Tools and Materials Needed

  • Spark plug socket wrench
  • Ratchet
  • New spark plug (NGK CR6HSA recommended)
  • Torque wrench
  • Dielectric grease (optional)

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 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

Take the new spark plug and apply a small amount of dielectric grease to the threads if desired. This can help prevent corrosion and 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 spark plug to the manufacturer's specifications, typically around 7.2 lb-ft (10 Nm) for the TTR110.

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.
