INTRODUCTION ^^`, ` s This manual is designed primarily for use by trained technicians in a properly equipped workshop. However, it contains enough detail and basic information to make it useful to the owner who desires to pe rf orm his own basic maintenance and repair work. The work can only be carried out if the owner has the necessa ry hand and special service tools to complete the job. A basic knowledge of mechanics, including the proper use of tools and workshop procedures is necessary in order to car ry out maintenance and repair work. satisfactorily. Whenever the owner has insufficient experience or doubts his ability to do the work, all adjustments, maintenance, and repair work must be unde rt aken by an authorised Triumph Dealer. In order to perform'the ' work efficiently and to avoid costly mistakes, read the text and thoroughly familiarise yourself with procedures before sta rt ing work. All work should be performed with great care and in a clean working area with adequate lighting. Always use the correct special service tools or equipment specified. Under no circumstances use makeshift tools or equipment since the use of substitutes may adversely affect safe operation. Where accurate measurements are required, they can only be made using calibrated, precision instruments. For the duration of the warranty period, all repairs and scheduled maintenance must be performed by an authorised Triumph Dealer. To maximise the life of your Motorcycle: Accurately follow the maintenance requirements of the Periodic Maintenance Chart in the Service Manual. Do not allow problems to develop. Investigate unusual noises and changes in the riding characteristics of the motorcycle. Rectify all problems as soon as possible (immediately if safety related). Use only Triumph Motorcycle Parts as listed in the parts catalogue/parts microfiche. Follow the procedures in this manual carefully and do not take short cuts. Keep complete records of maintenance and repair with dates and any new parts installed. Use only approved lubricants, as specified in the Owner's Handbook, in the maintenance of the motorcycle.

INTRODUCTION ASBESTOS REFERENCES This warning may apply to References any of the following KST components or any References to the left-hand or right-hand side given in assembly containing one or this manual are made when viewing the motorcycle more of components:- from the rear. WARNING CONTAINS Brake Shoes or Pads Operations covered in this manual do not always ASBESTOS Clutch Friction Material include reference to testing the motorcycle after repair. Breathing asbestos Gaskets It is essential that work is inspected and tested after dust to healtthrous Insulators completion and if necessary a road test of the motorcycle is carried out particularly where safety Follow safety instructions I related items are concerned. SAFETY INSTRUCTIONS • Operate if possible out of doors or in a well ventilated place. • Preferably use hand tools or low speed tools equipped with an appropriate dust extraction facility. • Dampen dust and place in a properly closed receptacle. Dispose of the closed receptacle safely. • Never use an airline to blow dust from components TAMPERING WITH NOISE CONTROL SYSTEM PROHIBITED Owners are warned that the law may prohibit: (a) 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; and (b) the use of the vehicle after such device or element of design has been removed or rendered inoperative by any person. Dimensions The dimensions quoted are to design engineering specification with service limits where applicable. During the period of running-in from new, certain adjustments may vary from the specification figures given in this manual. These will be reset by the Dealer at the After Sales Service, and thereafter should be maintained at the figures specified in this manual. REPAIRS AND REPLACEMENTS Before removal and disassembly, thoroughly clean the motorcycle. Any dirt entering the engine or other parts will work as an abrasive and shorten the life of the motorcycle. Particular attention should be paid when installing a new part, that any dust or metal filings are cleared from the immediate area. 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. Never lever a component as this will cause damage both to the component itself and to the surface being levered against. Whenever tapping to aid removal of an item is necessary, tap lightly using a hide or plastic faced mallet.

INTRODUCTION Edges Watch for sharp edges, especially during engine disassembly and assembly. Protect the hands with industrial quality gloves when lifting the engine or turning it over. When replacement parts are required, it is essential that only genuine Triumph parts are used. Safety features and corrosion prevention treatments embodied in the motorcycle may be impaired if other than genuine Triumph parts are fitted. In certain territories, legislation prohibits the fitting of parts not to the manufacturer's specification. Tightening procedure Generally, when installing a part with several bolts, nuts or screws, they should all be started in their holes and tightened to a snug fit, evenly and in a cross pattern. This is to avoid distortion of the part and/or causing gas or oil leakage. Conversely, bolts, nuts, or screws, should all be loosened (in sequence if specified) by about a quarter of turn and then removed. Where there is a tightening sequence specified in this Service Manual, the bolts, nuts, or screws must be tightened in the order and by the method indicated. Torque wrench setting figures given in this Manual must be observed. The torque tools used must be of accurate calibration. Locking devices, where specified, must be fitted. If the efficiency of a locking device is impaired during removal it must be renewed. This applies particularly to micro-encapsulated fixings which must always be replaced if disturbed. Where necessary, the text in this manual will indicate where such a fixing is used. iv

