Kayfun lite clone

[themelody]

So i got this Kayfun lite clone about 3 weeks ago from fasttech, and it keeps leaking through the single air-hole it has on the bottom side of it. Has anyone else had these problems? If so, is there a fix for it? I'm sure this has been asked and answered somewhere else on this site and if so please just post the link to that post about this.

This has just been killing me, it works so well! Up until its about half way maybe 2/3 of the way empty, then it just comes out of the air hole. Also i feel like this is relevant but it just happened which made me post on here about it(lol). Right before it started happening i kind of dry hit it(hit it without firing it) in order to show a friend how to hit it properly, could that have sucked to much liquid into the wick chamber which made it make its way to the air hole? Or does it just have something to do with the pressure going down?

I am new to rebuildable tanks and to kayfuns, so im not sure, no one has told me yet atleast, if they are the type of tank that will leak once they get so low due to loss of pressure inside the tank.

I'd appreciate any help that anyone can give me, link or not.

Thank you,
TheMelody

My KFL is hiding in a box. There are plenty of people here that will tell you how good it is though. I'm starting to believe that most of them are paid to say it. So, I'm not sure if I can believe any of them about anything, anymore... I guess I need to start writing all their names down so I can refer to the list in the future.
Congratulations getting off the analogs. And welcome.

Make sure you've got a good seal. Check the tank and especially the top cap to make sure you're missing any o-rings.

What does this mean? You have multiple KFL that have issues? clones authentics? what's the problem with em?

I think i might of just sucked too much liquid into the wick chamber when i dry-hit it for my friend...lol Once i blew into the mouth piece to get it all out through the airhole, its not leaving anymore. I had problems with the threads not being completely sealed before, it leaked through the air-hole a bit, and also through some of the threads but i just put a little amount of vaseline on the threads and now it works like a dream.

Well rc3po, i can assure you that unfortunately i am completely unpaid by any company that produces any vaping equipment. I think the kayfun lite is one of the best things I've vaped up. I can't say I've vaped on a lot of rebuildable tanks, I've only used the kayfun lite, the smoktech rebuildable single coil, i think a castle? I'm not so sure, but like two or three other drippers from my local vape shop. the guy there lets me try out his drippers every now and then. I've personally only owned protanks, and cartotanks, plus other various tanks that didn't last long.

I've been vaping for a year now, and I feel healthier than my previous 4-5 years smoking cigs.

If anyone has any other ideas what would help this out, like one guy on the fasttech website said that he thought the channels that let liquid into the wick chamber are too deep and let to much in but didn't offer anyway to fix that issue. If someone knows about that and is able to offer the fix then that'd be awesome.

Thank you for your input,

check the small o rings in top of tank if they don't seal on the chimney air wiill enter and allow juice to flow out, same with and o rings in tank above where the juice is. also make sure chimney and it's top are tightened down as well as you can with your fingers. I never have flooding issues if the seals are good and the chimney is tight., hope that helps

 

[joesquid]

I'm certainly no expert but it sounds to me like you may have a problem with the bottom o ring on the plastic portion of the tank. When the juice level gets low it may be letting in air. I'd make sure it is tightened down and that the o ring is fine. There is a section on here for tech issues and one specifically for RBAs if that doesn't help. Good luck and welcome to ECF!!!!

Hi the kayfun is very particular to the build. First make certain you have about 2 to 3 mm Clearence over the air flow valve and your coil, second wicking is very important, I make sure my wick just touches the trenches of the chimney. I put the chimney on pull the wick through then tuck each side in. It will almost look like a pair of cotton lips with the coil in the middle then I top the chimney. Put the tank on. I close both air holes when I fill the tank then cap, turn it upside down and open the air holes, this pressurizes the tank, then I put the drip tip on. To make sure I'm not flooded, I take a paper towel and blow through the drip tip to make sure it's clear, once it's clear I vape then blow back into the tank and smoke should come out the air hole and tank should be pressurized. You should have no gurgling or leaking now if done correctly. Hope this helps. It works perfectly for me. Best of luck.

