hey guys, I'm pretty new around here, I've got an 81 tomos silver bullet that I just finished rebuilding back to stock, and I just picked up a couple more bullets that I want to start doing some performance stuff on...question, on the a3 I know that Ill need to bore that rod to fit a 12mm wrist pin, but what else would I need to do or buy to have a fun/quick little scoot. I guess I'm just trying to find recomendations for kit, pipe, and intake/carb. and advice would be great thanks, what combinations do you guys have experience with?
