I have one here not sure if it fits the H6 though. I'll post a pic and you can tell me if it's suitable

There's two types. One with a tape fit and the other a spline. It was around '78 they changed.

Honda XR fits, but they are flat. You either machine a new spacer or machine the existing one off your old sprocket. There's no need to weld the spacer to the flat sprocket, which makes it easier to replace down the track.
Cheers,

Hi guys thanks for the help, I did the machining bit a while back with a ducati I owned,if I can buy one outright, alot easier, its an 11 teeth on a spline. How do I get the pic lozza?

Machining sprocket seems a bit extreme to me. Check with Jared at SW Montesa but I'm pretty sure both are available at very reasonable prices.
