Dennis,
The Kaw and Yammers use the same size, 29mm diameter, we use.
Shim kits here!
Be sure the engine is stone cold when you do the measurements too. You may luck out and either not need any, or swap some around to get the right gap.
On my site I have a neat little
shim calculator program too, it will tell you what size you need to order to get the required gap.
