Check www.poweroll.com , but boring, dome-top piston a good cam larger carb say off of a 250X or 300EX would be a good start. Decent Exhaust too

He want's to beef it up...in order to achieve this boring the cylinder and increasing the piston size would be a necessary factor in his equasion. along with carb, headwork, exhaust, and cam. invrease the volume of the cylinder + a better flowing head + more valve opening (bigger cam) = more power.
