There are a number of important precautions that are musts when servicing electrical systems. Lean and observe all the rules below.        

 

Do not reverse the battery lead connections. This will burn out the diodes in the electrical parts. Always check battery condition before condemning other parts of an electrical system. A fully charged battery is a must for conducting accurate electrical system tests. The electrical system should never be struck sharply, as with a hammer, or allowed to fall on a hard surface. Such a shock to the parts can damage them. To prevent damage to electrical parts, do not disconnect the battery leads or any other electrical connections when the ignition switch is on, or the engine is running. Because of the large amount of current, never keep the starter switch pushed when the starter motor will not turn over, or the current may burn out the starter motor windings. Do not use a meter illumination bulb for other than the voltage or wattage specified in the wiring diagram, as the meter panel could be warped by excessive heat radiated from the bulb. Take care not to short the leads that are directly connected to the battery positive (+) terminal to the chassis ground. Troubles may involve one or in some cases all items. Never replace a defective part without determining what CAUSED the failure. If the failure was caused by some other item or items, they too must be repaired or replaced, or the new replacement will soon fail again. Make sure all connections in the circuit are clean and tight, and examine wires for signs of burning, fraying, etc. Poor wires and bad connections will affect electrical systems operation. Measure coil and winding resistance when the part is cold (at room temperature).

Electrical Wiring Wiring Inspection  Visually inspect the wiring for signs of burning, fraying, etc.  If any wiring is poor, replace the damaged wiring.  Pull each connector apart and inspect it for corrosion, dirt, and damage.  If the connector is corroded or dirty, clean it carefully. If it is damaged, replace it.  Check the wiring for continuity.  Use the wiring diagram to find the ends of the lead which is suspected of being a problem.  Connect the hand tester between the ends of the leads.  Set the tester to 1 Ω range, and read the tester.  If the tester does not read 0 Ω, the lead is defective. Replace the lead or the wiring harness if necessary.

314

Battery Battery Removal  Remove:  Seat (see Frame chapter).  Fuel Tank (see Fuel System chapter)  Remove the battery strap.  Disconnect the battery negative ( - ) cable first, and then the positive ( + ) cable.  Take out the battery. Battery Installation  Connect the battery positive ( + ) cable first, and then the negative ( - ) cable.  Run the battery cables according to the Cable, Wire, and Hose Routing section of the General Information chapter.  Install:  Battery Strap  Fuel Tank (See Fuel System chapter)  Seat (see Frame chapter) Electrolyte Filling Note: Only use a maintenance free battery and follow manufactures instructions to fill if required. Initial Charge  Change at 0.9 A for 2~3 hours Precautions  Battery does not need topping up. Warning: Do not top up as sealed battery type only.  



Refreshing charge: If an engine will not start, a horn sounds weak, or lights are dim, it indicates the battery has been discharged. Give refresh change for 5 to 10 hours with charge current shown in specification (see Refreshing Charge). When a fast charge is inevitably required, do it following precisely the maximum charge current and time conditions indicated on the battery.

Caution: This battery is designed to sustain no unusual deterioration if refresh-charged according to the method specified above. However, the battery performance may be reduced noticeably if charged under conditions other than given above. Never remove the sealing plug during refresh charge. 315





When you do not use the motorcycle for months, give a refresh charge before you store the motorcycle and store it with the negative lead removed. Give a refresh change every six months during storage. Battery life: o If the battery will not start the engine even after several refresh charges, the battery has exceeded its useful life. Replace it. (Provided, however, the vehicle`s starting system has no problem.)

Warning: Keep the battery away from sparks and open flames during charging, since the battery gives off an explosive gas mixture. When using a battery charger, connect the battery to the charger before turning on the charger. This procedure prevents sparks at the battery terminals which could ignite any battery gasses. No fire should be drawn near the battery, or no terminals should have the tightening loosened. The battery contains acid. Be careful not to have it touch your skin or eyes. If it touches, wash it off with liberal amount of water. Get medical attention if severe. Charging Condition Inspection Note: Battery charging condition can be checked by measuring battery terminal voltage.    

