Step-by-Step Guide

1. Prepare Your Bike

Ensure your Yamaha TW200 is on a stable surface and the engine is cool to the touch. Disconnect the battery to prevent any accidental electrical shorts.

2. Locate the Spark Plug

The spark plug on the 2015 Yamaha TW200 is located on the right side of the engine. Remove the spark plug cap by gently pulling it off the plug.

3. Remove the Old Spark Plug

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

4. Inspect the Old Spark Plug

Check the old spark plug for any signs of wear or damage. This can provide insight into the engine's condition. If the plug is oily or has excessive carbon build-up, it may indicate other issues.

5. Install the New Spark Plug

Apply a small amount of dielectric grease to the threads of the new spark plug. 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 18-22 ft-lbs).

6. Reattach the Spark Plug Cap

Firmly press the spark plug cap back onto the new spark plug until it clicks into place.
