Thanks! I currently have a couple ideas floating around in my head, either take my current bike, Roadmaster Adventures 700, and swap out the 18-speed pedal gearbox with an engine and 3 gears, or do a little minichopper build out of a stingray, using the same combo.
Engine being looked into is a GX35 OHC 35cc 4-stroke motor and a three-speed trannie, friction-plate clutch if possible or practical, and a mod I'm particularly interested in is the EFI kit for the engine from Ecotrons.

Also, Honda may say not to operate the engine with the cover removed, due to injuries from moving parts (cam gear is covered) or burns from muffler (would be replaced with a straight-pipe going to the rear wheel), but it would look much cooler on the frame without the cover, IMO, particularly with the stock tank replaced with an on-frame or in-frame tank.
And as for the Roadmaster that may get a moped conversion, the stock paint would be sanded off, and it would be painted rattle-can black, which would look cooler than the stock paint and decals.
In addition, I wonder if turbocharging the little 4-stroke would be too much on it or not, after it's been fuel-injected of course.
