Found this Chain Drive used with a Mazda 13B Rotary in a Jet Ski, is their
a limit on the RPM Chain Drive and Belt Drives can run at, does not look
like much gear reduction here.

I noted that in another email it was mentioned that the Maverick Flying Car
was FAA approved LSA, they are using a Subaru Engine, I was not aware that
Subaru engines where FAA Certified, the more I read and see the more
confused I am with this Light Sport Aircraft category?  Why wouldn't a
Mazda Engine be Certified if someone used one in a Special Light Sport
Aircraft Airworthiness Application...
