I did hear that 5-6 amps is more optimal though. Do I need to put this motor on an analyser and get it dialed in more? Thanks for the input in advance.
When you are running unloaded and pulling 3.45 amps you are going to have to gear higher than someone running the same motor pulling 5-6 amps. But, their motor will produce more heat and the efficiency will not be as good as yours. If you have a motolyser you can plot an rpm vs amp draw graph to find what timing is the most efficient. Every time I do this I find that when a motor is pulling 5+ amps unloaded, the amps are going up a lot more than the rpm. I'm going to summon

lot more detail if you want.
