Tools and Materials Needed

  • Spark plug socket wrench
  • Ratchet
  • New spark plug (NGK B9ES recommended)
  • Gapping tool
  • Anti-seize lubricant

Step-by-Step Guide

Step 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.

Step 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.

Step 3: Check the Spark Plug Gap

Before installing the new spark plug, use a gapping tool to ensure the gap is set to 0.7mm (0.028 inches). This is crucial for proper ignition and engine performance.

Step 4: Install the New Spark Plug

Apply a small amount of anti-seize lubricant to the threads of the new spark plug. Carefully thread the new plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up – do not over-tighten.

Step 5: Reattach the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until you feel it click into place.
