Kayfun lite+...flooding...help...

[Jawden]

sooo, i've been vaping for about 8 or 9 months. cant remember exactly. haha. wish i did tho. so i am by no means new to this. i began with drippers and have built many drippers and coils in these past months.

but i just received my kayfun lite plus from eciggity and i was so excited! i soaked it and washed it and had a go at a build on it. i did a micro coil that read out to about .8 ohms with 28g kanthal. threaded her with organic cotton (cotton balls) and made sure that the cotton was on the deck and not in the channels (according to rip trippers) haha. and primed the wick, gave it a quick fire, screwed the chimney back on...now heres where i might have messed up...i filled it up from the top. with the top part of the tank off, i filled it to about 1/8" away from going into the chimney and screwed the top on. i had the afc screwed in all the way. i backed out the screw to get the most airflow, screwed it on my astro and started vaping. first few hits were great! then i had to draw a little harder and heard the gurgling....i emptied my tank, rewicked with a little more cotton this time, and same thing! i did about 3 builds so far and all have flooded. is this user error? has anyone else had this experience? should i put the wick in the channels and not just on the deck???

any tips/tricks or suggestions are greatly appreciated!

able to add pics when i get home from work if that will help.

Try making sure it's all tight, all the O-rings are in it. fill it from the bottom? watch one of Phil Busardo's videos on the Kayfun or Russian. If your draw is too tight it'll suck more juice into the atomizer chamber (inside the chimney).. also make sure your coil and wick are up away from the air hole on the build deck. give it at least a couple millimetres space.

drain out the liquid. the put it all back together and refill it using the fill port at the bottom. The kayfun design relies on negative pressure to draw eliquid up into the coil, when you pour it with the top off you run the risk of flooding the chamber. If it's a minor flood issue you can always vape it from the airhole, but you'll get some liquid into your mouth.. if it's major flooding it will just be easier to redo it.

A couple of thoughts on what may be happening.
The small oring that is in the top cap that the top of the chimney goes through will fall out and when it does the tank can not hold a vacuum and the juice will run out into the coil/chimney area.
If the tank is completely filled up there will be no space for air which acts like a bladder.
The tank has to have a vacuum in an air pocket to hold the juice in the tank. When you inhale you create lower pressure in the chimney area and juice flows into it. When you stop inhaling the negative pressure (vacuum) in the tank pulls any extra juice from the chimney area back into the tank. The pressure difference acts like a check valve.

Since this is going on here, and isn't over 600pages..

I've had a few successful builds on mine. I'm following the manual on problems and so forth. My coil is ~2mm above airhole, my wick isn't compacted in the wells just laying over them..tried leaving them open just getting them close to them too, my top oring grips so well, I sometimes unscrew chimney when removing top, and I've tried unscrewing top and tipping over screwing it back on.

Don't know what's going with it..

 

[Jawden]

thank you all for the responses!!

so, i noticed a few things.

one, my oring that slips onto the chimney does have a little play to it. maybe its not creating that vacuum?

two, i did fill it to the top...also FROM the top. so i'll have to fill from the bottom next time.

three, my coil sits about 1mm away from the deck.

i'm trying to get a picture of it. but i cant seem to get the sleeve that threads onto the deck off at the moment. hahaha.

When you fill from the bottom, tilt it to about a 45 degree angle with the top down and the bottom up and the fill hole at the highest point and only fill it up to the point that you can see just a small air bubble at the top of the glass section of the tank. That will fill it about 75% full and leave plenty of air in the tank.
If you fill it until you can not see an air bubble, you do not know how full you have it and can over fill it.

And if I'm using the SS tank? ......hahaha.

 

[Jawden]

Here's my build on it. less/more wick needed? Raise coil off deck more? or do you think it was just cuz I filled from the top?

 

[Portertown]

You got me with that one. I have often wondered the same thing. I guess you could use a 6ml syringe and put maybe 2.5ml in it. But that would only work when you knew the tank was completely empty.

 

[Jawden]

Also, just noticed my top cap o-ring ( the one that threads onto the tank section) looks like a small section has been frayed. It doesn't leak. But could that be a potential air leak?

It is a little hard to see in the picture, but it looks like the cotton is not quite touching the lower deck. I call the part that the juice channels run up to the lower deck. I call the part under your coil the upper deck.
If the cotton is not touching the lower deck it will not be able to wick correctly and suck up the juice being pulled in by the inhale.
I turn my coil at an angle instead of straight across between the mounting screws. This puts the cotton at the end of the lower deck and I leave it long enough that I can fold it over and bring it back under laying on the deck. This gives you more cotton to wick the juice.
There are some videos on YouTube showing this.

It could be enough for a air leak. Do you have any spare orings?

Yeah, my mistake. They're touching the lower deck. Not the top deck. I'll try that tho. Thanks!

And yes, I have spare o-rings.I'll change it as soon as I get home.

I'm tired and haven't read all off your replies, but I noticed something missing from your OP.

You said that you filled the tank from the top, but never mentioned covering the air intake with your thumb. Not covering the intake will allow the juice to displace the air in the coil chamber, ergo, flooding. If you haven't already, cover the air intake hole as you fill from the top. Thread the top cap on just barely. Turn the whole thing over and remove your thumb. Finish turning the top cap until it is hand tight WHILE THE ENTIRE UNIT IS UPSIDE DOWN. Install on device and continue to vape your face off.

Hope that helps.

i stated that the afc screw was screwed in all the way. but not sure if that was enough to help. i'll try filling from the bottom first like others have suggested tho. then atleast it'll take the top-filling issue out of the equation. just to be safe. thanks tho! maybe in the future i'll give it a try!

sorry, it was late and i was packingup to leave for work which resulted in a rushed reply. but the wick sits on the lower deck. after i screw bottom section of the chimney on i take a paperclip or something of that nature and make sure my wick blocks the channels so that no free flowing juice will seep through. but i think its a vacuum issue. either that or its just wicking so efficiently, its over-wicking...not sure.

 

[gypsymage777]

You do not want to block your channels. Make sure no leaks as everyone is saying. Put the tank together without chimney, cover holes and blow. No air should be lost. Do the same with the chimney. I got a knockoff first, then a Tobeco. The knockoff flooded like crazy, found out it was leaking between the bottom of the tank portion and deck. I replaced the bottom O-ring on the deck on the knockoff with an extra Tobeco one and no leaks, no flooding. Make sure that coil is 2mm above the airhole at least. I spent a little more than a few hours trying to resolve the same issue. It sure sucks rebuilding only to take apart and waste all that juice . It is all about that seal. If it does not pressurize correctly, it will flood. If you block the channels, it will dry hit.

 

[KurrptSenate]

You can fill from the top but you will have flooding issues at the beginning.

What I do when I fill from the top is place tape over the holes to help a bit, then as I'm screwing the top cap on, i give it a couple turns and flip the unit upside down. after i'm finished putting the unit together, I'll hold it upside down and blow through the drip tip. this will clear the chamber which will expel through the air intake hole.

2 times max of doing this and you'll be ready to rock

An easy way to ensure you don't overfill the KFL is to use a syringe, Place the syringe empty into your fill hole and draw up your old juice to ensure it is empty, do what you will with the old juice then fill your syringe to the 4ml mark this leaves you a half ml play. Gentley squirt the juice via syringe into fill hole. You now know exactly how much juice you have in your tank!
