Looks nice. I am having clutch trouble myself and don't know what to do. I had the pressure plate( original three finger style from Shoe Box Central) clutch disk, throw out bearing and pilot bearing. This is on a 50 model. I had bad clutch shudder before and after having everything replaced. Wish I would have bought. Billett flywheel and diaphragm pressure plate.
Looks nice what you made.
a 11" centrifugal/ original type clutch is fine as long as you don't try and drag with it lol, they have a nasty tendency to not want to release at RPMs above 4000, it can get hard on the ******. That would be one reason I could think of.
Diaphragm clutches tend to take less pedal pressure to actuate than long clutches. This is especially true in higher performance applications running at higher RPMs.
