Opinions twin disc clutches

[blageo23]

I have the quarter master twin. Only problem I have had is the bolts that hold the pressure plate together hit the fork. Bought a "modified" fork and still hit. Then took it apart and modified it myself and it still hit. Ended up buying new bolts and countersinking them. It's worked for me since. Never had an issue with shifting at higher rpm. But I don't beat too
Much on it.
