Drain fuel tank on Yamaha TTR125?

To drain the fuel tank on a Yamaha TTR125, first, ensure the bike is turned off and cool. Locate the fuel petcock (valve) on the side of the tank, turn it to the "OFF" position, and disconnect the fuel line from the carburetor using a wrench. Place a container beneath the tank to catch the fuel, then turn the petcock to the "RES" or "ON" position to allow the fuel to drain completely. Dispose of the fuel properly and ensure no spills occur.
