    Greatings one & all-
    A coworker referred me to this forum to assist with an issue I'm having. I have an 07 FLSTF (Fatboy), owned since new. After about 2 years and less than 10K, it began intermittently stalling when the engine was running hot and moderate RPMs. Often when the stall is predicated by the high idle kicking in and causing the engine to scream at idle. If the motor does stall or I shut it off, the subsequent start will be very rough with back fires and strong fuel odor.

    The dealer said it was a loose ground wire and replaced it, then tried a crank sensor. No changes. The other 98% of the time the bike runs great.

    Hope to hear from you all with some ideas, thanks in advance.

    Welcome from So. Texas. Has it been checked for any codes? Have you checked it for any Intake leaks? I would assume it is Fuel Injected. Has there been any Mods to the bike,pipes, fueler, cams, etc?

    I would think that the dealer checked for codes. Do you know if any were found? have you tried cleaning the IAC?

    Well, only a few months later, but I have another lead to run down. I did look at the IAC and read the other link, no joy. I'm about to take it into a local dealer and work this out, but before I do, I read on line again, and came across an HD service bulletin, but I can't read it in full. Does anyone have full access to SB-M-1220? Thanks

    Welcome to the forums from Fort Bragg, NC. Off-subject, that flagpole in the background looks familiar. Is that Pope AAF?
