Approx. how many miles do you get on your Fat Boy? I have a LED gas gage on mine, and it is so touchy, I fill up bike and go 20 miles and it has dropped down 2 or three lights, the solid red light comes on around 140 miles? And then I get gas and it only takes approx. two gallons! This is a headache. and also for some reason with having this LED gage, my light on my dash to show low fuel does not come on? Should I switch this back to a standard gas gage?
