If it is damaged so I can do a quick turn around when gear box is open which brand of pistón head do you recommend is a good solid one?
Compatible 12:1 gear set
So I have a question I want to increase my RPS on my classic army X9 I want to change my gear set I currently have 18:1 stock I know CA makes things pretty proprietary I currently have a ZCI TpA 22 motor with a vallen 2000 MAH 15/25c battery I would want to know if anyone has changed their gear set for the nemesis x9 that will work

Whoops I forgot you're already planning on swapping your gearset. By all means dig in your gearbox then, problem could be anything. But I would still recommend purchasing a good spring later on down the road; for now, if it ain't broke, don't fix it. 
It’s ok I still need all the feedback i Can get so all this is helpful especially with brands what to stay away from Im still learningWhoops I forgot you're already planning on swapping your gearset.

If the oring is not visually damaged (torn, etc) you can test compression by pulling the piston + cylinder & cylinder head out of the gearbox, putting your finger over the tip of the cylinder head, and trying to ~abruptly push the piston into the cylinder. If seals are all good, you should not be able to push the piston all the way in - if bad, air will leak past the seals and the piston can be pushed all the way in. How easy the piston can be pushed in indicates how bad the seals are. Note that this tests the piston and cylinder head seals - inspect both if there's a leak.
Ok I’ll check it did smell a little off like something was burnt or something you guys are right I need to open it upIf the oring is not visually damaged (torn, etc) you can test compression by pulling the piston + cylinder & cylinder head out of the gearbox, putting your finger over the tip of the cylinder head, and trying to ~abruptly push the piston into the cylinder.

Now if I do find a something damaged like the piston, piston head what brand should I go with? I don’t want to keep buying brands that aren’t good like I stated I am going to be changing gears set so I’ll take that into considerationOk I’ll check it did smell a little off like something was burnt or something you guys are right I need to open it up
Lonex blue or red for the piston (blue recommended for regular builds, red is better for high power springs). Lonex POM piston head is generally accepted as the best.
Thank you and would it be recommended to get a Swiss cheesed piston?Lonex blue or red for the piston (blue recommended for regular builds, red is better for high power springs). Lonex POM piston head is generally accepted as the best.
I’m just asking all these questions so I know what to get when the time comes
Yep, that's the Lonex Red. There's a Blue version as well, same design but it's made of different material. I've run both in DSG setups with an SP140 spring (~m175 w/ a half stroke), neither has had issues. Polymer pickup tooth is preferable IMO as it's easier on your gears + any wear will just improve AOE
Now I do notice that has less teeth and here’s a noob question that will be compatible with 13:1 gears correct?Yep, that's the Lonex Red.

It depends.
Your 12:1 should be a set. How that set matches up to another set depends.

Ok because i want to go with the Shs 13:1 gear set and rm105 recommended the lonex red pistón so i was just wondering if those would be compatible with the 13.1 gear setIt depends.

Also the same stock cylinder would work just fine or would I need to change that out as well?Yea sir and perfect thank you guges appreciate all the help
And also my stock bearings are ball bearing should I leave those stock ones in or change them with regular bearings?Also the same stock cylinder would work just fine or would I need to change that out as well?
There is no need to change the stock Cylinder. What would you change your stock bearings too? Bushing? Sure...but it depends.
As a general rule bushings are more reliable, but bearings should be fine for your purposes.
