I started having an issue at the track over the weekend. Initially, I thought my clutch was slipping but after a quick once over I discovered the free play in the clutch lever was gone. So I readjusted it and road the rest of the weekend without an issue. But after getting home and checking it again, it appears to be getting too tight again. Shouldn't it be getting looser if the discs are wearing out? What would be causing this?
