The fuel injected Harley Davidson has an idle speed that is controlled by the computer. If you want to adjust the idle, you will need to do it through the computer. To do this, you will need to access the menu on the computer and find the idle adjustment setting.
Once you find this setting, you can change the idle speed up or down as needed.
- Park the Harley on level ground and turn off the engine
- Allow the motorcycle to cool for at least 30 minutes before beginning this process
- Raise the fuel tank by loosening the two screws that hold it in place, using a Phillips head screwdriver
- Be careful not to over-tighten these screws when you put the tank back on later
- Locate the idle mixture screws on either side of the carburetor throats
- These are usually labeled with an “I” or have a picture of a screw next to them
- Turn both idle mixture screws one full turn counterclockwise, using a flathead screwdriver, then start up the Harley and let it warm up until it reaches operating temperature, which is about 160 degrees Fahrenheit according to Haines Manuals Incorporated
- 5 Let the motorcycle idle for about five minutes so that you can get an accurate reading from the tachometer

How Do You Adjust the Idle Speed on a Fuel Injected Motorcycle?
If your motorcycle has a fuel injection system, you may need to adjust the idle speed from time to time. This is typically done when you first start up the motorcycle after it’s been sitting for a while, or if the engine has been running hot and needs to be cooled down.
To adjust the idle speed on a fuel injected motorcycle, start by warming up the engine.
Then, turn off the engine and locate the screws that adjust the idle speed. These are usually located near the throttle body or air intake. Turn these screws until you reach the desired idle speed.
Be careful not to over-adjust, as this can damage the engine.
How Do You Adjust the Idle on a Harley?
If you’re wondering how to adjust the idle on your Harley, there are a few things you’ll need to know first. The most important thing is what kind of Harley you have. There are two main types of Harleys- those with carburetors and those with fuel injection.
If you have a carbureted Harley, the process is different than if you have a fuel injected one.
Assuming you have a carbureted Harley, the first thing you’ll need to do is find the idle mixture screws. These are usually located on the back of the carburetor (if you’re not sure where they are, consult your owner’s manual).
Once you’ve found them, turn each screw in (clockwise) 1/8th of a turn at a time until the engine speed drops noticeably. At this point, back each screw out (counter clockwise) 1/4th of a turn.
Now it’s time to set your idle speed.
To do this, find the throttle stop screw and turn it in (clockwise) until the engine just starts to stall. Then back it out (counter clockwise) 1/8th – 1/4th of a turn so that the engine stays running without stalling but runs smoothly without any hunting or hesitating.
And that’s it!
Those are all the steps necessary for adjusting the idle on your Harley Davidson motorcycle!
How Do I Reset My Harley Idle?
If you’re wondering how to reset your Harley idle, there are a few things you’ll need to do. First, you’ll need to find the right spot on your bike to adjust the idle. Next, you’ll need to turn the knob or screw that controls the idle until it’s in the correct position.
Finally, you’ll need to restart your bike and let it idle for a bit so that the new setting can take effect.
What Rpm Should My Harley Idle At?
Assuming you are talking about a Harley Davidson motorcycle, the ideal idle rpm range is 950-1050rpm. This can vary slightly depending on the model of Harley Davidson motorcycle. You can find your ideal idle rpm by starting at 950rpm and slowly increasing the throttle until the engine runs smoothly.

Harley Davidson Fast Idle Problem
Harley Davidson is known for their quality motorcycles. However, some owners have complained about a fast idle problem with their bikes. This can be a serious issue because it can cause the engine to rev up and down erratically, making it difficult to control the motorcycle.
There are a few things that can cause this problem, so it’s important to troubleshoot and find the root of the issue before trying to fix it.
One possible cause of this problem is an air leak in the intake system. This can be caused by a number of things, such as a loose clamp or hose, or even a cracked manifold.
If you suspect an air leak, the best way to check is by using a carburetor pressure tester. This will help you identify any leaks in the system so that you can repair them.
Another potential cause of fast idle on Harley Davidson motorcycles is dirty carburetors.
Over time, dirt and grime can build up in the carburetors and affect how they work. This can lead to poor fuel mixture and uneven idling. To clean your bike’s carburetors, you’ll need to remove them and soak them in a solution designed specifically for cleaning carburetors.
Once they’re clean, be sure to reinstall them correctly and adjust the idle speed screw until the problem goes away.
Conclusion
If you have a Harley Davidson with fuel injection, you may need to adjust the idle at some point. This is not a difficult task, but it is one that requires precision. Here are the steps you need to follow to adjust the idle on your Harley Davidson:
1) Warm up the engine by riding for at least 15 minutes. This will ensure that all the parts are properly lubricated and at operating temperature.
2) Park the bike on level ground and turn off the engine.
Let it cool down for at least five minutes so that you can safely work on it.
3) Locate the throttle body screw near the air intake duct. It is usually labeled “idle.”
4) Turn the screw clockwise or counterclockwise until you hear the engine change speed. Continue turning until you reach the desired rpm range for idle, which is between 950 and 1050rpm.
