Broken clutch basket and Rekluse...

I put in a z-start in my 450 about 5 or 6 rides ago and everything was working great. I checked the gap after about an hour and everything was in spec. This weekend the bike locked up on the track after some noise from the clutch area. I took the cover off last night and found a broken tab from the outer clutch basket wedged between the case and the clutch. One of the fiber plates was broken in about 8 pieces and there was excessive wear on the fingers of the basket that was not there 5 engine hours prior to the damage. There was never any warning or loss of clutch action before the failure. Any idea what could have caused this type of problem?

have you ever taken off the basket? is it OE? :thumbsup:

which fiber plate was it? (assuming #1 is closest to the engine)

Basket is OE and it has been off before. It was either the second or the third fiber from the engine.

Stumpy, step 14 of your installation instructions emphasizes a very important step. " The outer tabs of the pressure plate rest in the same clutch basket windows that the outer tabs of the friction disks do". If somehow you made an error and did not get this right, this most likely was the reason your basket cracked. This has happened to other models in the past, that's why it's emphasized in the instructions.

That was not the problem.
