1. Prepare Your ATV
Ensure your ATV is on a flat surface and the engine is cool to prevent burns. Disconnect the battery to avoid any electrical issues during the process.

The spark plug on the 2000 Honda TRX400EX is located on the right side of the engine. Remove the spark plug cap by gently pulling it off.

Before installing the new spark plug, apply a small amount of dielectric grease to the threads to ensure a good seal and prevent corrosion.
