Steps to Change the Spark Plug
- Ensure Safety: Make sure the engine is cool to the touch to prevent burns. Turn off the ignition and remove the key.
- Locate the Spark Plug: The spark plug is located on the right side of the engine. You may need to remove the seat or any obstructing panels for better access.
- Remove the Spark Plug Cap: Gently pull the spark plug cap off the spark plug. Be careful not to damage the wire.
- Remove the Old Spark Plug: Use the spark plug socket wrench to unscrew the old spark plug. Turn counterclockwise until it is free.
