Well, i've been reading forums all day about the 250f's reliability, and let me just say that this subject has been beaten to death!!! However i'm still unclear on it. I want to stay with a honda...do some people just buy the bike from the factory as a lemon, or is their riding style a factor? I ride desert, mx, and trails... I don't ride like a bat out of hell. Would I be doing valve jobs every 5 minutes or what? also i've heard that PC valves solve the problem??? Never had a four-stroke before, let me know.
