Hello everyone, I am having a chronic problem with clutch plates breaking. The bike is a 2000 YZ125. In the past couple months, this bike has ruined 3 sets of clutch plates. The first set was EBC plates, the expensive racing ones, with the extra plate in it. I put those in the stock basket, and within a couple weeks I had a plate break, and of course, get ground up in the transmission. That made a mess, and after cleaning it out, I installed a new Hinson basket, along with a new stock hub and pressure plate and Barnett clutch plates. Once again, a couple weeks later, I had a plate break and get ground up. A week after that I had a waterpump seal go, so I dissassembled the tranny and cleaned all that gunk and metal out of there. I put the stock plates in the hinson basket (they were still within spec) and swore to myself I would go with stock clutches from now on. Well, this week I took apart the clutch, and once again, we have a broken plate. This one seems to have just broken, there is one big piece, about 5/6ths of the plate, one small broken piece, and one piece that got ground up, and is of course scattered across the bottom end. Whats going on here? I'm getting tired of cleaning metal out of the bottom end, and eventually some of it is going to ruin a bearing or something. The first set of plates, I assumed it was a worn basket, the second set I assumed was because of the quality of the barnett plates, but three sets in a row is just excessive. I cant figure out why they keep breaking on me, anyone have any ideas? Im trying to sell this bike sometime soon, so this problem needs to be fixed, what do I do?
