Step 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 gently pulling it off the spark plug.

Step 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 loose enough to remove by hand. Inspect the old spark plug for any signs of damage or wear, which can indicate engine issues.

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.
