Mine seems to have coated the rear brake disk with carbon. Other than that, it's been running mint. I get about 40 MPG so far. Did the 2006, and 2007 carbon up the brake disks? | ||

It is not happening on my '07. If anything the thing runs too lean. If I had to err on one side or the other I'd rather it be lean, but ideally of course a perfect median would be uh, perfect. (And while I know there are adjustments I could make, I am too lazy/busy to do anything about it. Except whine and moan.) | ||

My '06 runs pretty clean out the pipe. | ||

It's been speculated that Buell fattened up the fuel map on the '08's so they'd run a bit cooler and surge less on the bottom end. That 15%-20% more fuel is going somewhere. I'm hoping the ECMSpy guru's will come up with an alternative fuel map that will trade off a little less fuel usage for a little more heat. (Message edited by rwven on June 06, 2008) | ||

All of the fuel map problems which I corrected, in order to get the bike to run right, were due to a 'too lean' condition, within the various cells. Given a choice (and within reason, of course) I would much rather have my bike run slightly rich, as it does now. For any number of reasons, stated previously. I never purchased the Uly for any MPG advantage ... I got 36-38MPG the last time I ck'd ( damn, I like those jackrabbit starts) and could care less as long as it runs well. Just my 2 cents. . | ||

Johnboy777, So you turned your '07ish Uly into an '08ish one! I'm not terribly disappointed with my XB12XT's 42 mpg, and he/she/it does run good. If a little tweaking will get me 45-47 with little downside? I'll take it..... | ||

Hey, Rwven With all due respect - forget about your MPG. Ride it, enjoy it, and have fun. These really are great bikes. John . | ||

John, Believe me, I have been! "Funnest" motorcycle I have ever ridden. The only time I would really like the extra mileage is when I am racking up the miles on a road trip. Great bikes? You sir are a master at understatement.  Ron. | ||

I'm not really complaining. Mine runs so smooth at low RPMs, it's hard to compare to my X1. I could use a bit more midrange grunt though. I'm keeping an eye out for a cheap XB12 muffler to hack. If it's running a bit on the rich side, it should run like a raped ape with a louder pipe, eh? |
