Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • New spark plug (NGK BR8ES recommended)
  • Torque wrench
  • Anti-seize compound

Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your KX125 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.

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 may indicate other engine issues. If the plug is oily or has excessive carbon buildup, it might 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. Carefully thread the new 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 18-22 ft-lbs for the KX125).

Step 5: Reattach the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until it clicks into place. Ensure it is secure to prevent misfires.
