Fitting instructions for 80cc bicycle engine
blue to black = about 340ohms; black to white = 2.3ohms
Do not operate engine without kill switch installed. It could result in personal injury if an emergency stop is required. The only other way of stopping the engine is by releasing the clutch lever with bike brakes on and engine at slowest idle - this is not recommended.
MAINTENANCE ROUTINE1. Clutch:a) Remove right side cover from engine.b) Place a small dab of grease at gear mesh area.c) Replace cover.2. CarburetorDepending on riding conditions, clean air filter every 5 to 20 hours of operation by removing the filter cover to access the screen and element. Wash element with a degreasing agent. Be sure element is completely dry before re-assembly.3. Spark PlugRemove spark plug and inspect for excess carbon build up. Clean, re-gap to .6mm - .7mm if necessary. Check plug after every 20 hours of operation. A suitable replacement plug an NGK B6HS; NGK B5HS or BOSCH WR 7AC or Champion equivalent is okay to use. The NGK R7-HS is also recommended for better performance and smoother idling.4. Exhaust systemAfter 20 hours of operation check exhaust pipe for excessive oil and carbon build-up. Be sure to use supplied support strap to secure exhaust muffler to a solid anchor point on bike frame or engine.a) Remove exhaust pipe cap by loosening the retaining screw.b) Spray degreaser into baffle rinse and dry.c) Re-assembleNOTE: Excessive periods of low speed operation, idling or leaving fuel petcock in the “on” position during shut down periods may cause the pipe to become clogged with unburned fuel.5. ChainEvery time bike is ridden check the tension of the drive chain by:a) Rolling to bicycle forward to remove slack from the bottom of the chain.b) Find the center and push downward on the top of chain while measuring the deflection.c) Tighten chain if deflection is more than 15mm.d) Low speed "chain rattle" can be eliminated with the application of graphite grease to chain.6. Head BoltsTighten all fasteners after each five hours of operation. It's most important to check cylinder head bolts: tighten in a X pattern to 12 ft/lb. using a torque wrench. A two piece cylinder and head design engine requires head bolts be kept tight. Important: Check head bolts before each and every ride, vibration can cause them to loosen and blow a head gasket. Caution: Do not over torque or head bolts may break off. Use of a little 'Holdtite' or 'Locktite' is recommended to keep head nuts secured against vibration.7. Right side gearsRemove cover plate and apply a small amount of heavy grease on gear train. Do not over grease as leaks will occur and also may adversely affect clutch operation. Regular greasing if required will help reduce gear wear and keep gear train quiet.
