from what i can gather, he wants some help picking parts. what parts to buy and what company is best to go with. to answer some of it, yes the chariot is a good head to go with. As far as getting a new crank and pistons just get the 4 mm stroker kit. then you need some carbs and a good set of pipes, t5, cpi, or shearer. of course this all depends on what type of riding you plan on doing with it. and of course dont forget about the suspension. maybe extended a arms better shocks, extended swingarm. there is an entire list of things that can be done.
