    Ive been thinking of lighting the crank for higher rpms. What do you guys think? The material lost will be filled up with lighter material.

    Why not try doing it as an experiment and see how much extra rpm you can get out of the engine.

    We lighten the cranks and flywheels on "real" engines so they rev faster.
    You won't gain any rpm it just gets there quicker. The reduced weight will also make it harder for the engine to idle.

    @ TOTAL_CARNAGE,

    Have to confirm what you said:
    because after installing my centrifugal clutch, the engine idled quite a bit better, even when idle speed was reduced.
