Ensure your CR500 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it straight off the 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 completely removed. Inspect the old plug for any signs of damage or unusual wear, which could 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. Once hand-tight, use the torque wrench to tighten the spark plug to the manufacturer's specified torque setting.

4. Reconnect the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until you feel it click into place. Ensure it is securely attached to prevent misfiring.