Remove: Seat (see Frame chapter) Fuel Tank (see Fuel system chapter) Disconnect the battery terminal leads.

Caution: Be sure to disconnect the negative terminal first. 

Measure the battery voltage Battery Terminal Voltage: Standard: 12.6 V more

Refreshing Charge  Remove the battery (see Battery Removal).  Refresh-charge by following method according to the battery terminal voltage Caution: This battery is a sealed type. Never remove the seal cap even at charging. Never add water. Charge with current and time as stated below. 

Terminal Voltage: 11.5 ~ 12.6 V Standard Change: Quick Charge:

0.9 A x 5 ~ 10 h 4.0 A x 1 hour

316

Caution: If Possible do not quick charge. If the quick charge is done due to unavoidable circumstances, do standard change later on. 

Terminal Voltage: less than 11.5 V Charging Method: 0.9 A x 20 Hours

Note: Raise the voltage (25 V maximum), and charge for about 5 minutes. If ammeter shows no change in current after 5 minutes, a new battery is required. The current, if it can flow into the battery, tends to become excessive. Adjust the voltage as often as possible to keep the current at standard (0.9 A).  

Determine battery condition after refreshing charge. Determine the battery condition 30 minutes after completion of the charge by measuring the terminal voltage according to the table below. 12.6 V or higher: 12.0 ~ 12.6 V or lower: 12.0 V or lower:

Good > No action required Charge insufficient > Recharge Unserviceable > Replace

Alternator Alternator/Clutch Cover Removal  Alternator cover removal (see Clutch chapter) Alternator/Clutch Cover Installation  Alternator cover Installation (see Clutch chapter)  Fill the gearbox with oil (see Engine Lubrication System chapter).  Route the alternator leads in accordance with the Cable, Wire, and Hose Routing section in the General Information chapter.

Charging System Regulator / Rectifier Removal  Pull off the regulator/rectifier rubber boot [A] and connector [B].  Remove the regulator/rectifier bolts [C].  Remove the regulator/rectifier [D].

Regulator/Rectifier Output Voltage Inspection  Check the battery condition (see battery section).  Warm up the engine to obtain actual alternator operating conditions.  Check that the ignition switch is turned off and connect the hand tester to the battery terminals.  Start the engine, and note the voltage readings at various engine speeds with the headlight turned on and off. The readings should show nearly battery voltage when the engine speed is low, and, as the engine speed rises, the readings should also rise. But they must be kept under the specified voltage. Regulator Voltage - @ Meter Range 25 V: 14 ~ 15V    

Turn off the ignition switch to stop the engine and disconnect the hand tester. If the regulator/rectifier output voltage is kept between the vales given above, the charging system is considered to be working normally. If the output voltage is much higher than the values specified in the table, the regulator/rectifier is defective or the regulator/rectifier leads are loose or open. If the battery voltage does not rise as the engine speed increases, then the regulator/rectifier is defective or the alternator output is insulated for the loads. Check the alternator and regulator/rectifier to determine which part is defective.

Alternator Inspection 319

Note: There are three types of alternator failures: short, open (wire burned out), or less in rotor, or rotor magnetism. A short or open in one of the coil wires will result in either a low output, or no output at all. A loss in rotor magnetism, which may be caused by dropping or hitting the alternator by leaving it near an electromagnetic field, or just by aging, will result in a low output.  To check the alternator output voltage, do the following procedures.  Disconnect the alternator Connector [A].  Connect the hand tester to any two out of the three output pins coming from the alternator.  Start the engine  Run it at three different rev ranges  Set the meter to 250 V range Voltage – Alternator: more than 34 V 

    

If the output voltage shows the value above, the alternator operates properly and the regulator/rectifier is damaged. A much lower reading than given in the table indicates that the alternator is defective. Check the stator coil resistance as follows: Stop the engine. Disconnect the alternator connector. Connect the hand tester to two of the three output wires. Note the readings (total 3 measurements). Resistance – Stator: 0.3 – 1.0 Ω



  

If there is more resistance than shown above, or no hand tester reading (infinity) for any of the two leads, the stator has an open lead and must be replaced. Much less than this resistance means the stator is shorted, and must be replaced. Using the highest resistance range of the hand tester measure the resistance between each of the alternator leads and chassis ground. Any hand tester readings less than infinity indicates a short, necessitating stator replacement. If the stator coils have normal resistance, but the voltage check showed the alternator to be defective, then the rotor magnetism has probably weakened, and the rotor must be replaced.

