No because I've wheelied the bike before so I know where it needs to be as far as speed. Ive picked it up in 1st 2nd and 3rd. Grayracer is definitely right about it not being a clutch slipping. If it was the clutch slipping it wouldnt keep going back into 5th when pinned. (Its a jolting sensation) I'm going to crack the case but I'd bet money I'm going to find a bent and scraped shift fork and gears with the dogs rounded off.
