17 - FUEL TAPS The tank has two outlets with on and off taps that release a flood of fuel to the fuel hungry carb. The rider will have only one tap on until they reach the start line, and then you will see them open up the second tap to allow maximum flow while racing. When the race is over you will see them turning one of the taps off also. These taps must be closed after the race when parked, to avoid internal damage of the carb.
