    i'm looking for some yoshi valve colletts for a gs1000r i'm putting back together, maybe someone has enough for one or two valves in their spares?

      Put up a pic Spyda. Showing valve stem dia - and where the raised ring comes on the inside.

            So looking at the valve groove, it's a single step collet. No raised ring like later stuff, just an internal step like a British product.

            I've made that type of collet for quite a few motors, it's not hard. I'd do them for you but the condition I'm in at present I don't trust myself on the lathe.
            Got someone local to you - or Neville Mickelson ?

            Waiting for a triple bypass - and not happy....
