I see in lots of threads folks saying they get 130, 140 even 150 miles from a tank of gas. The most I've ever gotten after having to switch to reserve is 117 (I was on fumes!), and mostly I have to go to reserve at 95 or 100 miles. I generally refill before 100 miles just to be safe, and I never assume that I'll get more than that. It doesn't seem to matter much whether it's highway or city miles, that's all I get. Could my odometer be wrong? I do know that when I ride with my buddy who has an old Silverwing the trip mileage on the two odometers is always different. His will read 10 or 15 miles further on a 100-120 mile trip. I am positive that my speedo is at least 10% high and maybe even more. Is it riding style? I don't think I over-accelerate too much. I do like to twist the throttle good now and then, but that's what it's for, right? Is it weight? I do weigh around 300. Maybe it's just you skinny guys getting good mileage. Could be all of the above I suppose. If so I can live with it. Just doesn't make sense that mileage should be so different from one virtually identical bike to another.
