    How long should you idle your Harley?

    Does the idle time differ for either a carbureted or fuel-injected bike? I have heard that fuel-injected bikes require less time to be started, then ridden. I am always afraid of letting a bike run for long because I have heard of engines getting damaged in this way. How true is this?

    I let my idle just long enough that my neighbors don't have a chance to call and complain. Seriously I read that it's important to let a Harley with a EVO run a few minutes to warm up before riding, the exact amount would be different according to the ambient temperature. Cold weather longer then hot or warm.
    Never ride faster then your angel can fly.

    I usually let my bike idle for about two minutes then I'm off. I also read somewhere that a Harley factory technical expert said that there was no scientific reason for long idle times before riding.

    I totally get what you're saying. I have neighbors that are pretty understanding, but even then I don't want to push my luck by trying their patience too long in the mornings.

    There is no need to idle your bike for extended periods of time. Just a couple of minutes is enough to do the trick. I know some people believe it should be longer, but there's no real benefit to idling it longer than two minutes.

    Just play it by ear and keep the temperature in mind. You're obviously going to want a longer idle time when it's 10 degrees outside than if it's 100.

    You never want to try their patience every morning. I idle mine for just a few minutes and then I am off. I never heard anything (before) about idling for a long time damaging the bike's engine.

    Air cooled.....not too long, liquid cooled, not too long but can get away with a bit longer. There is no point too let them get hot in the garage, on a warm day 30 seconds will do , you do t want too overheat it right off the bat.

    I just added an fp3 and now I monitor my engine temp. It takes longer than I woulda thought to get up to 200 degrees. But as long as you let the oil pressure get up and don't dog it, you're probably ok.
