I'd stick with the stock motor and just use an 11.1 lipo and a MOSFET. That will significantly increase your ROF and trigger response.
I don't totally disagree, but don't mess around in the GB unless you know what you are doing. KWA guns are pretty good out of the box. If it was a cheap gun I'd agree more about shimming. As far as the AOE goes, if it looks bad, try to correct it but you most likely only need to do a little filing on a tooth or two.Dont forget to shim the gears properly, and correct the AoE. Otherwise that 11.1 will turn it into a very efficient shredder
That makes zero sense, at all. Sorry for being blunt, not doing it on purpose but that's how I am sometimes.I don't totally disagree, but don't mess around in the GB unless you know what you are doing.

Installing an 11.1 will make things wear out faster but it's not going to be destructive (as long as you don't mess with the internals). Depending on how often you play and how aggressive you are with the trigger you could run an 11.1 lipo for a long time with out a MOSFET. I don't specifically suggest it but it's totally possible.
One thing people don't often mention is that you should decompress your spring after using an 11.1. You can do that by either releasing the quick change spring guide if you have one or by firing a few shots (mag out) with a 9.6 or 8.4 volt battery.
Your AEG is a best case scenario running an 11.1V li-po without a mosfet. I have seen a worst case scenario, the trigger switch literally melted, this was with a dinky little Firefox 11.1V 20C 1200mAh li-po. If the motor pulls a moderate current, you don't spam semi auto and have good trigger contacts you can run an 11.1V li-po without a mosfet for a long time before needing new trigger contacts. This is why many JG and CYMA AEG's can run an 11.1V li-po without issues, because they have low stress setups with relatively strong internals.We're talking about a KWA gun, they have strong motors and good internals and factory shimming.
I know filing teeth isn't correcting the AOE, and I know it's called overspin. But rather than explain overspin I just decided to tell the OP how to prevent spring issues caused by overspin. And there is a good chance the AOE is pretty good or at least good enough.
I'm not saying doing all the work isn't worth it, I'm just saying if he wants instant results he can just plug in a lipo. Granted, if that is the route he decides to go he has to understand it may require maintenance sooner than if he used a different battery.
There are several reputable YouTube channels and other players that say basically the same thing.
I currently have an m4 that is put together with random parts (nothing inside the GB is "performance"). I use an 11.1 2200 mAh 25c lipo and I don't have a fuse or mosfet, I removed one tooth on the piston to stop some rubbing. I've used the gun every Saturday for almost 6 months (about 4k rounds per game), I opened it last Sunday and the trigger contacts and other internals are perfectly fine.
I'm not suggesting the best method just just in my opinion the easiest answer to the original question. If he is a proper gun owner and performance regular maintenance on his gun and doesn't abuse it he won't have major issues.
If the OP puts an 11.1 in his gun (no mosfet) and destroys it within 6 months I'll pay to have it fixed.
