Steps to Change the Spark Plug
- Turn Off the Engine: Ensure the engine is completely off and cool to the touch to avoid burns or other injuries.

- Remove the Spark Plug Cap: Gently pull the spark plug cap off the plug. Be careful not to damage the cap or the wire.
- Unscrew the Old Spark Plug: Use the spark plug socket wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free.
- Check the New Spark Plug: Before installation, check the gap on the new spark plug using a gap tool. The correct gap for the YZ80 is typically around 0.024 inches. Adjust if necessary.
- Apply Anti-Seize Lubricant: Apply a small amount of anti-seize lubricant to the threads of the new spark plug to prevent it from seizing in the engine.