Regulator/Rectifier Inspection  Turn off the ignition switch.  Disconnect the regulator/rectifier connector.  Set the hand tester to the 1 kΩ range and make the measurements shown below.  If tester readings are not as specified, replace the regulator/rectifier. Range x 1 k Ω

Ignition System

Warning: The ignition system produces extremely high voltage. Do not touch the spark plug, ignition coil, or spark plug lead while the engine is running, or you could receive a severe electrical shock. Caution: Do not disconnect the ECU connectors while the engine is running. This is to prevent ECU damage. Spark Plug Removal/Installation  Remove the HT leads from spark plug cap  Remove or install the spark plug using the spark plug wrench Torque – Spark Plug: 12 Nm Spark Plug Cleaning/Inspection  Clean the spark plug, preferably in a sandblasting device and then clean off any abrasive particles. The plug may also be cleaned using a high flash point solvent and a copper wired brush or other suitable tools. If the center electrode or side electrode are corroded or damaged, or if the insulator is cracked, replace the plug. Use the standard spark plug or its equivalent. Spark Plug Gap  Measure the gap with a wire-type thickness gauge.  If the gap is outside the service limit replace the spark plug. Spark plug Gap – Standard: 0.8 mm Service Limit: 1.0 mm Ignition Coil Removal  Remove the fuel tank (see Fuel System chapter).  Pull the spark plug lead off the spark plug.  Disconnect the coil lead [A]  Remove coil bolt [B]  Remove coil [C] Ignition Coil Installation  Install ignition coil [A] as shown  Install ignition coil bolt [B] 321

Ignition Coil Inspection  Remove the ignition coil (see this chapter).  Measure the arcing distance with a suitable commercially available coil tester to check the condition of the ignition coil.  Connect the ignition coil with the spark plugs left attached to the end of the spark plug leads to the tester in the manner prescribed by the manufacture and measure the arcing distance. Ignition Coil Arcing Distance: 7 mm or more Warning: To avoid extremely high voltage shocks, do not touch the ignition coil body or leads.               

If the distance reading is less than the specified value, the ignition coil or spark plug cap is defective. To determine which part is defective, measure the arcing distance again with the spark plug cap removed from the ignition coil. Remove the cap by turning it counter clockwise. If the arcing distance is subnormal as before, the trouble is with the ignition coil itself. If the arcing distance is now normal, the trouble is with the spark plug cap. If the coil tester is not available, the coil can be checked for a broken or badly shorted winding with a hand tester. Note: The hand tester cannot detect layer shorts and shorts resulting from insulation brake down under high voltage. Measure the primary winding resistance as follows. Connect the tester between the coil terminals. Set the tester between the coil terminals. Measure the secondary winding resistance as follows. Remove the plug cap by turning it counter clockwise. Connect the tester between the spark plug lead and terminal. Set the tester to the 1 k Ω range and read the tester. Measure primary winding resistance [A]. Measure secondary winding resistance [B].

Pickup Coil Resistance 100 ~200 Ω (x 10 Ω)   

If there is more resistance than the specified value, the coil has an open lead and must be replaced. Much less than this resistance means the coil is shorted, and must be replaced. Using the highest resistance range of the hand tester, measure the resistance between the pickup coil lead terminals and chassis ground. Any Hand tester reading less than infinity indicates a short, necessitating replacement of the pickup coil assembly.

Turn Signal Flasher Unit Inspection 328

Note: Since the turn signal relay is designed to operate correctly only when two turn signals (one front and one rear) and the turn signal indicator light are properly connected in the circuit, trouble may result from a burned out bulb, a bulb of incorrect wattage, loose wiring, as well as from a defect in the relay itself. In general, if the trouble with the circuit is common to both right and left turn signals, it is probably caused by a defective turn signal flasher unit, although it may be due to a bad switch, wiring, or battery. If the trouble is with only one side - either right or left, then the flasher unit is not at fault since one is used for both sides.  

