I have a 2006 CRF450R. I purchased it about 4 months ago and have ridden it a dozen or so times. The last time I rode I punched a hole in the clutch cover with the brake pedal and used JB weld as a temp repair. I took the cover off today to replace it and found the bike has a Barnett clutch basket in it. I also noticed the clutch basket was rubbing on the engine cover. It looks like the basket has excessive wobble allowing it to move far enough to rub. Any ideas as to what might be causing this? Ideas how to fix? I thought it might need a new bearing (needle bearing) but I don't want to purchase and put back together only to find it didn't fix the problem. Also, does anyone know anything about the Barnett clutches. The one I have has 300419 stamped inside the clutch basket. It has what looks like aluminum tabs riveted onto the fins. One of the tabs appears to be missing, others are loose. Lord know where the missing one might have ended up. Any ideas where to check? I can't see any evidence of it when I pulled the engine cover off and the bike runs fine. Any help is much appreciated.
