i have a rotaional vibration... when i rev the car up the car lurches forward when clutch in and in gear. i have adjusted the master and it will be fine (still vibrating but not lurching) then in a couple days its back to lurching... i have the McLeod street twin and adjustable master... could i have warped the flywheel? i went to the track and all you could see behind me was clutch dust... i seen that and loaded her back up on the trailor and went home...
