Dude, this is the 3rd thread you've started. Have patience and someone will be along shortly to help you out. My first thought is bad fuel or EITMS is active.

EITMS if turned on will kick in on your bike if ambient temp is over 80° when you come to idle and stopped. On initial start up if ambient temp is over 80° after 4 minutes of idle. If engine temp is over 180° ? (Not sure if I have that engine temp correct) when you come to a stop. These are the three ways EITMS will activate when turned on. In the mean time check codes.........bike off, don’t start, press and hold trip button while turning ignition to on, continue hold trip until diag shows up on odometer, then scroll trough systems by pressing trip button. All should end with N if you have a Y (yes) press and hold a short time until it gives you the code.

Checked the front spark plug wire in the gas tank area? Some have had rub through areas on that wire from rubbing against the tank.

If the EITMS is enabled it will only idle on the front cylinder at temps over 80F so you might want to check that also.
