MPG before and after mods?

Hi, any stats on MPG before and after installing exhaust/intake/programmer? The only info i could find was this---------------"Even with Machtig’s lower gears and intake/exhaust/ECU-FI programming mods running absolutely flat out on a fully loaded and non-aerodynamic WR250R due to the saddle bags still allowed almost 40 mpg at its worst. At his best, was 70 mpg with the same bike and similar conditions but not WOT is all.

I suspect the modifications to the intake/exhaust and ECU added another possibly 20% increase in HP while lowering the FE of his WR250R (the on/off-road variant) maybe 10% from OEM if that helps?" Does this sound correct in your experiences-20%+HP with 10% reduction in MPG? I realize with a couple more ponies that the throttle will get twisted heavily at first and hence lower MPG...but with similar riding styles whats the MPG upshot of opening up the WRR? thanks

Full FMF exhaust and power programmer, airbox mod, saddle bags, and a big ass duffle on the back of my WR250x netted me as high as 60+mpg and as low as 45-50mpg between yesterday and today. Yesterday was bombing around sweet 1.5lane fresh twisty pavement, today was slogging through the rain and wind. Same mileage I got when it was an R. Same mileage it got when stock.

YMMV.

If there is any difference, its not much at all. Like maybe a change from 50 down to 48, or even less. The mods are easily worth more in smiles.

My bike is a '08 wrr, full fmf exhaust n programmer, all free mods, 'cept AIS, with a lil xtra airbox mod.
My buddy's bike is a '10 wrr , completely stock.
We ride together all the time, and our mileage is very close...My bike seems slightly thirstier by minor degrees...but I'm crankin it whenever I can, with limited skill...no regard, whatsoever, for mileage. I know/assume my buddy is similar...but I am probably more of an ass. Therefore, I assume I would burn slightly more fuel than him, on any given day...even/especialy if the bikes where set up identical.
So, I assume that narrows the difference even more...in my favour.
Wohooo...I get more power per buck than he.

thanks for the replies you guys-good to know with fuel prices these days opening up the bikes performance won't have to necessarily cost me a lot more to use it...now if i can just figure out how to buy the parts in Canada for a reasonable price....i like Mucker's response.."Wohooo...I get more power per buck than he."..... thats what it's all about these days

I wish I could track this, but since the gearing change I know my odometer lies...

I'm going with mucker on this, too. The mods don't have that much of an effect on mpg's.. riding habits & style have much more. I've got all the mods, but still ride like an old lady, so i get 60's on easy pavement, & seldom below 60 even off road. I've gotten low 70's on long easy stretches of 55 mph. I am geared higher than most, which also helps.

My worst mileage comes on interstate & 70mph rides.. Mpg's go down rapidly as you increase speed. Coming home from utah one time i was averaging 80+mph trying to stay ahead of a storm.. my mileage was in the 40's!

I believe gearing and your right hand have the biggest influence on mpg. I can still get well into the 70 and even 80s when I try to get good mpg, though getting 50 and 40s is pretty easy as also.

I have all the power type more but a stock header. 14 49 gearing. Never had the chance to ride it stock.
