NOTE: Please note that the motorcycle should be parked on flat ground, and the fuel tank should be as empty as possible before attempting to drain the fuel.
1. Locate the fuel drain bolt. The fuel drain bolt on the Suzuki Boulevard C90T is located at the bottom of the fuel tank, on the right side of the motorcycle. It is a 17mm hex bolt.
2. Place a drain pan under the fuel drain bolt. Make sure the drain pan is large enough to catch all of the fuel that will be drained from the tank.
3. Loosen the fuel drain bolt. Use a 17mm wrench to loosen the fuel drain bolt. Be careful not to drop the bolt into the drain pan.
4. Allow the fuel to drain. The fuel will drain from the tank and into the drain pan. This may take a few minutes.
5. Tighten the fuel drain bolt. Once all of the fuel has drained from the tank, tighten the fuel drain bolt. Be careful not to overtighten the bolt, as this could damage the threads.
6. Dispose of the fuel properly. The drained fuel should be disposed of properly in accordance with local regulations.
