Step 1: Prepare Your Bike

Ensure your Cobra CM50 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it off the spark plug cap.

Use the spark plug socket wrench and ratchet to carefully unscrew the old spark plug from the engine. Turn counterclockwise until it is completely removed.

Firmly push the spark plug wire back onto the new spark plug until it clicks into place.
