Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire to prevent accidental starting.

Use the spark plug socket and ratchet wrench to carefully remove the old spark plug. Turn counterclockwise until it is free. Inspect the old plug for any signs of wear or damage, which can indicate engine issues.
