what is your price range? and what are you looking for? My son races 125cc 4-stroked ATVs in MX and we are factory sporsored. I can tell you a ton of stuff to change or mod on these china engines. i need a price and actual ideas of what you want as well as auto, shifter (semi or manual) and so on.

well the roller showed up today and its going to need a frame and its it ruff shape. for an engine i am looking at like 500 depends on what the rest of the bike cost to build. looking for a manual shift engine
