Well, not as good as most, but better than some.
01 EG Classic with around 63K miles. riding varies, from puttering around town for half a tank then back and forth to work on the interstate running 75-80mph. Lowest was 35.5 and best has been 39.5 mpg. All stock, no mods, TC88.
I believe that keeping my rpm's in 5th gear around 2900 (about 65mph) i get the best mileage.
