Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike is on a stable stand and the engine is cool to the touch. Disconnect the battery to prevent any accidental electrical shorts.

Use the appropriate tools to remove the seat and fuel tank. This will give you access to the engine and the spark plug area.

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. 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 misfires.
