Kzoo, I have an 04 Heritage FI Stage 1, on the road I get 45 mpg and my low fuel light comes on at 130 miles like clockwork, and if I get gas right then it will only take 3 gal. Now supposedly I have a 5 gal tank but just looking at it it sure don't look like it's the same size as a 5 gal gas can. Just for my own piece of mind whenever my low fuel light comes I know I need to stop and get gas reasonably soon but it's not an emergency. I have run up to 160 170 miles with no problems, I reset my trip meter at every fillup and rely more on it than my fuel gauge. One thing I've allways wondered is it a 5 gal tank before or after they cram the fuel pump and filter in there. I'm not one for pushin so I choose to maybe get gas a little sooner than I actually have to. With no reserve on a FI bike you're pretty much done once it chugs.
