lol james ,all depending what you want to happen if you want the bike to accelerate faster then put lighter rollers in it this makes the engine rev faster as it pulls away and stops it from gearing up as fast but if you go too light you can lose top end speed.a safe bet for a 50cc speedfight is 5 gram rollers mate.

heavy.the heavier the weight rollers the quiker the sentrifugal clutch engages.
