OK, got it out on the county highway. Hit 60mph on flat into a light wind. Down to about 50-53 on hills. This, on the scooter's spedometer. Haven't checked it against the GPS. Filled up on way back and figured 48 mpg. Not too great.
I normally get 70-80 MPG. One thing I did notice is I can get more gas in the tank if on the centerstand. If you fill up on the side stand one time and centerstand the next ( or vice versa ) it will throw off your MPG calculations.
