Hey all. I have a 1972 CB350. Just recently the transmission has started slipping while I'm driving in 5th gear. It acts as if the clutch were being pulled in and released periodically despite not actuating the clutch. I have adjusted the clutch tension to where I feel confident that when the clutch is released there is no pressure pushing the plates apart. My question then is this. What are the chances that I just change out the clutch plates? What is the possibility that the actual transmission is failing? I would rather not change out the clutch plates only to find that I am still going to need to split the cases to replace the gears and shafts. The bike only has around 15k miles on it. It's hard to imagine that the transmission is failing but then again the same goes for the clutch plates at that point. Any insight/advice on this problem would be much appreciated. Thanks so much.
