Get the hot duner 12 port from Jim, 35mm pwks,Boss intake,VF-3 reeds,Shearer in-frames, and a Adjustable timing plate.If you ride very little trails and alot of sand You could have him build you a 421 cub instead of the 12 port.
Either way you go, both set-ups are incredible.You might need an extra pair of underware after you ride either one also.
