First thing , i changed in my KA was the piston and gear set, its not necessary but I've had problems with KA Pistons stripping or breaking quite a lot, still have not had my prometheus piston break in any gun yet. In my Opinon and some other people might agree on KA motors kinda suck compared to others so maybe swap it out for something else, most of my guns run a TM EG1000 <--- one of the best motors ever made in my opinion, or a G&Pm120.

I also run a Systema Magnum Motor in my primary set up.
