I agree with hyde whyte , just remove the supply line from the fuel rail and turn your key on I'm not sure if your bike has time out switch on the pump, which will only let the pump cycle for so long without the pressure switch shutting the pump off? If it does time out, just turn the key off and cycle the pump again until it's drained, you might want to hook a charger to the battery though, keep in mind if you do hook a charger up , be careful not to touch the charger clamps, you don't want any kind of sparks around gas fumes!!
