Will a KB45L 2300KV motor overheat on 4S lipo in a 4.3Kg e-savage? Assume that it is geared for slightly over 40mph (around 25T)

I have one new kb45 motor but I am not sure if I should just get a HW150A for use with it or should I get a MMM/CC Neu combo.

It should be alright, but watch temps closely. I'd get the MMM to run the kb, and upgrade to a cc neu if the kb fails.

Some pictures of my KB45 L can 2300KV

The rotor looks pretty well made.

The shaft has been ground down to 5mm.

how did you grind down the shaft?

They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.

Did you simply unscrew the front endbell?

How tough was that?
