Clearing a Kayfun Lite leak

[jakart]

I only got my kayfun this week, and I'm still getting the hang of the build and keeping the vacuum sealed so I've been having leaking issues. It occasionally leaks liquid out through the airhole. What I'm wondering is, is there a way to clear the leak without emptying the tank and taking it apart? I've tried blowing through the mouthpiece or the airhole, and sucking. Not much success, and actually a mouth full of fluid doh. Is there a way?

wipe away as much excess as you can, turn it upside down, vape gently through the airhole a few times (I suggest not getting complete coverage over the airhole, leave some room for outside air, you don't want to pull through that hole with a super strong suction and pull more juice through it and into your mouth). repeat as needed.

This happened to me my first time, turned out one of my o-rings was seated a bit off when I threaded everything together, double check that all your threads are going together smoothly and completely with no uneven spots in the exterior of the tank when fully threaded down.

Hope this helps.

Assuming all o rings are seated properly and that parts are already tightend down, what I do is to hold my device horizontally with airhole facing up, fire for a while and vape. No juice wasted. If you draw too hard, more vacuum will be created and the same problem occurs. So try not to draw too hard on kayfuns.

I have always used cotton on kayfuns and would occasionally get the leaks from the airhole, especially if I do not vape from it for the whole day. But since using ekowool, the leaks have never happened. BUT, I have to draw harder to avoid dry hits with ekowool.

So, I suggest varying your draw strength first to see if it solves the leak after clearing the airhole of juice.

There is a known issue with the kayfun clones the insulator on some are not centered over the mounting hole look at the positive post that's the larger of the 2 binding blocks. there is a white insulator under the larger one see picture

look for a gap like this picture below shows yours may not be a drastic as I have this one pictured this pic is for reference but look for this gap on both side of the insulator

to fix this loosen the screw on the bottom of the 510 connection and slide the positive block ove till the insulator coveres the complete hole through the deck. and retighten the screw
here is a pic with the block removed

this is how it should look when its fixed no more gap

What is happening is when you draw air into the chimney through the center vent ole under the coil its sucking juice down into the gap and leaking through the vent. This is not on all clones only some I have had to deal with and fix for folks.

Set up upside down and let it drain. As long as the top o-ring isn't the leaker, it will clear it out. It is the one position they shouldn't leak in due to siphon.

Pictures showed up while I was writing this. I haven't seen that one yet! It seems like every one I buy needs some fiddling, though. The last few had leaky o-rings. Before that it was a stripped screw, stripped fill screws, etc.

I'll check out that insulator issue once this tank is done. It only leaks when I leave it unused for awhile so maybe that's just something I shouldn't do.

ONe issue I keep having is that it's hard to remove the kayfun from my nemesis without some part of it loosening up and messing with the vacuum. I'm starting to think this is why people have a lot of mods. I just have the one and I'm always switching the kayfun with my RDA.

That's why I swear kayfuns are alive and have a personality of their own. ;-)
If I ignore them and use other toppers, they will start to weep and leak. Not every time, only happens when my last draw on it was too hard. Creates too much vacuum and too much juice gets into the chamber. Try to draw/suck softly for the last draw. May solve the issue.

I just turn mine upside down, hold a paper towel to the air inlet and blow through the drip tip, some liquid will come out - once it stops wipe up and resume vaping.

Ahah! This sounds like your problem if you ask me (which to be honest, I've only had mine about a week, but I sure did do a lot of reading on it beforehand lol!).

If it is coming lose in the body of the kayfun when you are taking it off your mod it sounds to me like the body isn't getting fully tightened and sealing the vacuum. I would completely disassemble it, I mean completely, screws, O-rings, everything, clean it up real nice and purty, and put it back together slowly and meticulously, paying special attention that the O-rings set level and uniform all the way around at the bottom most part of each body cylinder. My O-rings were not uniformly seated when I first got mine and it was a problem with my first filling. After doing the aforementioned process I have had no issues (albeit holding it out the window at 80mph in an attempt to cool it down after it had been sitting in the sun for a few hours, which spewed half the tank on the side of my truck )

Best way to clear the leak is to turn it upside down and blow. This makes sure you aren't blowing more liquid through it as the liquid is away from juice channels. My first build leaked but then I used a bit more cotton and a 10 wrap 29 gauge micro keep the cotton far away from the air hole. Also don't have the draw too tight or you suck up too much liquid.

Turning it upside down and blowing seems to do the trick. And yeah I'm going to disassemble it completely today and make sure all the seals are good.

Mine didn't have a o-ring in the chimney so I added one. My biggest problem was the amount of cotton I was using. And now I put it in and like to blow on it to fluffen it up a bit. Then I juice it and place it where I want and then rebuild it. Just rebuilt yesterday and no problems again.

This is great info can't wait til mine arrives. Thank you to all.

I have a question on the last picture. It looks like the blocks are touching. Is that okay? I did notice that mine looked like the second pic, but I thought that was how they were supposed to look, separated from each other.

This is what we do to clear a flooded cartotank. I think it was Rip Trippers who described the Kayfun as a "cartotank on steroids", so perhaps it is fitting. Both work on the vacuum/negative pressure system.

Just like a cartotank, overfilling can cause leaking. They need an air pocket to create negative pressure.

The only time I experience leaking with my KFL+ is when the juice level gets really low. I presume the negative pressure within the tank is upset.

You know, in the end it turned out to be a problem with a small wick. I took it to my b&m and told the guy it was leaking. He pointed out that if it was only leaking through the air hole then my leak had to be caused by a wicking problem. I put in a larger wick and no problems since

The wicks can cause a small leak on kayfuns the way you describe. I have had wicks that sat on the build deck near the air hole leak a little on me. What was happening is the juice in the wicks would start to leave the wicks and pool on the block near the airhole. So after a while of sitting juice would collect in the air channel. Well I guess leaking wouldn't be accurate, more of a flooding of the air channel as once the wick would dry out a little it would stop. Just make sure when you wick it that the wicks come out away from the build deck a little, it was more of a problem when I was testing out fewer wraps on my coil.
