Had some Briggs LO206 engine mounts made out of Billet 6061 T6 aluminum. 

It's made for a European frame with dimensions that are 32mm tube x 92mm center to center. The engine is offset so the sprocket is close to the bearing so there is clearance for the seat strut and larger seats. 

The air filter clears the tire by just over an inch, but varies based on tire size. 

Mounts come with the clamps. And are not assembled.