Remove the seat (see Frame chapter) Check the condition of the flasher unit [A] for the following problems:

  

Neither right or left turn signal comes on at all: Check the battery voltage is normal. Unplug the flasher unit leads and use the hand tester to check that there is continuity (close to zero ohms) between the relay terminals. If there is no tester reading (infinity) or if there are several ohms resistance, replace the flasher unit with a new one. Turn the tester to the 25 ~V DC range, connect the (+) tester lead to the one lead that was disconnected from the flasher unit, and connect (-) tester lead to the other lead. With the ignition switch on, first switch the turn signal switch to the R and then to the L position. The tester should register battery voltage at either position. If it does not, the fuse, ignition switch, or wiring is at fault. Both right or left turn signals come on and stay on or flash too slowly: Check that battery voltage is nominal. Check that all wiring connections are good. Check that the turn signal bulbs and indicator bulb are of the correct wattage. If all of the above check well, replace the flasher unit. A signal light on one side comes on: Either the light that does not come on is burned out or of the incorrect wattage, or the wiring is broken or improperly connected. Neither light on one side comes on. Unless both lights for that side are burned out, the trouble is with the turn signal switch. Flashing rate is too fast: If this occurs on both the right and left sides, check that the battery is not being overcharged. If the alternator and the battery voltage are normal, replace the turn signal flasher unit. If this occurs on only one side, one or both of the turn signal bulbs are too high wattage.

Connect point 5 briefly to the positive supply, the needle should move. If it does not shows anything then the unit is faulty and should be replaced.

Switches Switch Inspection  Using the hand tester, check to see that the switch connections as shown on the wiring schematic have continuity (about zero ohms) when closed.  If it does not as specified, check all connections, if the switch has an open or short repair it or replace with a new one. Fuses Main Fuses Removal  Remove the fuel Tank (see Fuel System chapter)  Remove the fuse [A] from housing [B].

Auxiliary Fuse removal  Remove the seat (see Frame chapter).  Remove fuse box cover [A].  Remove relevant fuses by pulling. 331

Fuse Installation  If a fuse fails during operation, inspect the electrical system to determine the cause, and then replace it with a new fuse of proper amperage. Fuse Inspection  Remove the fuse (see Fuse Removal).  Inspect the fuse element.  If it is blown out, replace the fuse. Before replacing a blown fuse, always check the amperage in the affected circuit. If the amperage is equal to or greater than the fuse rating, check the wiring and related components for a short circuit. Caution: When replacing a fuse, be sure the new fuse matches the specified fuse rating for that circuit. Installation of a fuse with a higher rating may cause damage to wiring and components.

