Turned out good, so mine should work too.

You can adjust cut saddle to however thick you want. The thinner you make it the closer the engine gets to seat post and increasing the need for the offset intake manifold for carburetor clearance.
I still almost always cut a 1/4 inch off just so I can drop the motor some.

You can fine tune the thickness of the saddle to eliminate any chain tension-er. I also use shims I get from one of the vendors on the site to also adjust the drive chain as needed.

Looks like it should work then. I'll be getting a motor for it soon so I'll see how it goes.

Hopefully these will not be too hard to cut to size.

You just want to make a straight cut. If you square it up in the vice you can let a hack saw follow the top of the vice jaws an then use a file to touch up the edges. If you don't have a vice find a friend who does. Only takes a few minutes to do.

When you get the motor you can try it without cutting the saddle. If you have clearance then just leave it stock.
