GENERAL INFORMATION GENERAL SAFETY 1-1 SERVICE RULES 1-2 MODEL IDENTIFICATION 1-3 SPECIFICATIONS 1-4 TORQUE VALUES 1-12 GENERAL SAFETY CARBON MONOXIDE r lf the engine must be running to do some work, make ~re the area is well vent ilated. Never run the engine in an "-· Jclosed area. r The exhaust contains poisonous carbon monoxide gas · "\.at can cause loss of consciousness and may lead to ' death. Run the eng ine in an open area or with an exhaust evacuation system in an enclosed area. GASOLINE Work in a well ventilated area. Keep cigarettes, flames or sparks away from the work area or where gasoline is stored. Gasoline is extremely flammable and is explosive under certain conditions. KEEP OUT OF REACH OF CHILDREN. T COMPONENTS ( Engine and exhaust system parts become very hot and " "mai n hot for some time after the engine is run. Wear { ) sulated gloves or wait until the engine and exhaust system have cooled before handling these p art s. USED ENGINE OIL Used engine oil may cause ski n cancer if repeatedly left in contact with the skin for prolonged periods. Although this is unlikely unless you handle used oil on a daily basis, it is still advisable to thoroughly wash your hands with soap and water as soon as possible after handling used oil. KEEP OUT OF REACH OF CHILDREN. TOOLS LUBRICATION & SEAL POINTS CABLE & HARNESS ROUTING EMISSION CONTROL SYSTEM BRAKE DUST 1-16 1- 18. 1-20 1-23 Never use an air hose or dry brush to clean the brake assemblies. Inhaled asbestos fibers have been found to cause respiratory disease and cancer. BRAKE FLUID CAUTION: Spilling fluid on painted, plastic or rubber parts will damage them. Place a clean shop towel over these parts whenever the system is serviced. KEEP OUT OF REACH OF CHILDREN. NITROGEN PRESSURE For shock absorber with a gas-filled reservoir: • Use only nitrogen to pressurize the shock absorber. The use of an unstable gas can cause a fire or explosion resulting in serious injury. • The shock absorber contains nitrogen under high pressure. Allowing fire or heat near the shock absorber could lead to an explosion that could result in serious injury . • Failure to release the pressure from a shock absorber before disposing of it may lead to a possible explosion and serious injury if it is heated or pierced. 1-1

GENERAL INFORMATION COOLANT Under some conditions, the ethylene glycol in engine coolant is combustible and its flame is not visible. If the ethylene glycol does ignite, you will not see any flame, but you can be burned. •Avoid spilling engine coolant on the exhaust system or engine parts. They may be hot enough to cause the coolant to ignite and burn without a visible flame. • Coolant (ethylene glycol} can cause some skin irritation and is poisonous if swallowed. KEEP OUT OF REACH OF CHILDREN. • Do not remove the radiator cap when the engine is hot. The coolant is under pressure and could scald you. ( ~UTION: ' / ' Using coolant with silicate corrosion inhibitors may cause premature wear of water pump seals or blockage of radiator passages. - Using tap water may cause engine damage. l l · .._,/ If it contacts your skin, wash the affected areas immediately with soap and water. If it contacts your eyes, flush them thoroughly with fresh water and get immediate medical attention. If it is swallowed, the victim must be forced to vomit, then rinse mouth and throat with fresh water before obtaining medical attetion. Because of these dangers, always keep from the reach of children. Recycle used coolant in an ecologically correct manner. SERVICE RULES 1. Use genuine HONDA or HONDA-recommended parts and lubricants or their equivalents. Parts that don't meet HONDA's design specifications may cause damage to the motorcycle. 2. Use the special tools designed for this product to avoid damage and incorrect assembly. ?· Use only metric tools when servicing the motorcycle. Metric bolts, nuts and screws are not interchangeable with English 'lsteners. · ..... nstall new gaskets, 0-rings, cotter pins, and lock plates when reassembling. · 5. When tightening bolts or nuts, begin with the larger diameter or inner bolt first. Then tighten to the specified torque diagonally in incremental steps unless a particular sequence is specified. 6. Clean parts in cleaning solvent upon disassembly. Lubricate any sliding surfaces before reassembly. r-ie-tt er reassembly, check all parts for proper installation and operation. :.: _) oute all electrical wires as show on pages 1-20 through 1-22, Cable and Harness Routing. 1-2
