Step-by-Step Guide

Step 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 to prevent accidental starting.

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

Step 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.
