Have you checked your float levels? My guess is that it is leaking gas out of the vent tubes while you are riding. This happened to me quite a few years back.

I dont mean to sound like a smartass... but did you check your math? Remember, there's nothing more deceptive than the obvious.

I have 05 WR450F and get about 31 Miles of hard desert and hill climb miles from Cal City to Randsburg on a gallon or so. I am 230lbs. Something must be wrong with yours.
