Default Re: Has anyone considered trying using something like this?

the realities of this matter are actually a little more lame than we would all hope.
most miniature model engines either have almost no compression or have shockingly low max RPMs (or both) because the thermodynamics of metals do not scale as well as the mechanical principals that allow the engine to function. I.E. a miniature engine will run but not manage it's heat well.

so an engine like this would either not be able to propel the bike, or would melt shortly thereafter.

but screw logic, I say put an inter-cooler onto a 50cc V-Twin and get-er-done!
