When I spin the rear axle by hand, if I go fast enough the clutch makes a loud noise then slams and turns the crank, even when I turn off the ignition on the stand after I had it on, it instantly makes the same noise then violently stops. Any ideas as to what this issue is and how to solve it? Thank you.
Clutch drum is probably gunked up. Or one of the clutch arms has cracked/failed and is throwing out prematurely.
Or the needle bearing needs cleaned/relubed/replaced.
Clutch drum needs pulled apart and serviced at a min every 2nd trip to the track. It’s easy and takes 5 min.
