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 cap by gently pulling it off the spark plug.

2. Remove the Old Spark Plug

Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is completely removed. Inspect the old plug for any signs of wear or damage, which can indicate engine issues.

3. Install the New Spark Plug

Before installing the new spark plug, apply a small amount of dielectric grease to the threads. This helps prevent corrosion and ensures a good connection. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten it to the manufacturer's specifications, typically around 8.7 lb-ft (12 Nm).

4. Reattach the Spark Plug Cap

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