I bought an 09 over the summer and for my senior project I am turning it into a heavy modified race bike. I need some experts to tell me what I need to do to the engine, suspension, etc. Thanks a lot
I just bought a new Procircuit spark arrestor for my crf 230 and i was wondering how big of a hole i need to cut in the airbox and what to rejet the bike to. i live at about 3000 feet elevation but mostly ride in the nevada deserts and sometimes at about 1000 feet elevation. thanks
