It's me gordon. Oh wait, I'm not supposed to see what you post!
I have not pulled the motor apart, however my shifts are very smooth. I have no clutch slip at all. My gears do not jump and neutral is very easy to get. Engine noise is very low aside from clutch rattle and even that is quite low.
I have been using it for a few years now and it has worked very well for me. I would be willing to bet that if I had to take the engine apart, it would look very good on the inside. I may do that this winter since 33 year old seals do sometimes need to be replaced.
