Ok, I've bled the clutch twice, the problem still existed, so I had it done at the shop. It is still doing the same thing, the shop recommends rebuilding the master cylinder, but the trouble only occurs when the bike gets hot. Then I have to pump the clutch to get it to disengage. If it's only when its hot, how could that spell master cylinder, seems the heat is localized to the slave cylinder area and the clutch mechanism itself. Perhaps I should replace the slave sylinder. Or have it rebuilt. Or maybe I should have both rebuilt? Any comments? Mike
