    Cold low speed pop back

    My 2007 road king with efi pops back thru the intake when I first start riding at low speed. After it warms up it runs fine. It's been maintained to HD specs. Any help would be appreciated.

    Lean pop
    Most likely intake gaskets, very common when it gets cold, soon as it warms up they expand and seal

    Good luck

    Other thing it may be is just running a bit lean due to cold weather. If you never had the ECU mapped that may do it. If a carb them most likley gaskets

    one of the things that is often left out of a ride is the start up. letting the bike idle for a bit before taking off not only allows the ecu to catch up, but also allows the engine components come to temp. we let ours go for at least 5 minutes (rocker covers too hot to keep your hand on). just a thought....
