Try a #48 pilot jet and a #40 leak jet move your stock needle to the 5th clip from the top. If that does not do it then you have to start modifying your AC pump circuit. Your bike should wheelie and rip off of idle and not fall flat on its face. Also set your idle a little higher. You should be able to find a combination that works well.
