Step-by-Step Guide

1. Preparation

Ensure the engine is cool to prevent burns. Place the bike on a stable stand to keep it upright and secure.

2. Remove the Old Spark Plug

Locate the spark plug on the right side of the engine. Use the spark plug socket and ratchet wrench to carefully unscrew and remove the old spark plug. Inspect it for any signs of wear or damage, which can indicate engine issues.

3. Install the New Spark Plug

Apply a small amount of anti-seize compound to the threads of the new spark plug. This will make future removal easier and prevent thread damage. Carefully thread the new spark plug into the engine by hand to avoid cross-threading.

4. Tighten the Spark Plug

Use the torque wrench to tighten the spark plug to the manufacturer's specifications, typically around 18-22 ft-lbs. Avoid over-tightening, as this can damage the threads.
