funny enough...
I was thinking about posting the same thing last night, just had my 12k service a few weeks back, and treated the bike to a powercommander III (second hand from a fellow tosser), stock exhaust etc.. I saw 62mpg, but went down to 56.6mpg over 55 miles. Was sorely tempted to pull over for petrol to see how close this was (as I always reset mpg/mileage counter after filling up). Couldn't be arsed in the end.
I have no reason to not believe this figure, as it now seems to sip fuel, even with my style of riding (could be described a enthusiastic).
Btw, the Powercommander is a nice bit of kit, fitted in minutes and does make a difference. Not majorly faster, but much much smoother fuelling (especially around the 5k rpm black-hole), which is all I can ask for, but looking forward to upgrading the header pipes later this year.
Cheers - dan
