1. Prepare Your Bike
Ensure your Yamaha YZ80 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it straight off the plug.
2. Remove the Old Spark Plug
Using the spark plug socket and ratchet wrench, carefully unscrew the old spark plug from the engine. Be cautious not to damage the threads in the cylinder head.
3. Inspect the Old Spark Plug
Examine the old spark plug for signs of wear or damage. A worn or fouled spark plug can indicate other engine issues that may need attention.
4. Install the New Spark Plug
Apply a small amount of anti-seize compound to the threads of the new spark plug if desired. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten the spark plug to the manufacturer's specifications (18 ft-lbs for the YZ80).
