Tools and Materials Needed

  • Spark plug socket wrench
  • New spark plug (NGK CR6HSA recommended)
  • Socket wrench extension
  • Torque wrench
  • Anti-seize compound (optional)

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 straight off the plug.

2. Remove the Old Spark Plug

Using the spark plug socket wrench and extension, carefully unscrew the old spark plug from the engine. Turn counterclockwise until it is free.

3. Inspect the Old Spark Plug

Check the old spark plug for any signs of wear or damage. This can provide insight into the engine's condition. A worn or fouled plug may indicate other issues.

4. Install the New Spark Plug

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 the plug to the manufacturer's specifications (typically around 9 ft-lbs for the XR80).

5. Reconnect the Spark Plug Wire

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