4.4. Chain
Lube the chain every race by spraying chain lube on
the chain while manually rotating the rear wheel.
To replace the chain, loosen the engine and slide it
back to release the old chain from the sprocket.
Reverse the procedure after installing a new chain.
4.5. Throttle Cable
Lubricate the throttle cable each time the engine is
run. Also check, and adjust the cable as needed, to
assure the correct throttle and that the throttle
returns properly and opens full size.
If the cable frays, it must be replaced.
4.6. Carburettor
Cleaning:
Fuel and oil may contain impurities,
and/or residues.
1. Take the intake silencer off the carburettor by
unscrewing the clamp.
2. Disconnect the throttle cable from the carburettor.
3. Take the carburettor off the engine and open the
float chamber by unscrewing the five screws. Clean
the parts, openings and passages with compressed air.
Check the float chamber gaskets and eventually
change them if damaged.
4. Close the float chamber by screwing the five screws
and replace the carburettor in the engine.
5. Clean the inside of the intake silencer.
6. Attach the intake silencer assembly to the adaptor.
7. Tighten it with the specific clamp. Wrong assembly
will cause the loss of the intake silencer.
4.7. Spark Plug
Cleaning:
Oils produce carbon deposits or
residues that make necessary the spark
plug to be checked and cleaned, at
least every 5 hours.
Unplug the spark plug and clean it by using a brass
metal brush.
Setting Plug Gap: Use a specific spark plug gap gauge to set up correct
gap. Correct gap: 0.8 mm.
