Step-by-Step Guide

1. Prepare Your Bike

Ensure your TTR110 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it off the spark plug cap.

2. Remove the Old Spark Plug

Use the spark plug socket wrench and ratchet to carefully unscrew the old spark plug. Turn counterclockwise until it is completely removed. 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, 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. Once hand-tight, use the torque wrench to tighten it to the specified torque setting (usually around 7.2 lb-ft).

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.
