lol. sounds like my rig on a good day. snap crackle and pop...pop....pop.

I'm "only" getting 85 mpg too. inefficient engine coupled to a single speed tranny is probably why.

I think otherwise a 49cc (like a fancy-smancy Honda Metropolitan) setup has several speeds/CVT, high compression engine, and fuel injection.

which = what? 130 mpg?
I have a 49cc Yamaha scooter. It had a CVT and a carburetor, and top on it 43 on GPS. It will go to about 46 with a slight down hill, but its screaming at that point so i don't do it.

It gets 90 mpg when run hard, but if I keep it around 25 mph, it gets just over 100 mpg.

Top speed, on flat level ground, according to my Bell Dashboard 100, is 31.8! I cruise easy at 25. Some days the bike runs better than others, but my lowest break- over speed, loaded, is 18mph.
