My 2007 CVO 110" SE Ulltra with STAGE 1 EFI KIT, RACETUNER AND RINEHART'S SUCKS GAS. I know that the big engine, the rate of speed that I ride and the weight I usually carry with my wife and the dog all contribute to the mileage. I really stress taking my trip next week from Long Island to the Florida Keys wondering if I stray off of a major route will I get stranded. I don't want to spend the entire ride looking at my fuel guage. ANY SUGGESTIONS?
