Tools and Materials Needed

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

Step-by-Step Guide

1. Prepare Your Bike

Ensure your KX125 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.

2. Remove the Old Spark Plug

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

3. Inspect the Old Spark Plug

Examine the old spark plug for signs of wear or damage. A worn or fouled plug can indicate other issues with your bike, such as improper fuel mixture or engine problems.

4. Install the New Spark Plug

Apply a small amount of anti-seize compound to the threads of the new spark plug. This will help prevent the plug from seizing in the cylinder head. Carefully thread the new spark plug into the engine by hand to avoid cross-threading.

5. Tighten the Spark Plug

Using the torque wrench, tighten the spark plug to the manufacturer's specifications. For the KX125, this is typically around 18 ft-lbs. Do not overtighten, as this can damage the threads.

6. Reattach the Spark Plug Cap

Firmly push the spark plug cap back onto the new spark plug until it clicks into place. Ensure it is securely attached to prevent misfires.
