Now what? How much is this gonna cost me ? what parts should I look into replacing once the head is off? I have'nt put my nose in the manual about this yet. This is Not what i was wanting to have to do .. and its looking like my fall riding will be a no go. Oh well, the project is so much more fun....... I tried this..http://www.xs650.com/forum/showthread.php?t=11693.. but did'nt work.. the valve still looked like crap just a little less charcoaled when i was done scrubbing it.. . i'll take a pic of it later for someones evaluation.
