The answer to your question hinges on what the end result of the noped is to be. Keeping it all stock? Keep the pump. Kitting, pipe and other performance mods or upgrades then ditch the pump.
The Japanese pumps on hondas, suzukis and yamahas are indeed bullet proof but they all err on the rich side of injecting oil (More oil than what is really needed). With more oil comes more heat and carbon deposits (not good on a modded motor). Also, a performance motor will tune better with premix being more precise.
