Tools and Materials Needed

  • Spark plug socket wrench
  • Ratchet
  • New spark plug (NGK B9ES recommended)

  • Anti-seize lubricant

Steps to Change the Spark Plug

  1. Preparation: Ensure the engine is cool to prevent burns. Place the bike on a stable surface using a stand.
  2. Remove the Spark Plug Cap: Gently pull the spark plug cap off the plug. Be careful not to damage the wire.
  3. Remove the Old Spark Plug: Use the spark plug socket wrench and ratchet to unscrew the old spark plug. Turn counterclockwise until it is free.
  4. Check the Gap: Use a gapping tool to ensure the new spark plug is set to the correct gap, typically 0.028 inches for the KX80.
  5. Apply Anti-Seize: Lightly coat the threads of the new spark plug with anti-seize lubricant to prevent it from seizing in the cylinder head.
  6. Install the New Spark Plug: 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, but do not over-tighten.
  7. Reattach the Spark Plug Cap: Push the spark plug cap back onto the new plug until it clicks into place.
