49cc engine running on E85 fuel

This guy claims to be able to run his 49cc bike engine on E85 fuel, which is 85% ethanol and 15% gasoline.  Many people think that ethanol can ruin your engine, so I don't recommend trying this just yet unless you have an extra china girl to spare.  Supposedly you have to use a larger jet in your carb, and the guy in the video says he added Marvel Mystery Oil to the fuel.  It's not clear what kind of 2-stroke oil he's using, since I believe the only oil that will dissolve in ethanol is pure ester-based synthetic 2-stroke oil.  Whether or not it's really currently possible, I'd love to be able to run my 66cc engine on mostly ethanol!
