Step 1: Prepare Your Bike
Ensure your Yamaha YZ125 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire to prevent accidental starting.
Step 2: Remove the Old Spark Plug
Use the spark plug socket wrench to carefully remove the old spark plug. Turn counterclockwise until it is loose enough to remove by hand. Inspect the old plug for any signs of damage or wear, which can indicate engine issues.
Step 3: Check the New Spark Plug
Before installing the new spark plug, check the gap using a gap tool. The correct gap for the 1976 Yamaha YZ125 is typically around 0.024 inches. Adjust if necessary.

Apply a small amount of anti-seize lubricant to the threads of the new spark plug. Carefully thread the new plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up – do not over-tighten.
