Step-by-Step Guide
1. Prepare Your Bike
Ensure your WR250F is on a stable surface and the engine is cool. Disconnect the battery to prevent any accidental starts.
2. Remove the Seat and Fuel Tank
Use a wrench to remove the bolts securing the seat. Once the seat is off, carefully remove the fuel tank by disconnecting the fuel line and any electrical connections. This will give you access to the spark plug.
