Well, I have a problem. The valves in my Honda CRF 230F are ticking really bad, and the guys said it costs $75!! I can learn for that much, and he wouldn't even get it done until next Wednesday. So I am going to try and fix them myself, but I don't know if I need any special tools or anything. Anybody every do this or have any idea how?? Please help cause I really want to ride this weekend.
