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 cap by gently pulling it off the spark plug.

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