Nice thing about the clutch is you can access without draining oil. Just be sure it's on the sidestand.
It's possible how full is the master resistor. If it's to full it can hydroloc.I did change the oil (Used Honda oil and filter)
I did bleed the clutch, it feels good. The bike when idling went in and out of gear. Is it possible the clutch is not totally disengaging?
Second the dry plates"I will check the master cylinder for level and return port, if good I will open her up and check springs."
I also suspect something other than wear. Don't just check springs,check the plates.But my first suspect is clutch not fully releasing.
I would pull the slave cylinder off,pull the lever,which will push out the piston,then push it back in by hand.If that seems normal, I'd bleed it again.
Clutches wear slowly and can still be ridden under normal load when the plates are down to minimum allowed thickness,so the way it behaved for you tells me it shouldn't be worn, however if this was the first ride and it wasn't ridden last year after 12 yrs in storage, I would suspect the plates have dried out and need to be soaked in oil.
