Breaking in a Mabushi Tamiya Motor silver can. 

Here my method I use for breaking in brush motors. Now there is a great chance I’ll get some feedback and that’s ok someone out there may have even a better way let me know.
1) I run the motor dry with a load 4 minutes
2) run the motor with a few drops of Zubak speed Juice on the commutator for 8 minutes
3) Run the motor in water for 8 minutes
4) blow dry 100% with air compressor and the spray motor with motor cleaner/break cleaner Let dry out
5) oil each end of the motors bushings. I oil the bushings while motor it running @ 2 volts.
5) put back in the car to race.
