So I started trying to tune one of my shees today, since it was warm out, this is my first time doing it. The bike is stock internally, and has t5s, pods, +4 timing, 310 jets, and the long dynojet needles on the 4th clip. I got the idle set good, and the carbs are synced with my sync tool. Air screws are 1.5 out. When driving, the bike is ok right off idle, but bogs if you give it a lot of gas, then takes off. If you rev it up high, it also seems to be backfiring slightly. This seems like it is too rich correct? Now do I need to adjust the needles or the air screws?
