Odometer Error?

Any one else not seeing these kinds of numbers? Seems everyone here is getting 6-8mpg more than I am. My bike is low miles and runs great otherwise. Any suggestions where to look? If I could get 150+ miles on a tank, it would make life a lot easier. Been looking at other bikes recently, ONLY because of the range I get on a tank. Sick of having to search for a place to fill up twice on every ride.
 
Sounds about right, remember it's an 800 lb bike
