Step-by-Step Guide

1. Prepare Your Bike

Ensure your TTR250 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 Fuel Tank

To access the spark plug, you'll need to remove the seat and fuel tank. Use a wrench to remove the bolts securing the seat, then carefully lift it off. Next, disconnect the fuel line and remove the bolts holding the fuel tank in place. Lift the tank off gently.

3. Locate the Spark Plug

The spark plug is located on the right side of the engine. You'll see the spark plug cap connected to the plug itself. Carefully pull the cap off to expose the spark plug.

4. Remove the Old Spark Plug

Using a spark plug socket and ratchet wrench, turn the spark plug counterclockwise to remove it. Be cautious not to damage the threads in the cylinder head.

5. Install the New Spark Plug

Before installing the new spark plug, apply a small amount of dielectric grease to the threads. This helps prevent corrosion and ensures a good connection. Hand-tighten the new spark plug into the cylinder head, then use a torque wrench to tighten it to the manufacturer's specifications (18 ft-lbs).

6. Reassemble the Bike

Reconnect the spark plug cap, ensuring it is securely in place. Reinstall the fuel tank and seat, making sure all bolts are tightened properly. Reconnect the battery.
