1. Clutch: 

 a) Remove right side cover from engine. 

 b) Place a small dab of grease at gear mesh area. 

c) Replace cover. 


Depending on dusty 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 Plug: 

Remove 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 is NGK BP-6L if you can find it. Otherwise, go for the NGK B-6L. The NGK R7-HS is also recommended for better performance and smoother idling.

4. Exhaust system: 

After 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) Pull cap and baffle out of pipe. 

c) Clean with degreaser, rinse and dry. 

d) Re-assemble. 

★★★NOTE: 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. Chain: 

Every 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 Bolts: 

Tighten 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. 

7. Right side gears: 

Remove cover plate and keep 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.
