Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • Torque wrench
  • New spark plug (check your owner's manual for the correct type)
  • Anti-seize compound

Step-by-Step Guide

1. Prepare Your Bike

Ensure your CR250 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. Inspect the old plug for any signs of wear or damage, which can 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 will make future removal easier and prevent thread damage. Carefully thread the new spark plug into the engine by hand to avoid cross-threading.

4. Tighten the Spark Plug

Use the torque wrench to tighten the spark plug to the manufacturer's specifications. Over-tightening can damage the threads, while under-tightening can lead to poor engine performance.

5. Reconnect the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until you feel it click into place. Ensure it is securely attached to prevent misfires.
