By direct comparison between experiment and theory with no adjustable parameters, we show how the classical fluctuations on a multistate atom laser beam increase with increasing flux. The fluctuations are inherent to state changing out coupling, rf, Raman, or otherwise and are likely to be present in all atom lasers, pulsed or continuous, that employ such out coupling. If not removed or avoided, these classical fluctuations will prevent shot noise limited measurement employing atom lasers of this kind.
