Step-by-Step Guide
1. Prepare Your Bike
Ensure your 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 free. Inspect the old plug for any signs of wear or damage, which can indicate engine issues.
3. Install the New Spark Plug
Apply a small amount of anti-seize compound to the threads of the new spark plug. This will make future removal easier. 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 plug to the manufacturer's specification, typically around 18 ft-lbs.
4. Reconnect the Spark Plug Wire
Firmly push the spark plug wire back onto the new spark plug until you feel it click into place. Ensure it is secure to prevent misfires.
