Sure. I have built 3 MBs, all powered by Subaru Robin EHO35 engines. #1 is a Staton friction drive, #2 was a Staton rack mount chain drive, #3 is a GEBE belt drive. I'd be happy to be of help.
I would be more than happy to help you out as well! lost track of the builds but been in the industry of gas bike motors now for 6-7 years now? Where has the time gone? Good luck with your project and let us know how it goes!
