Two things that might cheer you up: 1) The gas mileage improves as the engine breaks in. I've got about 4K on my bike now and I didn't hit reserve until 140. 2) You burn gas at a MUCH greater rate when traveling on the highway. On surface streets/trails you'll get closer to 55-60 mpg.
Good to know. That may explain alot. I've been mostly using my bike to commute to work, mostly highway riding. Kinda makes sense, as I keep the bike in the 5K-6K RPM range on the highway. My one real gripe w/ the bike is that 6th gear is spaced so close to 5th. I wish 6th had more of an "overdrive" spacing, so that you don't have to be doing nearly 6K RPMs at 80mph. I've been considering going down a couple teeth on the rear sprocket because of this.
