Harbor Freight 99cc predator engine

Hello fellow motard enthusiasts....

Has anyone ever thought about and or successfully built a motorized bike with one of these bad boy engines i found at harbor freight tools?

It has the correct shaft rotation on it the only thing i wonder about will it have the correct gearbox pattern for a 4G GB and could i possibly use the same 49 cc four stoke mounting plate? I do know ill probably most likely will need a specialized clutch possibly change the weights and or spirngs in the centrifugal clutch. and may need to do a little frame modification etc to fit her in their.

I doubt if that gearbox would work for many reasons.

How about this gearbox from AGK?
