Step-by-Step Guide

1. Prepare Your Bike

Ensure your Yamaha YZ80 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it off the plug cap.

2. Remove the Old Spark Plug

Using the spark plug socket wrench, carefully unscrew the old spark plug from the engine. Be cautious not to damage the threads in the cylinder head.

3. 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 ignition and performance.

4. Install the New Spark Plug

Apply a small amount of anti-seize lubricant to the threads of the new spark plug. Carefully thread the new 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.
