Stability shouldn't be much of an issue - I won't be racing it, and the center of gravity would be pretty low. Besides, there's something else a 4th wheel adds: complexity. Driving a rear axle means I'd also need to use a differential, adding even more weight and design issues. I'd like to use the entire drive section from a light motorcycle. it keeps things light and simple, plus it would get me closer to a real teardrop shape.

They're far easier to re-gear using different sprockets, than adapting a CVT.
When adding a streamlined fairing, you'll need to re-gear the drivetrain to lower rpm @ your most used speeds.

Excellent point on the gearing. Looks like a 250cc motorcycle engine will be the ticket then.. anyone know of particular models that get good fuel economy?