Additional Considerations for Racing This motorcycle has been manufactured for use in a reasonable and prudent manner and as a vehicle only. However, some may wish to subject this motorcycle to abnormal operation, such as would be experienced under racing conditions. NORTON STRONGLY RECOMMENDS THAT ALL RIDERS RIDE SAFELY AND OBEY ALL LAWS AND REGULATIONS CONCERNING THEIR MOTORCYCLE AND ITS OPERATION. Racing should be done under supervised conditions, and recognized sanctioning bodies should be contacted for further details. For those who desire to participate in competitive racing or relate use, the following information may prove useful. However, please note the following important notes.  You are entirely responsible for the use of your motorcycle under abnormal conditions such as racing and Norton shall not be liable for damages which might arise from such use.  Norton’s Limited Motorcycle Warranty and Emissions Systems Warranty specifically exclude motorcycles which are used in competition or related uses. Please read the warranty carefully.  When the motorcycle is operated on public roads, it must be in its original state in order to ensure safety and compliance with applicable regulation. Spark Plug The spark plug ignites the fuel and air mixture in the combustion chamber. To do this effectively and at the proper time, the correct spark plug must be used, and the spark plug must be kept clean and the gap must be within the specified range. Tests have shown the plug listed in the “General Information” Carbon Fouling chapter to be the best plug for general use. Since spark plug requirements change with the ignition and fuel adjustments and with riding conditions, whether or not a spark plug of the correct heat range is used should be determined by removing and inspecting the plug. When a plug of the correct heat range is being used, the electrodes Oil Fouling will stay hot enough to keep all the carbon burned off, but cool enough to keep from damaging the engine and the plug itself. This temperature is about 400 ~ 800˚C and can be judged by noting the condition and colour of the ceramic insulator around the centre electrode. If the ceramic is clean and of a light brown colour, the plug is operating at the right temperature. A spark plug for higher operating temperatures is used for racing such a plug is designed for better cooling efficiency so that it will not overheat and thus is often called a “colder” plug. If a spark plug with too cool a heat range is used – that is, a “cold” plug that cools itself too well the plug will stay too cool to burn off the carbon, and the carbon will collect on the electrodes and the ceramic insulator. The carbon on the electrodes conducts electricity, and can short the centre electrode to ground by either coating the ceramic insulator or bridging across the gap. Such a short will prevent an effective spark. Carbon build-up on the plug can also cause other troubles. It can heat up red-hot and cause pre-ignition and knocking, which may eventually burn a hole in the top of the piston.

334

Spark Plug Inspection  

Remove the spark plug and inspect the ceramic insulator. Whether or not the right temperature plug is being used can be ascertained by noting the condition of the ceramic insulator around the electrode. A light brown colour indicated the correct plug is being used. If the ceramic is black, it indicates that the plug is firing at too low a temperature, so the next hotter type should be used instead. If the ceramic is white, the plug is operating at too high a temperature and it should be replaced with the next colder type.

Normal Operation

Normal Operation

Caution: If the spark plug is replaced with a type other than the standard plug, make certain the replacement plug has the same thread pitch and reach (length of threaded portion) and the same type electrode (regular type or projected type) as the standard plug. If the plug reach is too short, carbon will build up on the plug hole threads in the cylinder head, causing overheating and making it very difficult to insert the correct spark plug later. If the plug reach is too short, carbon will build up on the plug hole threads in the cylinder head, causing overheating and making it very difficult to insert Over Heating the correct spark plug later. If the reach is too long, carbon will build up on the exposed spark plug threads causing overheating, pre-ignition, and possibly burning a hole in the piston top. In addition, it may be impossible to remove the plug without damaging the cylinder head. Note: The heat range of the spark plug functions like a thermostat for the engine. Using the wrong type of spark plug can make the engine run too hot (resulting in engine damage) or too cold (with poor performance, misfiring, and stalling).

Check the tightness of the bolts and nuts listed here in accordance with the Periodic Maintenance Chart. Also, check to see that each cotter pin is in place and in good condition.

Note: For the engine fasteners, check the tightness of them when the engine is cold (at room temperature) 



If there are loose fasteners, re-torque them to the specified torque following the specified tightening sequence. Refer to the Torque and Locking Agent section of the General Information chapter for torque specification. For each fastener, first loosen it by ½ turn, then tighten in. If cotter pins are damaged, replace them with new ones. 344

Before lubricating each part, clean off any rusty spots with rust remover and wipe off any grease, oil, dirt, or grime. Lubricate the points listed below with indicated lubricant in accordance with the Periodic Maintenance Chart.

345

Note: Whenever the vehicle has been operated under wet or rainy conditions, or especially after a high pressure spray water, perform the general lubrication. Chain: Lubricate with Heavy Oil Pivots: Lubricate with Motor Oil Side Stand Clutch Lever Brake Pedal Rear Brake Rod Joint Footpegs Cables: Lubricate with Cable Lubricant Throttle Cables   

Lubricate the cables by seeping oil between the cable and housing. While the cable is disconnected at both ends, the cable should move freely within the cable housing. If cable movement is not free after lubrication, if the cable is frayed, or if the cable housing is kinked, replace the cable. Points: Lubricate with Grease Throttle Inner Cable Lower Ends Choke Cable Lower Ends (Grease the lower part of the inner cable sparingly)
