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 to prevent accidental starting.

2. Remove the Old Spark Plug

Use the spark plug socket and ratchet wrench to carefully remove the old spark plug. Turn counterclockwise until it is free. Inspect the old plug for any signs of damage or wear, 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.

Use the torque wrench to tighten the spark plug to the manufacturer's specifications. For the 2002 Kawasaki KX250, the recommended torque is 18 ft-lbs. Do not overtighten, as this can damage the threads.
