    Bike stops running during warm-up idle?

    Any suggestions?

    My first thought is to check the air filter, then fuel filter, maybe idle adjust. I'm curious if any of you have come across the issue before, and what you did to fix it.

    A little more info might help like what year bike and if any mods. Do you hear fuel pump prime when you flip kill switch on? Plugs fouled? Could be a number of things

    Fouled spark plugs. Let them dry overnight and start again. If it does not help replace the plugs.

    When I fouled my plugs I had similar issue. I just waited a few hours and after that they work like nothing happened.

    ^^^^^^^^^^^Easier to replace so you know they are good plus they are cheap enough. But you do as you wish.

    I use a spark plug cleaner, then they look new again and they are dry. Dont have to wait overnight to dry. I am just saying.

    What year is the bike? If it's '08-up the DDFI-3 ECM has a spark plug cleaning feature. I learned that from Lunatic
    '08-up also have electronically adjusted idle.

    Post a video of a cold start. My no-info-given-to-diagnose-the-problem-answer is...... probably low idle and its stalling...
