Tools and Materials Needed

  • Ratchet wrench
  • Torque wrench
  • New spark plug (NGK BR9ES recommended)
  • Anti-seize compound

Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool to the touch. Disconnect the spark plug cap by pulling it straight off the plug.

Step 2: Remove the Old Spark Plug

Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free from the engine.

Step 3: Inspect the Old Spark Plug

Check the old spark plug for signs of wear or damage. A worn plug can indicate other engine issues. If the plug is oily or has excessive carbon buildup, it may be time to adjust your fuel mixture or check for oil leaks.

Step 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 and prevent thread damage. Carefully thread the new spark plug into the engine by hand to avoid cross-threading.

Step 5: Tighten the Spark Plug

Use the torque wrench to tighten the spark plug to the manufacturer's specifications. For the KX100, this is typically around 18 ft-lbs. Do not overtighten, as this can damage the threads.

Step 6: Reattach the Spark Plug Cap

Push the spark plug cap back onto the new spark plug until it clicks into place. Ensure it is secure to prevent misfires.
