Brute force fuel millage

[JDM]

I have a 07 750 and I was wandering what other people where getting on a tank of fuel. I have a muzzys exhaust system and a dyna jet stage 1, with a K&N. I also put on a set of mudlight xtrs that are 26x9/11x12. If I ride hard I can get 30-40 miles on a tank and I think the best I've got was 60 just riding roads. The only reson I ask is I ride with a guy that has a 04 artic cat 650 with the Kawi motor and he averages 60 miles on a tank. Should I be getting that much less on a tank?

[Which 450?]

my '06 got about 10mpg, consistantly. my '08 (efi) gets about 18 mpg. it has a 5.5 gallon tank, so you are probably about right. I figured this out in west virginia, filling up at the pump, hitting the trip reset, then filling back up later.
