Hi - I've seen a couple threads about this from the past, but I'm wondering if this is a common thing. My fuel indicator light comes on, with the displayed countdown of 30 miles to go. The 30 miles counts down considerably faster than a real 30 miles. The fuel gauge shows very close to empty. BUT, when I fill up, at maximum I need to put in 3.5 gallons. My FXDWG has a 4.7 gallon tank. Anyway, when I calculate mileage I am right around 40-42 mpg. So there seems to be a phantom gallon in there. I know I should cart a gallon on the back of my bike, and ride it out to see how far it will actually go, regardless of the gauge and indicator light, but really I'm just wondering how common this is, and whether it can be fixed so it reads correctly. Thanks for any insight!
