I have an 07 with 23,000 miles. I replaced the clutch diaphragm, removed the 1/2 clutch pad and hardware. I installed a Yamaha full sized clutch plate in it's place. When I'm starting out from a stand still, the clutch "pulses". Like it's grabbing and releasing, especially when it's cold. I've taken the clutch apart and verified the thickness of my original plates, and everything is within spec, like brand new. I installed the original pad and hardware, removing the full size pad. The pulsing is gone. I'm guessing it's the new clutch plate. Has anyone else run into this? I'm considering replacing all the clutch plates. Thoughts?
