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 electrical shorts.

Use the appropriate tools to remove the seat and fuel tank. This will give you access to the engine and the spark plug.

Reattach the spark plug cap, ensuring it is securely in place. Reinstall the fuel tank and seat, making sure all connections are tight and secure.
