The owner was happy with the way it felt and took it home. The interesting thing I found out during my troubles is that the clutch basket floats on a boss and is not made to lock in position. The drive chain from the crankshaft goes around the sprocket on the basket so any sideways forces exerted by the drive chain could cause the basket to float when the clutch is disengaged causing inconsistent gap between the plates. This is just a theory of mine so don't take it as gospel truth.

Glad the owner is happy with it. Hope he keeps up on the maintenance.

As for the clutch float - sounds about right.

Glad you worked out the problems. I was going to suggest that you reffer to the originally specified oil.

Back about 79 a friend had a Kawasaki 1000LTD that I subsequently bought from him. It ran a wet clutch. Thinking to treat his bike right my friend tried using Valvoline racing oil in the crankcase. After the oil change the bike would not move! The clutch just sat and slipped.

To fix the problem we had to totally dissasemble the clutch and rinse each plate with gasoline. Put regular (Castrol 20W50) oil in bike and everything was fine again. Just something for others to keep in mind.

I had a 1970 Triumph Bonneville and the clutch was slipping when I bought it as well as having the drag that you described. I found that the steel spacer plates were not flat from new. They are made from stamped steel. I took a few hours and with a machined steel flat plate and a small ball peen hammer. I was able to make them dead flat with no hammer damage to the plates. I checked the friction plates and they were all flat.
When all the plates were installed in the basket and the springs and cover on, I balance the spring tension by holding the clutch lever in and use the kick starter to turn the clutch pack. I watch the cover as it is turning and adjust the three springs until the cover spins straight. The clutch works smooth, easy gear engagement from neutral and NO slipping with a light clutch lever.
