i have wiseco piston but they are the stock size, i have reeds but cant remember what kind, dmc exhaust, twin air filter. and that is it for motor mods. i took the top end apart today and the right piston has a small gouge on the side and bunch of dents and crap on the top of the dome. also the cylinder is a little scratched. so i think i found my problem. are any of you guys from the rapid city area to tell me were i can get my banshee machined so i can get the scratches out.
