    First sorry if i posted this in the wrong spot. I have an 09 classic and after warm up i will start the bike and it will idle at around 1800 rpm. after you get moving a bit it goes back to normal

    Bike has stage one and PC-v with auto tune.

    We had the same issue on my wife's '02 Fatboy.
    After cleaning the IAC and checking stuff out, I found that a vacuum line plug on the back of the throttle body was cracked and leaking.
    Replaced with a new one.
    Works great now!
