Pushrod? What the heck was it?

I've owned a few bikes over the years, and even the one that was older than I am didn't have a pushrod engine.

Cam timing/overlap, gearing, fuel delivery system, # of engine strokes, and engine size each have a notable effect on efficiency.

If you want MPGs, you need something that suits the use you'll be putting it to best, and for us to make suggestions we need to know what/how you'll be using it...otherwise if it's purely about MPGs, a decent bicycle with a 4-stroke weed-eater engine will get you 200mpgs; But I don't think that's what you're looking for.
