Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it off the spark plug cap.

2. Remove the Old Spark Plug

Use the spark plug socket wrench to loosen and remove the old spark plug. Turn counterclockwise until it is free. Inspect the old plug for any signs of damage or excessive wear, which could indicate other engine issues.

3. Check the New Spark Plug

Before installing, check the gap on the new spark plug using a gapping tool. The correct gap for the 2021 Yamaha PW50 is 0.024 inches. Adjust if necessary.

4. 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 socket wrench to snug it up. Do not over-tighten as this can damage the threads.

5. Reattach the Spark Plug Wire

Push the spark plug wire back onto the new spark plug until it clicks into place, ensuring a secure connection.
