as for the lift kit it just makes the bike sit up a bit higher making it easyer to jump etc.

a lift kit>> Pti King CRF50 Sub Frame Lift Kit - Pit King - Pit Bike Parts

orite nice, i can probly build one at my ag college if thos c***s let me, they wont let me even build a ramp or down ramp or anything bar building a trailor. what i mean by classes is like u ride a thumpstar and i ride a xr50 so like do xr/crf/ttr 50's only 4 raceing n shit or can they be built into a thumpstar size bike purly 4 ramp jumps?
