Ensure the bike is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by gently pulling it off the spark plug.

2. Remove the Old Spark Plug

Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free from the engine.

3. Inspect the Old Spark Plug

Check the old spark plug for signs of wear or damage. This can provide insights into the engine's condition. If the plug is oily or has excessive carbon build-up, it may indicate other issues.

Apply a small amount of anti-seize compound to the threads of the new spark plug if desired. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten it to the manufacturer's specifications.
