Ok i am screwing around with jetting because I just rebuilt and added an exhaust. Right now im 310 mains, stock pilots, 1.5 turns out, needle clip in middle. Im near sea level (200 feet) and the temp is high 80s lower 90s. I cant seem to get it to run right. Whenever I am cruising in first at idle and hit the gas it bogs a little but then it will hit hard. Whenever i have it kept at about 1/2 throttle it kinda spits and sputters. Whenever i get on it past 1/2 throttle it hangs on to the rpms. I can let off and the rmps stay high. Its like the throttle is sticking I kill it, then I can start it right back up and it idles fine. Any clues on what I should adjust with my jetting. Also, is this throttle issue jetting or something else. THanks for any help I have been messing with this soooo much its not making much sense.
