big bore and mpg??
For those of you that have installed big bore kits in your bikes, how have they affected your mpg? Same, better, or worse? And of course I'm referring to after you quit wicking the throttle all the time, playing with the new extra power.....

From my perspective, comparing my 07 UC 96" w/Stage 1, Tune & Rinehart pipes vs. my 09 UC 103" Stage III, Tune & BUB 7 TD's, the average fuel mileage 'to date' is 1.8 mpg lower, and that I attribute to some bad fuel over a course of 5 weeks (was going to some stations that I 'thought' had good fuel based on past experience).
The overall average for my 09 UC is currently: 44.56 mpg. I have had a high mpg of: 56.58 and a low mpg of: 34.22
I generally always have my tour-pak full and the saddlebags at 50% full, riding solo for 70% of the time.

Why wouldn't I be? Just because I'm considering a little more power doesn't mean I want my fuel mileage to go to ****.

120", 125hp and 145tq, and have seen 50+mpg but regularly get 45. It is possible.

Well those certainly are impressive numbers but I still don't get the logic. I built my old muscle cars to have power. Why? To use that new power. Mpg was never a factor in my decisions when I wanted to build bigger. Going faster was. To each their own I guess.

Your old muscle car was probably carburated. With todays efi, a proper tune, you can have the best of both worlds. With my 107 I've ridden with stock bikes, gotten better milage and made them a lot smaller in my mirrors at will.
