MISCELLANEOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP:
With the K&N on and stock jet settings, it was so lean I could not go past maybe 1/4 throttle without it stuttering and hesitating (and not picking up any more speed). It was like riding a moped, and I could not get above about 50mph. I had changed the jets to the 112s anticipating needing them with the custom exhaust, but will probably be keeping the stock exhaust at least for a while and have ordered smaller jets. I hadn't tried the 110s with the stock exhaust.
After playing with the mixture screws, I settled around 3.5 turns out (roughly), and now it starts up much better than before and will cleanly pull from under 2k RPM. The low-end response has picked up enough that even with my 16/41 gearing (25% taller than stock), I will occasionally just leave it in 2nd (same ratio as stock 3rd gear) if I am doing a lot of stopping and going, and it will move just fine for regular traffic / neighborhood streets.
