Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • Torque wrench
  • New spark plug (NGK BR10EG recommended)
  • Anti-seize compound

Step-by-Step Guide

1. Prepare Your Bike

Ensure your KX85 is on a stable stand 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

Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free. Inspect the old plug for any signs of damage or unusual wear, which could indicate engine issues.

3. Install the New Spark Plug

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

4. Tighten the Spark Plug

Once hand-tight, use the torque wrench to tighten the spark plug to the manufacturer's specification. For the KX85, this is typically around 18 ft-lbs. Do not overtighten, as this can damage the threads.

5. 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.
