ok i talked to him (the shop manager) yesterday, and he says they didn't even have to adjust the valve clearances, they were all within specs. the mech insists that he only took the valve cover off, not the cam chain. he did say that he checked the chain to make sure it had the right amount of tension, and it did. not sure how he did this as i can't find any specs for cam chain tension in the manual. he said sometimes they end up putting on a manual chain tensioner, but did not have to on mine.
maybe when the mechaninc test drove it (i witnessed him giving it hell) and it jumped out of second gear, it revved up too quickly and some valve bounce occured, damaging one or more valves...
also, he showed me the dyno charts which show it running lean, especially up to 5k rpms. he thinks this is causing poor performance. i'm running a muzzys (w no exhaust valve) and a k&n filter. but that's the same setup i've had the whole time. he swears the pc will fix everything (cept the trans problem). i guess we'll see... he's already ordered one which should be in today. whether i agree to pay for it is a different story.
as for the clutch, he told me that it was probly the trans (gear dogs and/or shift forks) before he ever changed the clutch. the clutch was worn and needed replacing, so we tried that first hoping that it would correct.
thanks for your support guys.
