Please help....Hadn't been on bike in awhile...now the clutch is not releasing?Clutch lever and slave cylinder seem fine...I bled them just in case and thru the oil fill hole you can see the clutch pack separating almost 3/16-1/4 in-which seems fine. The service dept said probably clutch discs just froze together and won't release and to try jarring them loose so I've tried running it on the center stand in various gears and slamming on the rear brake briefly but nothing yet. Service guy said unlikely for it to be a warped clutch plate since it worked fine when I parked it.Anybody have any ideas? thanks in advance.
