Hi,
On a EVO III, I don't know because I've never run a stock motor in it. (In fact, I've not even run it yet.)
In a TA-04R, I used to run between 6.2 to 6.5 on a tight track. Used Tamiya B2s mainly. No specific break-in for the motor.

What kind of gearing do you use with the 23 type-T on your track. Do you use Tamiya tires too? Any specific breakin needed on the type-T?
