Preparing Your ATV

Now that you have your supplies, it’s time to prepare your ATV for the spark plug change.

1. Park the ATV on a level surface: Make sure the ATV is stable and secure before you start working on it.

3. Remove the ignition key: Turn off the ignition and remove the key to prevent any accidental starting.
4. Remove the spark plug wire: Locate the spark plug wire connected to the spark plug and carefully pull it off.

Accessing the Spark Plug

The spark plug is typically located in the center of the cylinder head, near the top of the engine. To access it, you’ll need to:

1. Remove the air filter: This will give you better access to the spark plug.
2. Locate the spark plug: The spark plug will be a metal cylinder with a wire connected to it.
3. Remove the spark plug boot: Carefully pull off the spark plug boot, which is the rubber or plastic cover that protects the spark plug wire.

Removing the Old Spark Plug

Now that you have access to the spark plug, you can remove it using the following steps:

1. Position the spark plug socket: Place the spark plug socket over the spark plug, ensuring it is securely attached.
2. Use the ratchet wrench: Attach the ratchet wrench to the spark plug socket and slowly loosen the spark plug by turning it counterclockwise.
3. Remove the spark plug: Once the spark plug is loosened, you can remove it by hand.

Installing the New Spark Plug

With the old spark plug removed, you can now install the new one.

1. Inspect the new spark plug: Ensure the new spark plug is free of any dirt or debris.
2. Thread the new spark plug: Carefully thread the new spark plug into the cylinder head, making sure it is seated correctly.
3. Tighten the spark plug: Use the ratchet wrench and spark plug socket to tighten the new spark plug to the recommended torque. Do not overtighten the spark plug as this can damage the threads.
4. Reconnect the spark plug wire: Carefully reconnect the spark plug wire to the new spark plug.
5. Reinstall the spark plug boot: Replace the spark plug boot over the spark plug wire.
6. Reinstall the air filter: Put the air filter back in its place.
