1. Prepare Your Bike

Ensure your TTR230 is on a stable surface and the engine is cool to the touch. Disconnect the battery to prevent any accidental electrical shorts.

2. Remove the Seat and Side Panels

Use a screwdriver to remove the screws securing the seat and side panels. This will give you access to the engine and spark plug area.

The spark plug is located on the right side of the engine. You may need to remove the spark plug cap by pulling it gently to expose the plug.

4. Remove the Old Spark Plug

Attach the spark plug socket to the ratchet wrench and carefully unscrew the old spark plug. Be cautious not to damage the threads in the cylinder head.

5. Install the New Spark Plug

Apply a small amount of dielectric grease to the threads of the new spark plug. Carefully screw it into the cylinder head by hand to avoid cross-threading. Once hand-tight, use a torque wrench to tighten it to the manufacturer's specifications.

6. Reattach the Spark Plug Cap

Push the spark plug cap back onto the new spark plug until it clicks into place, ensuring a secure connection.

7. Reassemble the Bike

Reattach the side panels and seat, securing them with the screws you removed earlier. Reconnect the battery.
