I ony get about 25mpg too. I know its terrible gas milage,tried going lower needle settings and smaller piolots.Had to bump it back up(1st G,a "98")and could still go up in the pilots to 40s.I have a Holeshot header and high mount comp exhaust,150mains,38.5 piolots,clips@1.5 from the top.(I know I could drop the washer and go the full knotch,but I like to get at least 100 miles out of a tank)5deg. advacer, K&N pods and gsx-r 750 cams (just dropped them in,did'nt mess w/ the timing.)Now I'm 2nd guessing the piolot sizes. I have the stock piolot back in and could still go up another 1.5,but now I do'nt remember if its 38.5s 0r 40s. But either way my fuel milage still sucks.
Maybe there could be a wrist problem associated with this?
