ball bearing in the dump chamber

[skyless]

I have read a few things about how to make a classic valve more efficient. I have thought about getting it on a lath and removing the weld holding the powertube on but i dont want to ruin my valve trying that. So the next would be to put something in the valve to make the dump chamber smaller, I read that you can put ball bearing in there to do it. Do i just put them in the little hole that i can see when my on/off is removed? Or do they goin in throught he power tube front? I dont want them to be falling out at random either. Anyone fill me in on this technique?

No

Using a devoulmizer in the dump chamber is the way to go. Are you trying to make it more efficient on 12gs?

Yep that is the plan.

A ball bearing in the front air chamber could become a projectile. It probably wouldn't come out past the bolt stem, but it could cause operational issues if it gets in the powertube.

I would use a ring of some sort if I were making the volume smaller. Make it to fit inside the chamber and put it in through the front once you have the powertube removed.

just get a pre welded one, and unscrew it. It takes a little muscle, but is doable.

Then what would you put in it if you have one that unscrews?

A stack of brass or stainless washers would work. Any other metal may create corrosion/rust

Yep. What ^ said.

How do you tell if you have a "pre welded" valve?

I've been looking for one without luck. I saw a hypervalve pass through which I believe has a reduced chamber already, but no lvl 5 or 6 yet.
Any chance you have any Mann, when u use the word "just" , makes them sound easy to come by.

I've got one...

But it's in Cali and I'm not...

I use to have a few, but sold them. I am not sure on how common they are. All xvalves unscrew.

You can see if the edge is welded or not. That is the only way I know of.

i have three 6.5 valves.... one day i will get some washers and do some tests...
