Alright, the first thing I did with this bike after I got it was go up to a 155 main jet since the prior owner put on pipes and a K&N, but did not touch the carb. I then put a metal, round-head screw in the two lines coming out of the PAIR valve to stop the popping. I went for my first ride yesterday and made 43.6MPG, which is WAY up from the prior 41~42MPG. I went on a long ride today and while I have not fueled up again yet, it appears to be even better. Is this the normal response from plugging the PAIR valve and putting in the right size main jet?
