Last summer I replaced the clutch disk pressure plate and spring disk. The throughout bearing plastic housing was oversize so I sanded it down to the specified diameter. The clutch spline was lubed. All worked just great then in Nov. I put the bike on the back of our motor home and came to Florida. I put about 500 miles on then left the bike back on the motor home and flew home . After 5 weeks I returned and started to use the bike again. The first short rides were ok then I took a 20 mile ride and the clutch did not release. When things cooled after 15 min. I heard the clutch snap back and then drove back. This continues to happen when thing get nice and warm. When the motor is cold the clutch operates very smoothly and as things get warmer it is harder to pull the clutch leaver and I can hear a grating noise.
My question : What is the solution to this problem. Is the plastic bearing holder a factor.
I would like to ride again soon.
