Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • New spark plug (NGK C7HSA recommended)
  • Torque wrench
  • Dielectric grease

Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike 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.

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, then remove it from the engine.

3. Inspect the Old Spark Plug

Check the old spark plug for signs of wear or damage. A worn-out spark plug can indicate other engine issues. If the plug is oily or has excessive carbon build-up, further inspection of the engine may be necessary.

4. Install the New Spark Plug

Apply a small amount of dielectric grease to the new spark plug's threads. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten the spark plug to the manufacturer's specifications (typically 8.7 lb-ft for the KLX140R).

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 securely attached to prevent misfires.
