so i decided to get a big bore kit, which one do you guys recomend?should i buy one that has the big valve head,cams,carbs, or is the new piston and cylinder enough?
also if you can throw out some prices if you are selling the kits.

thanks

check out twobros.com they have so many options def go with at least an 88cc and i heard the big carb helps bunches too
