LTZ400 Backfires with choke off.

04 LTZ400 (totaly stock) After cleaning my carb my bike idles and revs awesome with the choke on, as soon as I turn the choke off it will backfire while reving and die if I let it idle. Any ideas?

This or potentially you put the clip a notch or more to high on the needle. Or you need to adjust the air/fuel screw. In any case, the quad is now running lean on the pilot circuit
