Step-by-Step Guide

1. Prepare the 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 carefully unscrew the old spark plug from the engine. Turn counterclockwise until it is completely removed.

3. Check the Spark Plug Gap

Before installing the new spark plug, use a gapping tool to ensure the gap is set to 0.024 inches (0.6 mm). This is crucial for proper ignition and engine performance.

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 torque wrench to tighten the spark plug to 7.2 ft-lbs (10 Nm).

5. Reconnect the Spark Plug Wire

Attach the spark plug wire back onto the new spark plug, ensuring it is securely connected.
