    Yeah,

    change your jetting!!

    You will probably want to go with a JD jetting kit but you will want to go a little larger on the main. I would think with a big bore AND a Hotcam you will need Probably a 165.

    #42 Pilot jet.

    Try PM'ing Christi20. She did this a little while back and has redone her jetting. See what worked for her.
