No new clutch here.
Maybe next year if I start saving now. (That's a $2000 mod for me - Quaife, clutch, flywheel, & labor)
I have a couple new ideas for launching that may help out.
Putting back in the return spring so I don't getting any extra timing advance below 3500rpm.
Spring inserts in the rear to stop weight transfer.
Buckshot... Are you using the old frame rails to make them or just as a model to make them?
