Running a Sparks clutch kit and have been getting a chattering/grinding noise on decal only between 25-30mph just before the clutch starts to free wheel. I have no loss in performance and there is no noise during accel. I have several hundred miles on it and it has made the noise since intalling the clutch kit. Ive taken both primary and secondary apart a couple times and can’t find anything wrong. The noise will not occur if ran on jack stands. Only while on the ground. Any ideas?
