I just had a new clutch installed. My King Cobra was shot. I went with a HD FMS-M-7560-A302N (veleo?) and FMS cast iron flywheel. I got it back after install and it feels nice until I hit about 5000 rpm. Then its not horrible vibration but its definitly a lot more vibration than there was before. Do you think it just wasn't installed well or is that what I got what I paid for?
