1. Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool to the touch. Disconnect the battery to prevent any accidental starts.

The spark plug on the 2023 Honda CRF125FB is located on the right side of the engine. Remove any components obstructing access to the spark plug, such as the side panel or seat, if necessary.
