Tools and Materials Needed

  • Spark plug socket wrench
  • Ratchet
  • 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 the touch. Disconnect the spark plug cap by pulling it straight off the plug.

2. Remove the Old Spark Plug

Using the spark plug socket wrench and ratchet, carefully unscrew the old spark plug from the engine. Turn counterclockwise until it is completely removed.

3. Inspect the Old Spark Plug

Check the old spark plug for signs of wear or damage. A worn-out spark plug can indicate other engine issues. If the plug is oily or has excessive carbon build-up, further inspection of the engine may be necessary.

4. 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 can help prevent the plug from seizing in the engine. Carefully thread the new spark plug into the engine by hand to avoid cross-threading.

5. Tighten the Spark Plug

Use the torque wrench to tighten the spark plug to the manufacturer's specifications. For the TTR110, the recommended torque is 9.4 Nm (7 ft-lb). Do not over-tighten as this can damage the engine.

6. Reattach the Spark Plug Cap

Once the spark plug is securely in place, reattach the spark plug cap by pushing it firmly onto the new plug until it clicks into place.
