Step-by-Step Guide

Step 1: Preparation

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.

Step 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 loose enough to remove by hand. Inspect the old spark plug for any signs of wear or damage, which can indicate engine issues.

Step 3: Install the New Spark Plug

Apply a small amount of anti-seize compound to the threads of the new spark plug. This will help prevent it from seizing in the cylinder head. Carefully thread the new spark plug into the cylinder by hand to avoid cross-threading.

Step 4: Tighten the Spark Plug

Once the spark plug is hand-tight, use the torque wrench to tighten it to the manufacturer's specified torque setting. This ensures a proper seal and prevents damage to the cylinder head.
