Hello. I see that this is a common problem but I want to get some definitive advice. Problem is: Gear change is very tough. If you pump the clutch, it helps. No leaks around the clutch system. Fluid is full. The fork is releasing fully from what I can see. The pedal is only returning 3/4, just a little stiff at the top. Will bleeding the system help? Or have I over looked something here?
