Bad vibrations on clutch release
Mcleod street twin with zf6.
McLeod Street Twin 64023 00 07
Have previously ran one before, I know they're grabby.
Car has been off road for 4.5 + years. Now back on road, new engine, new clutch, new zf from corvettenutz.
Now car has bad vibration upon clutch release. I never had this problem before. I'm talking about every gear, upshift and downshift. Clutch pedal feels fine.
Could it have been improperly aligned?

It only has bad vibration at the instance of the clutch release. It has no more vibrations throughout the rpm range.
Could it be a balance issue if it doesn't happen throughout rpm range?

There are a number of things that can cause clutch chatter; a few among them is an improperly surfaced or warped flywheel, grease or oil on the clutch disk, warped clutch disk, bad pilot bushing/bearing, misalignment of the motor-bellhousing-transmission, worn or bent clutch fork, bent transmission input shaft, clutch disk needing to break-in...

I dropped the transmission, and pulled the clutch.
Took some pictures and sent to McLeod, who then told me to mail it back to them for their techs to inspect.
It goes out on Monday.
Cost me like $105 cuz they never emailed me a return label. I'll see if I get reimbursed or not after they inspect it.

I'm sure it's possible if enough heat is introduced. This is exactly why we use a Billet Steel Flywheel which is zero balanced along with our pressure plates. By the time you have your stock flywheel resurfaced and the assembly rebalanced our kits more than pay for themselves. Hope you get yours working right.
