Step-by-Step Guide

1. Prepare Your Bike

Ensure your Yamaha TTR110 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by gently pulling it off the spark 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 spark 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, apply a small amount of anti-seize compound to the threads if desired. This helps prevent the plug from seizing in the cylinder head. Carefully thread the new spark plug into the engine by hand to avoid cross-threading.

4. Tighten the Spark Plug

Use the torque wrench to tighten the spark plug to the manufacturer's specified torque setting. Over-tightening can damage the threads, while under-tightening can lead to poor engine performance.

5. Reconnect 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.
