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 battery to prevent any accidental electrical shorts.

2. Remove the Seat and Fuel Tank

Use a wrench to remove the bolts securing the seat. Once the seat is off, carefully remove the fuel tank by disconnecting the fuel line and any electrical connectors. This will give you access to the spark plug.

3. Locate and Remove the Spark Plug

The spark plug is located on the right side of the engine. Use the spark plug socket and ratchet wrench to carefully unscrew and remove the old spark plug. Inspect it for any signs of wear or damage.

4. 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 the torque wrench to tighten it to the manufacturer's specifications (11 ft-lbs).

5. Reassemble the Bike

Reattach the fuel tank and seat, ensuring all connections are secure. Reconnect the battery.
