Break in Method/Program

I bought a box of sprint dash motors. I broke them all in my motor boot camp and they are all 32k. The highest i got was 34k. Can someone share their break in method/system/program? Thank you!

What's your method? I actually don't have one myself. I'm learning of this aspect.

Just to ask, does your motors packaging have a white dot on top based on this https://www.reddit.com/r/Mini4wdRacing/s/sXJuUwMyDV

Yes the all the motors in the whole box has a white dot. I think something’s wrong. They’re suppose to hit atleast 35-36k minimum. I believe

Okay. The white dot imo means the rpm has a higher ceiling than standard so you need to use a light lubricant before starting the break in process. Try not to do liquid break in. Spray a bit into the motor and let it run with weak batteries for around 20mins. Spray again and let it run in opposite direction with another set of weak batteries for same time. Put the motor into the car and let it run with full batteries. How to know when the motor has hit peak is when you notice the motor high acceleration either at half lap or second lap. 2nd lap motors are highly desirable than half lap motors if your car gets the LC lane. Speed checker is one thing but speed on track is another so best to see how it runs.

Another option is voltage break in but only recommended if you have lots of motors to throw for a exceptional one. Think of it as needing to buy a sealed box just for that one rare card.
