I had my clutch replaced 2 months ago and I was never happy with the job because I would usually get a slight chatter when the clutch engaged from a stop in first gear. I generally take off slowly and do not push it very hard. I sent it back once to have it checked and the mechanic told me that it was not a chatter but the engine running rough in the 1000 - 1500 rpm range and that what I was feeling was the roughness tranferring from the engine through the clutch. He was able to improve it somewhat but it was still there and bothered me. Today for the first time with this new clutch I pulled a hole shot and intentionally got some pretty good clutch slippage going. Lo and behold the chatter in nearly gone. I am thinking that the clutch plates were not aligned properly and I must have seated them in better. Is this possible?
