Step 1: Access the Spark Plug

Begin by ensuring your ATV is on a flat surface and the engine is cool. Remove the seat and any necessary panels to access the engine compartment. Locate the spark plug wire and gently pull it off the spark plug.

Using a spark plug socket and ratchet wrench, carefully unscrew the old spark plug. Be cautious not to damage the surrounding components. Once removed, inspect the old spark plug for any signs of wear or damage, which can indicate engine issues.

Step 3: Install the New Spark Plug

Before installing the new spark plug, apply a small amount of dielectric grease to the inside of the spark plug boot. This helps prevent moisture and ensures a good connection. Hand-tighten the new spark plug into the engine, then use a torque wrench to tighten it to the manufacturer's specifications.
