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 is located on the right side of the engine. Remove any obstructions, such as the seat or side panels, if necessary, to access the plug easily.

3. 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 wear or damage, which can indicate engine issues.

4. Install the New Spark Plug

Apply a small amount of anti-seize compound to the threads of the new spark plug. This will 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 plug to the manufacturer's specifications, typically around 18 ft-lbs.

5. Reassemble and Test

Reconnect any parts you removed to access the spark plug. Reconnect the battery and start the engine to ensure everything is functioning correctly. Listen for any unusual sounds and check for smooth operation.
