You know speaking of aerodynamics , the Myth Busters actually created a coating for a car that had the form of golf ball shaped holes on it , sure the paint made the car really heavy so they started messuring the MPG once the car averaged a certain speed since weight at certain speed does not affect MPG if maintained .
The golf ball shaped car actually gained a substantial MPG increase over the stock car.
I wounder if doing something similar to a bike would increase top speed and MPG .
Update, at about 1800 miles now, I am still averaging 50s mpg regularly with an occasional 40s mpg when I am having fun with it. Just removed the snorkel and gonna find out how it starts tomorrow morning at 40*F. No shims ad completely stock.
Also, putting a little more air pressure in the tires will increase the gas mileage (and lower the cornering ability). Do not go over the maximum pressure listed on the tire sidewalls, and this would be dangerous for track days and other fast riding.
A small light body shaped like a teardrop (narrow at the back) gets the highest gas or diesel mileage:
