i milled the shaft on my kb motor with a standard dremel bit. all i did was hook the motor up to the esc and spun it slow while grinding the shaft to 5mm with my dremel. all you have to do is eyeball it and check the size often with a 5mm pinion gear. then, all you have to do is grind the flat spot.
btw: you will need a custom motor mount. the kb motors have 30mm spacing and 4mm screw threads.
