If I correctly read your message, you stated that you drove 100 miles and ended up with 1/4 of tank. My 2003 Harley Sportster gives me 125 miles to the tank. It has a peanut tank with 2.3 gallons. I just bought the Vulcan today. Does that mean that I will be getting the same miles for 5 gallons? IF that is the case, I was ripped off!!! Is that possible?????
