I replaced my starter clutch this time last year with OEM replacement parts and had no more problems for the rest of the season. I rode all year and put it away last fall and all was fine it seemed. So this year the only motor work I've done is to replace my main clutch friction plates. They were brand new Barnetts and I only presoaked them minimally for about 30 minutes a couple of days ago. Last night I was doing an oil change and went to start the bike to top off the oil level and the mother wouldn't start. Turning over good but clutch pack not engaging. I took the cover off and verified that. All gears are fine. They engage the large gear on the back of the rotor correctly and it only spins (by hand) in the one correct direction as it's supposed to. The ends of the pack mounting bolts are protruding through the rotor and look tight. It's gotta be the little spring loaded pucks not spinning out and grabbing? What else is there? And being one season old OEM parts why would they be failing so soon and out of the blue? I'm stumped for answers. I'm getting ready to pop off the rotor next. But wanted to run this puzzle past you guys first for ideas. Could the new main clutch plates I installed with a possible stiction problem hang up the system and contribute to this problem?? I'm stumped and pissed off. A bad combination. Any suggestions would be appreciated. Thanks guys.
