I have a 2001 WR250f that has some scoring on the camshaft race. The service mgr. at the repair shop that I took it to tells me I need a whole new head. Looking around the different internet OEM parts houses I can get one for between $400 and $600 depending on where you look. he wants much more plus labor and possible replacement of the valves, guides, etc. Is there an alternative to buying a new cylinder head? Can it be reconditioned for much less? Any information would be greatly appreciated. Thanks.
