How to Adjust the Idle on a Honda 50R Bike

by Chris Gilliland

Honda's mini dirt bikes, such as the XR50R, have been used by young motocross riders for years. Featuring an easy-to-use automatic transmission to help youngsters learn how to control their motorcycle, the XR50R is as simple to maintain as it is to ride. Adjusting the engine's idle speed is one of the many small maintenance items that can be taken care of by the XR50R's owner.

Step 1

Start the motor and let it run for between 2 and 5 minutes to allow the motor to warm to its operating temperature.

Step 2

Locate the Phillips idle adjustment screw on the right side of the carburetor.

Step 3

Turn the idle adjustment screw clockwise with a Phillips screwdriver to increase the engine's idle speed. Turn the screw counterclockwise to lower the idle speed.

Adjust the engine idle speed so that the motor is running smoothly without chugging or racing. Stop the motor.

Tip

  • If you do not feel comfortable performing this task, have the idle adjusted by a Honda technician.

Warning

  • Avoid making idle speed adjustments to a cold motor. A cold motor will not run properly and will require you to reset the idle speed once it is warmed.

Items you will need

  • Phillips screwdriver
