Step-by-Step Guide
1. Prepare Your Bike
Ensure your Yamaha TTR125L 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
Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is completely removed. Inspect the old plug for any signs of wear or damage, which can indicate engine issues.
3. Install the New Spark Plug
Before installing the new spark plug, check the gap to ensure it matches the manufacturer's specifications. Apply a small amount of dielectric grease to the threads if desired. Carefully thread the new spark plug into the engine by hand to avoid cross-threading, then tighten with the spark plug socket and ratchet. Use a torque wrench to tighten to the specified torque setting (usually around 18 ft-lbs).
4. Reattach the Spark Plug Wire
Firmly push the spark plug wire back onto the new spark plug until it clicks into place. Ensure it is securely attached to prevent misfires.
