Are you still interested in any of this stuff? Those guys have been on my case because I've been a bit of a pack rat lately.
Anyway, I found out that the one good engine I have is actually a CB500T. That's the one that needs the shifter shaft replaced (I have a spare). Both 450 engines are locked up and need to be rebuilt. If you want, you are welcome to the 500 and any of the other 450 stuff I have at the price we discussed. All I'm keeping for myself is and a frame and one of the seized engines.
