Thanks, it usually doesn't smoke but on occasion it does. I wonder if the ring gaps walk around and sometimes line up? It's on the center now, actually easier to center it then most of the cb750's. She's still a cold blooded old girl but like most of us old timers once going it goes pretty good.
It was in the 70's today, I can't believe I set up a deer feeder, played Santa Claus, worked on a K0 but didn't ride anything.
