Step-by-Step Guide

1. Prepare Your ATV

Ensure your Bear Tracker is on a flat surface and the engine is cool to prevent burns. Disconnect the battery to avoid any electrical issues during the process.

2. Locate the Spark Plug

The spark plug is located on the engine's top side. Remove any covers or components that may obstruct access to the spark plug.

3. 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.

4. Check the Spark Plug Gap

Before installing the new spark plug, use a gap tool to ensure the gap is set to the manufacturer's specifications. This is crucial for proper engine performance.

5. Install the New Spark Plug

Apply a small amount of anti-seize compound to the threads of the new spark plug if desired. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the spark plug socket and ratchet to tighten it securely, but do not over-tighten.

6. Reassemble and Test

Reattach any covers or components removed earlier. Reconnect the battery and start the engine to ensure the new spark plug is functioning correctly.
