Why does my gas mileage stink so far?

I have put about 200 miles on my new Buell XB12S so far (still breaking-in). Every independent review I read about this bike (about 10 different ones) say it should get about 40-43 mpg; so far after 2 fuel-ups I am only getting about 28-30mpg. I called the dealer where I bought the bike and he basically said if it's not leaking gas onto the ground nothing is wrong and that it could be because I am still breaking in the bike.

Other than riding the bike real hard, or a bad O2 censor can anyone think what could cause a motorcycle to get bad gas mileage? The bike is fuel injected and the check engine light is not on... meaning that when I turn the bike on there are not errors in the diagnostics...

Thank you!

1500 fifteen hunert miles. what you should be thinkin, is how does this machine work and how hard can you can work it. gas mileage should come later when the machine is ready for a good strokin.

I'd argue against that. 28-30 is bad even with it breaking in. With my Cityx I was still getting around 55-60 on a run even during that period. O2 sensors can play a part in economy to note. I'm not sure about the US but the UK dealers by in large don't have much of a clue when it comes to Buell's, find a specialist who can give you more of an informative answer.

as long as you keep it under 4,000rpms most of the time it should do over 40, mine did 44MPG at last fillup and I am still breaking in also, only got like 130 miles on it.

chuck, this might sound like a dumb question, but are you factoring in the bikes reserve? although its not a good idea to chance it, i've gone up to 31 miles with the fuel light on.Every time I fill up, I reset the trip meter. Reguardless of how hard I ride, I usualy get about 121 miles before the light comes on.Take that and the 31 miles i've gotten with the reserve, that comes out to about 43 miles per gallon.
the problems I have with my xb9r, is that I constantly smell gas, and every so often, the bike will just quit.I've had all the regular services and maintenance done by the dealer, they say its normal.

Silly question but have you checked your tire pressure? Also I have owned an xb since the very begining the 6th one off the line and have logged nearly 80k miles on two of them (60k/20k) and have only broken the mythical 50mpg a few times riding like a granny. However my throttle hand is more like a light switch on or off and very rarely go below 40 mpg if you allow for rounding up ie: 39.87. The bikes have been run stock and with buell race kits :muffler ecm high flow very little difference in mileage. Also how big are you? I am 6'7" and 265 so my milage suffers from a greatly increased cd.

Just picked up a cityx from an auction and now that I got some footpegs on it finally got to ride it around a bit. Love the bike compared to my Blast, but wasn't quite as strong as I'd thought it'd be. Then I noticed the check engine light is on. Well I'm used to working on cars and know what to check there, but wasn't sure where to start with the Buell. This is my first FI bike too, so it's time for some learning. Any ideas out there?

thanx and Namastae!

You cant factor in the reserve tank. You fill the bike up and run between 50 and 100 miles and refill. Divide your mileage by how much gas you could fit in.

I am buying a 07 12ss and now am confused the ads. said 65 mpg on the highway,is this false info. my 1200 roadster gets 53mpg I thought because of gearing,and weight the Buell would do better.

Trying to contact Andy (Mansfield UK),
I've just seen your comment on here and thought you might be a good contact considering how close you are to me geographically. I'm thinking of adding a Buell XB12cg to my garage (need a mate for my Monster) and from your comment about UK dealers not having much of a clue about Buells wondered which dealer you'd recommend. I was planning on having a ride over to Chesterfield at the weekend to have a look.
My email is [email protected]
Hope to hear from you soon,
Thanks, Catherine
