.......because it has the aerodynamics of a barn door, a tailgate that acts like a NA$CAR spoiler and a 5.88 set of rear gears maybe??

Heck, my V10 F350 only does 10-12 around town And it must have every smog control device known to man on it!!

I'm considering building a car with a motorcycle engine and lots of lightweight stuff like a tube frame, etc. With gas getting nuts it would be cool to have a little driver that got really good gas milage. I know squat about motorcycles though, so if and when I decide to do it I'll need some input from the bikers among us to help pick one with the right cc's and all to use as a donor.

I'd just buy a moped, but with some of the drivers we have down here I at least want SOME protection around me.

Why not a little ricer 4 cyl engine - some of them will do even better then many bike motors

Good thought. I just assumed mc engines like the 750 cc ones would get fantastic milage. But you may have a good point, and the ricers run forever and are cheap. especially wrecked ones.

A number of years ago there was an outfit in, I think, Reno NV that made a T bucket kit that took any one of a variety of 4 cyl motorcycle engines. It was roughly a 3/4 maybe 7/8 scale car. I suspect market demand didn't support their long term existence. It's all about hp and weight in this context so I don't know that the motorcycle engine would have any particular advantage if there were a comparable small car engine (Aveo, Fit, and so on).

That ratio surprises me - my father in law had a '79 Chevy 2500 with a 350. If I recall, the final ratio and with a granny geared trans was in the 4.50 range and his mileage was horrible - like what you are getting. But by then in his life he only drove it 2 miles for coffee or 15 miles to my house to help me on my additions so it really didn't matter.
