Step-by-Step Guide

1. Prepare Your Bike

Ensure your 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 and ratchet to carefully unscrew the old spark plug. Turn counterclockwise until it is loose enough to remove by hand.

3. Check the Spark Plug Gap

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

4. Install the New Spark Plug

Apply a small amount of anti-seize lubricant to the threads of the new spark plug. Carefully screw it into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up – do not over-tighten.

5. Reattach the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until you feel it click into place.
