Anybody try to stretch out the mileage in a tank yet? I was filling up at around 100mi (when the gauge was showing I was low), but I always had about 1.5 Gal. left. I started going to about 110-120mi recently and it still seems like I could get some more out of it - if the rated capacity is right. I'm looking at some long rides and trying to plan fuel stops, what's the most anyones gotten out of a tank without running out of gas?
