I originally filled the tank to the inner ring with the bike on the kickstand. My kickstand seems to have a little more tilt than most I've seen (don't know why). Anyway, I now sit on the bike and hold it upright and fill to the inner ring. I now consistantly get more than 20 additional miles before hitting reserve. I've also recently figured out that my odometer reads about 10% less miles than traveled. Add that in and I'm way better than originally thought.
