To adjust the idle speed on a 2010 Honda Fury, you'll typically need to locate the idle adjustment screw. Here's a general guide:

1. Locate the Idle Adjustment Screw: It's usually located near the carburetor or throttle body. On the Honda Fury, it might be located on the side of the throttle body. It's typically a small screw with a knob or a slot for a screwdriver.
2. Warm Up the Engine: Start the motorcycle and let it warm up to normal operating temperature. This ensures that the idle speed adjustment is accurate.
3. Identify the Current Idle Speed: Use a tachometer to measure the current idle speed. The ideal idle speed for the Honda Fury should be specified in the owner's manual. Typically, it's around 1100-1200 RPM (revolutions per minute).
4. Adjust the Idle Screw: Turn the idle adjustment screw clockwise to increase the idle speed and counterclockwise to decrease it. Make small adjustments, usually a quarter or half turn at a time.
5. Monitor the Tachometer: While making adjustments, keep an eye on the tachometer to ensure that the idle speed is within the recommended range.
6. Test Ride: After making adjustments, take the motorcycle for a short test ride to ensure that the idle speed is stable and that the engine responds well to throttle inputs.
7. Fine-Tune if Necessary: If the idle speed is still not within the recommended range or if the engine response is not satisfactory, make further adjustments as needed.
8. Secure the Adjustment: Once you're satisfied with the idle speed, tighten any locking nuts or screws that secure the idle adjustment screw to prevent it from changing unintentionally.
9. Always refer to the specific instructions provided in the owner's manual for your Honda Fury, as the location of the idle adjustment screw and the recommended idle speed may vary slightly depending on the model year and any aftermarket modifications that have been made to the motorcycle

Its not an idle screw adjustment issue, it is a mixture screw adjustment issue, unfortunatly there is a special tool to adjust the mixture screws, pt no. 530035560 ( available from Hysqvarna dealers ) once you have this tool you can make an adjustment to the L screw on the carb, undo ( anti clock wise ) this screw ten minutes on a clock face ,this will richen the muxture, and should make it more stable on idle.

the idle isn't adjustable. you might want to have the idle air control motor checked out. they are prone to sticking in the open position allowing more air into the intake
