After thinking on things since last night I may have jumped the gun on my estimate. I was a little pissed cause I ran out of gas about 100 yards from a gas station near my home. This bike does not feel heavy unless you have to push it. ;-)
Anyway, I thought I had plenty of fuel when I left work so I did not bother getting gas, thinking I'd stop off on my way a little closer to home. I have a dailey 100 mile commute. I thought it a little strange that the bike took only 5.54 gallons. The thing was empty as far as I could tell. There musta been a little bit sloshing around in there but I could not see or hear it.
I will run this entire tank through and see what I get. I have to admit that my earlier estimate included more city driving than usual. Since I put the Staintunes on I get "slightly" worse mileage in the city because I'm always gassing it from stoplights, just to hear the ehaust. ;-)
