firstly, what turn rating do your 540 motors have?
a 550 will have slightly more torque than a 540 (given both have the same turn rating)
Im guessing now you have a motor with to low a turn rating. that will burn them up real fast as they don't have enough torque and will always struggle getting up to max rpms. that constant struggle means lots more heat.
I had assumed before you had replaced with stock motors. LMK what motors you got.
