Damn auto correct.... staking... not stalking. Edited above.
Lycoming has a procedure they call "staking the valve." ...
Nice thing about the XS650 engine design is with the exhaust valves easy to access at the front all you would need to do is remove the two covers and smack the top of the rocker arm. Trick on any engine is getting it right on TDC so engine won't turn from the pressure on piston.Lycoming has a procedure they call "staking the valve." for carbon buildup. Bring it to TDC, put 80 pounds of air in it, lay a piece of wood on the tip of the valve stem and smack hell out of it about a half dozen times. I've cleaned up many a carboned exhaust valve "staking" it.
From what 5twins said they would work with the correct keepers.I found some info on EBay when I was trying to verify that info for you. Maybe this will help?

It’s too bad this couldn’t be some simple fix for you, but I will enjoy following along with your work!
Not really difficulties. Just part of working on engines. When I bought the parts bike I knew I was buying a pig in the poke. I guess the pig is poking me. This is the first time I've rebuilt a engine since 1992. Kind of fun. Last engine was a 454 in a Camaro.
I am not enjoying your difficulties GLJ, but am certainly enjoying this whole discussion.

At least the XS650 is a bit easier to lift up on the work bench by one's self!This is the first time I've rebuilt a engine since 1992. Kind of fun. Last engine was a 454 in a Camaro.
650 was more work. had to muscle it out of the frame and the 6 inches onto the lift. With the 454 I had a full shop. Cherry picker, engine stand. You did not try to muscle a big block. Or small block for that matter.At least the XS650 is a bit easier to lift up on the work bench by one's self!