From Fasttech, its certainly possible there's an undersized, bad, or missing Oring. The KFL needs a vacuum and seal.
How do you fill it? Top filling can be done, but its kinda tricky and usually will leak a little untill the vacuum is stabilized.
The KFL is a darn fine RBA.

Well I'm mainly against clones. I haven't had an authentic Kayfun, but still the R91 is just better. I haven't used the KFL Plus so I can't rag on it. But I'll never buy one now - they should've built it right in the first place. Then the R91 would have been a "real" clone, instead of an improvement.
Congratulations for being off the analogs! It's been a year for me also.

I think all the seals are fine. I tried screwing in the bottom part in first(with the chimney and every attached) and did it really slow and i felt it hit the o-ring before it was half was screwed on, so im assuming its all good there.

Well Ill try to figure out how to seal it a bit better, but like i said i put vaseline on all the threads that connect the tank pieces.

I usually fill my kayfun from the fill hole on the bottom, i've heard it doesn't work filling it from the top. Like you can plug the air-hole but that its easier/better to just fill it through the fill hole.

I'll have to try your way of filling it realsis, hopefully it will work better.

I'm still thinking it was the dry-hit i took, but ill definitely try everyones advice.

Thank you

If it is leaking through the air inlet hole then you have an air leak in the tank someplace. Faulty o-ring or you don't have the tank tightened down good enough.

Also if it just a Kayfun Lite the leak might be coming from the fill screw and not the air hole. The Kayfun Lite + V2 has a recessed fill hole and a rubber washer around the screw for the fill hole.

I have 6 of them and none of them leak. But then I have the KFL + V2 model.

This... I've read about leaking due to a bad seal on the fill screw. I have read that a little teflon plumbers tape on the threads of the screw will fix it if that is the problem. I have two KFL+ v2 clones by EHPro and have no leaking issues.

 

[WharfRat1976]

My $0.02 is that the only way smoke juice comes out of the air hole is if it enters the air hole on top of the build platform. Therefore, The pressure of the tank is not keeping the smoke juice below the wick platforms as it should OR the wick is not burning the smoke juice fast enough and it is essentially falling back into the airhole OR the sides of your wicks are too close to the airhole and smoke juice is creeping into the air hole. Did I mention smoke juice...

Smoke your Juice?

So, basically this is where you ignore the normal English language and generally accepted terminology and make up your own so you can put down clones while admitting your favorite RTA is in fact a clone?

The Russian 91% did one thing and one thing only that was different, they drilled a hole and put a small threaded pin in it to make the airflow adjustable. Other than that it's a straight up Kayfun Lite clone, and making one tiny improvement doesn't change the undeniable fact that it is just a clone, a near perfect copy of a Svoemesto product.

You can gladly refer them to me. First thing I will state... The Kayfuns I have gotten from fasttech end up in the garbage. If you want a good KFL clone stick with Ehpro or Hcigar, everything else is hit or miss.

I have a total of five KFL.. Authentic and Ehpro. No leaks unless you don't fill,it properly, lose vacuum or you tear an o-ring.

 

[danca90]

Fill it with water, and see where it's leaking.
My eh pro kayfun only leaked once. When I tried to top fill it.

Top filling just never works out like you have it pictured in your mind. I did it for a while and found it be more of a pain.

 

[David1975]

I've got 2 Kayfun's, 1 lite+ from Ehpro and one 3.1 from Hcigar. I've had the lite+ leak if I tried filling from the top, never when filled through the bottom. The 3.1 has never leaked and I only use the fill port. IDK if it could help, but as a mechanic who works with hydraulics... I'll sometimes take parts and dip test them to check for leaks. Air will escape easier than liquid, so I'll take a part, hook up air too it and block all the other ports. If I see air bubbles under water..... that's where it is or would leak. Wonder if you couldn't close the air screw and do something similar to test the outsides for cracks or poor seals? I can tell you in my experience at work.... you can have a crack so small you can't even see cause BIG problems. JUST DO ADD TOO MUCH AIR. a little air will work.... you don't need to blow it up under water. I'd say 1-2 psi MAX should work.
