Didn't slip off the line, only if at highway speed, downshifted, and hit WOT. Think it was 16,500, or maybe 17,000 miles. If I never rode it hard, never would have been an issue.
Actually, the bullet pin doesn't even move the clutch itself, like an automobile clutch, it just relieves pressure on clutch pack. Thats why you get that "clunk" when you put it in gear. No pressure on it, but the plates are stuck together.
