Can I get diodes that will drop 0.3-0.4v??? Are there different types of diodes?
Wrap thin wire around a nail to make your own power resistor, it will only take a few ohms to work. What you want to do is start with a long piece of wire and see how it works then keep cutting off some until you get it to work well. Then just wrap that around the nail so that it can get rid of the heat. R.S. use to sell a pack of rolls of high AWG wire, I don't know if they still do.

The only problem with this solution is that you just created an inductor, so whatever motor is hooked to the inductor will have current issues, especially if the motors are being powered with a PWM signal.
its definitely not caused by friction
Its not friction!!! im telling u one motor draws more current than the other, i used a multimeter to verify this with the motors running free

You have no way of telling what's causing the increased current draw, nor do you know if there are multiple competing effects here. I would be very surprised if the two motors experienced exactly the same frictional forceWell whether its friction in the motors or a different number of windings in the coils, the fact is it still draws more current....I think I actually do have hall effect conductors, might try thatcheers
