hey guys, just picked up a 49cc R3 china pocket bike. was going to get a c2 water cooled but since its my first race bike project i thought id do an air cooled bike first to get the hang of things. i really want to turn this bike into a race bike, just a few questions, any welding required to the frame? im 180lbs and the frame kind of scares me could use some supports?, what 49cc parts would fit this bike? i plan on rebuilding the motor with new seals and gaskets, new clutch, sprockets, bigger carb, slicks, exhaust, also are hydraulic brakes a must? these disk brakes kind of suck. anyways thanks inadvace for any help/info you can give me!