1 GENERAL INFORMATION T IGNITION SYSTEM SAFETY PRECAUTIONS WARNING: The ignition system produces extremely high voltages. Do not touch any part of the ignition system or any cables while the engine is running. An electric shock caused by contact with the ignition system may lead to illness, injury or death. WARNING: Wearers of surgically i mplanted heart pacemaker devices should not be in close proximity to ignition circuits and or diagnostic equipment. The ignition system and any diagnostic equipment may interrupt the normal operation of such devices causing illness or death. DANGEROUS SUBSTANCES WARNING: Many liquids and other substances used in motor vehicles are poisonous and should under no circumstances be consumed and should, as far as possible, be kept from contact with the skin. These substances among others include acid, anti-freeze, asbestos, brake fluid, fuel, lubricants, and various adhesives. Always pay close attention to the instructions printed on labels and obey the instructions contained within. These instructions are included for your safety and well being. NEVER DISREGARD THESE INSTRUCTIONS! fluoroelastomers WARNING: fluoroelastomer material is used in the manufacture of the valve stem oil seals in Triumph motorcycles. In fire conditions involving temperatures greater than 315°C this material will decompose and can then be potentially hazardous. Highly toxic and corrosive decomposition products, including hydrogen fluoride, carbonyl fluoride, fluorinated olefins and carbon monoxide can be generated and will be present in fumes from fires. In the presence of any water or humidity hydrogen fluoride may dissolve to form extremely corrosive liquid hydrofluoric acid. If such conditions exist, do not touch the material and avoid all skin contact. Skin contact with liquid or decomposition residues can cause painful and penetrating burns leading to permanent, Irreversible skin and tissue damage. ENGINE OILS WARNING: The oil may be hot to the Contact with hot oil may cause the skin to be scalded or burn ed. WARNING: Prolonged or repeated contact with engine oil can lead to skin dryness, irritation and dermatitis. In addition used engine oil contains potentially harmful contaminants which can cause cancer. Wear suitable clothing and avoid skin contact. Health Protection Precautions • Avoid prolonged and repeated contact with oils, particularly used engine oils. • Wear protective clothing, including impervious gloves where practicable. • Do not put oily rags in pockets. • Overalls must be cleaned regularly. Discard heavily soiled clothing and oil impregnated footwear. • First aid treatment should be obtained immediately for open cuts and wounds. Always be aware of who your nearest first aider is and where the medical facilities are kept. • Use barrier creams, applying before each work period to protect the skin from the effects of oil and grease and, to aid removal of the same after completing work. • Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed. • Do not use petrol, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin. • If skin disorders develop, obtain medical advice without delay. • Where practicable, degrease components prior to handling. A WARNING: Any risk of eye injury must be avoided. Always wear eye protection when using a hammer, air line, cleaning agent or where there is ANY risk of flying debris or chemical splashing 1.2

GENERAL INFORMATION 1 ENVIRONMENTAL PROTECTION PRECAUTIONS CAUTION: Do not pour oil on the ground, down sewers or drains, or into water courses. To prevent pollution of water courses etc., dispose of used oil sensibly. If in doubt contact your local authority. Burning of used engine oil in small space heaters or boilers can be recommended only for units of approved design. If in doubt check with the appropriate local authority and/or manufacturer of the approved appliance. Dispose of used oil and used filters through authorised waste disposal contractors, to licensed waste disposal sites, or to the waste oil reclamation trade. If in doubt, contact the Local Authority for advice on disposal facilities. BRAKES A WARNING: Brake fluid is hygroscopic which means it will absorb moisture from the air. The absorbed moisture will greatly reduce the boiling point of the brake fluid causing a reduction in braking efficiency. Replace brake fluid in line with the Periodic Maintenance chart. A dangerous riding condition could result if this important maintenance item is neglected! Do not spill brake fluid onto . any area of the bodywork as this will damage any painted or plastic surface. Always use new brake fluid from a sealed container and never use fluid from an unsealed container or from one which has been previously opened. Do not mix different brands of fluid. Check for fluid leakage around brake fittings, seals and joints. Check regularly for brake hose damage. FAILURE TO OBSERVE ANY OF THE ABOVE WARNINGS MAY REDUCE BRAKING EFFICIENCYi LEADING TO AN ACCIDENT. WARNING: If there has been an appreciable drop in the level of the fluid in either brake fluid reservoir, ' consult your authorized Triumph Dealer for advice before riding. If the brake lever or pedal feels soft when it is applied, or if the lever/pedal travel becomes excessive, there may be air in the brake lines or the brake may be defective. It is dangerous to operate the motorcycle under such conditions and remedial action must be taken by your authorized Triumph Dealer before riding the motorcycle. Failureto take remedial action may reduce braking efficiency leading to an accident. WARNING: Use only D.O.T. 4 specification brake fluid as listed in the general information section of this manual. The use of brake fluids other than those D.O.T. 4 fluids listed in the general information section may reduce the efficiency of the braking system leading to an accident. Failure to change the brake fluid at the interval specified in the periodic maintenance chart may reduce braking efficiency resulting in an accident. WARNING: Never use mineral based grease in any part of the braking system or in any area where contact with the braking system is possible. Mineral based grease will damage the hydraulic seals in the calipers and master cylinders. Damage caused by contact with mineral based grease may reduce braking efficiency resulting in an accident. 1.3
