I would call Jeff at Simons CPR. He will probably help you out.

Is your carb vent line plugged into the airbox with the airbox still factory configured?
Yes air box is stock I'm workin on it now I tried leanin the screws I tried a few positions rite now I'm at 2.25 idels fine but 4 to 6000rpms its gurgiln then it cleans up... plugs are wet at idel but it seems like if I lean it out the gurgle gets worse... should I fatin up a bit... simons specs are 2.50 turns seems like alot
