Some friends and I went riding this weekend and a bearing failed in my trans. I'm pretty sure it's the bearing on the shaft that the clutch bolts to. It started makeing a bad sound so we headed back to camp. I took the clutch apart thinking that was it. I spun the clutch by hand when everything was loose. It made a horrable sound with clutch discs out and spinning buy hand. The shaft even moves in and out a little. I'm pretty sure it's those bearings locating that clutch shaft. The bearing was suspect when I put the case back together. I pinched some pennys and it cost me dollars. That's what I get. Tearing engine apart this week, damn.
