Tools and Materials Needed

  • Torque wrench
  • Anti-seize compound

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 by pulling it off the plug cap.

2. Remove the Old Spark Plug

Use the spark plug socket wrench and ratchet 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 any signs of wear or damage. This can provide insights into the engine's condition. A worn or fouled plug may indicate issues with the fuel mixture or engine timing.

4. 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. Carefully thread the new spark plug into the engine by hand to avoid cross-threading.

5. Tighten the Spark Plug

Use the torque wrench to tighten the spark plug to the manufacturer's specifications. For the CR80, this is typically around 18 ft-lbs. Do not overtighten, as this can damage the engine.

6. Reattach the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until it clicks into place.
