80 CB750F
I'm having the same problem, when I really get ON it. I put a new/old clutch in it. What I mean by that is, someone on Ebay had an old, brand new in the bag, Barnett friction disks set on their shelf.
Must've been from the 80's. So, I'm wondering if this old cork clutch set doesn't like the semi-synthetic oil or something.
Is there a 'break-in' period for clutches?
Pressure plates looked good, still had texture to them. Replaced springs also.
