Tools and Materials Needed

  • Spark plug socket wrench
  • Ratchet
  • New spark plug (NGK BR9ES recommended)

  • Anti-seize compound (optional)

Step-by-Step Guide

1. Prepare Your Bike

Ensure your KX80 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

Using the spark plug socket wrench and ratchet, carefully unscrew the old spark plug from the engine. Be cautious not to damage the threads in the cylinder head.

3. Check the Spark Plug Gap

Before installing the new spark plug, use a gap tool to check the gap. The recommended gap for the KX80 is 0.028 inches. Adjust if necessary.

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 cylinder head by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up – do not over-tighten.

5. Reattach the Spark Plug Wire

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