I think I could answer this question myself but you guys are the experts. I ride in Jersey so the weather changes all the time. I went for a ride and it was about 90deg and humid. Shee ran like shit with 310 mains, spuddering and slugish getting to high RPM. So I put 300 mains in there but the next time I rode it was about 75deg and cool, but shee ran like a champ. I plan to ride until it gets below 30deg or so. So my question is, aprox how many degs = main jet change? Thanks guys.
