Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • New spark plug (NGK CR6HSA recommended)
  • Torque wrench
  • Anti-seize compound (optional)

Step-by-Step Guide

1. Prepare Your Bike

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

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 damage or wear, 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 by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten it to the manufacturer's specification of 9.4 lb-ft (12.7 Nm).

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 secure to prevent misfires.
