I am not really believeing this but, hey I'm throwing it out there...I ran 199.7 miles down to Ocala national forest and back on Saturday. Got on it twice bouncing off 8500. No big deal, easy riding, 45 to 65mph generally. Full tank when I left, it just took 3.97 gallons to fill it back up tight. Must be some mistake. I'm tring it again-checking milage that is. 40 mpg would be pushing it, but 50 mpg?, No way. (Bike has 500+ miles on it now.)My first tank on mine and I got 45.45 miles per gallon
