I'm going to try to make this as short as possible since it's a lot to say. I'm running out of ideas and just asking people I come across to see if they know what's going on. So I bought a used demon and it to frank for the 2013 upgrade. Got the new internals and changed my tank output to 500 psi. Aired it up once I got it to check for leaks and didn't get any. About a week later I aired it up to dry fire it a bit and got a bad leak coming from the top of the trigger by one of the adjustment screws. Pretty much every oring is new on the gun, I don't think its the transfer hole oring or the manifold since it's new and not damaged. When I got the leak I screwed the asa in and out a couple of times and after awhile the leak went away. Only thought is it's an oring that was out of place and went back in. The gun shot very quietly once the leak was gone but when it had the leak it shot louder than it's supposed to.

I noticed at one point that when I removed the bolt and put it back in the I got the leak. So I relubed the bolt with dow 55 and checked, didn't leak so I thought it was ok. Aired it up the next day to make sure it didn't leak and fully know that I fixed the issue, leaked again. Shot a bit to see if it would go away and it didn't, it just shot loud. Next I took the whole regulator apart to clean and lube it. When putting it back I tightened the adjustment screw all the way in and turned it out a turn and a half. Some tech videos I watched said this would get it to about 270. Still got the leak after that, however I only got it when I shot the gun and the leak was very light. Still from the same spot but light. I turned the reg adjustment screw a little bit more out or so and doing that got rid of the leak. All the orings are cleaned and lubed with no nicks, cuts, or scratches. Asked Frank and he even said it must have been an oring that went out and went back in. Understandable but why does it do it everytime than? As for now I can't air my gun up till next week since my tank has no air and I need to get it serviced.

My guess is if you look at pics of the new bolt you can see in the middle of the can 2 thin orings between 2 larger ones. There's a small piece that holds those orings and if you slide that to the other side there are tiny holes beneath it. My only guess is the leak is coming from those holes and the piece is supposed to cover it. It's possible since putting the bolt in it could slide back to expose the holes. Any ideas or demon owners who have the new internals know what I'm talking about?

On that shuttle (qev sleeve) there is a lip, which way it is pointing? towards the the front of the gun or towards the back of the gun? Leaks from the trigger frame are 9/10 a shuttle problem.

Well that's the thing, with the new internals for the demon there's no longer a qev

If you're just talking about the manifold assembly itself than idk which way it's facing. I forget which way it was facing when I first opened the gun. I'm not sure why the tech that put in the new manifold would put it in the wrong direction

The shuttle valve is what replaced the qev. It does the same job as the qev, it's just a more reliable exhaust valve. If you have it in backwards or if an oring on it is bad it would defiantly leak from that area I think.

I pretty much put it on the same way I got it. The first time I got the leak I didn't even take out the bolt or anything, which is why I'm confused about it. If I had a full manual to go by for the new internals than it would be easier

Sometimes they get put on backwards, this can cause a leak from the trigger. Take the sleeve off and put it back on the opposite way, use lots of lube because those 23x1 o-rings inside of that shuttle are very thin and get nicked on the threads easily. If the leak changes, replace those two 23x1 o-rings inside the shuttle.

I'll have to do that than. When I go to the shop to get a new ninja reg since I damaged mine ill mess around with the gun and lube those orings again and change the direction of the shuttle. If that's the only reason than ill feel like a dumbass haha but thanks guys ill let you know if it works out

It was the shuttle! Thanks guys

No problem man. Was the shuttle on backwards? what fix the problem? I'm just curious.

Yea it was on backwards which makes it funny because when I first got the leak I didn't even take apart the bolt yet. So that means whoever put the bolt drive in for me at vanguard, put it in backwards. Obviously now know that on the shuttle it has 2 orings, need to put the side in first that doesn't have an oring close to the edge of the shuttle.

At least now what I got out of that is a better understanding of fixing leaks on my gun, everyday service for my gun, and a fully cleaned/lubed reg and bolt
