1. Prepare Your Bike
Ensure your bike is on a stable surface and the engine is cool to the touch. Disconnect the battery to prevent any accidental electrical shorts.
2. Remove the Seat and Fuel Tank
Use the appropriate tools to remove the seat and fuel tank. This will give you access to the engine and the spark plug area.

5. Install the New Spark Plug
Apply a small amount of dielectric grease to the new spark plug's threads. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use a torque wrench to tighten it to the manufacturer's specifications.
6. Reassemble the Bike
Reattach the spark plug cap, ensuring it is securely in place. Reinstall the fuel tank and seat, making sure all connections are tight and secure.
