Finally getting on the bike this year, and notice I have less power in 2nd from idle. If I recall last year, I could go from a stop in 2nd and have power at all spots on the throttle. This year, when in 2nd and at a stop, I crack the throttle and it bogs a little before it gets going. Any ideas? Never touched the jetting, only difference is regular gas, not "advance" premium I usually use, but doubt that would do it.
