Step-by-Step Guide

Step 1: Locate the Spark Plug

The spark plug on the 2011 Polaris Sportsman 90 is located on the right side of the engine. You may need to remove the plastic cover to access it. Ensure the ATV is turned off and cooled down before starting.

Step 2: Remove the Spark Plug Cap

Carefully pull the spark plug cap off the plug. Be gentle to avoid damaging the wire or the cap itself.

Step 3: Remove the Old Spark Plug

Using the spark plug socket and ratchet wrench, turn the spark plug counterclockwise to remove it. Inspect the old plug for any signs of wear or damage, which can indicate other engine issues.

Step 4: Prepare the New Spark Plug

Check the gap on the new spark plug using a gap tool. The correct gap for the 2011 Polaris Sportsman 90 should be set according to the manufacturer's specifications. Apply a small amount of anti-seize compound to the threads of the new plug if desired.

Step 5: Install the New Spark Plug

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 snug it up. Do not over-tighten, as this can damage the threads.

Step 6: Reattach the Spark Plug Cap

Push the spark plug cap back onto the new plug until it clicks into place. Ensure it is secure to prevent any misfires.
