For the most in preformance....just make sure your bearings are reamed and polished to a mirror shine....as well as the arm shafts....polish the living shintz out of them. This will lower the overall friction.

I have a lot of "people" in japan, so I can get those cut bushings....where they're all cut down and there's minimal material that is in contact with the shaft.

The key to stock motors is cutting down on the friction and resistance. After that, center the arm....brush face tuning...then spring tensions.

Stock motors would also cost less with bushings. If you have to put bearings in a stocker from the factory, you could easily add on 10 bucks to the price of your motor!
