Kayfun Lite Plus And Leaking/Flooding

[Whitechapel]

I got my legit Kayfun Lite Plus the other day but finally had time to sit down and build it tonight. And wow, what a vape! It'll only get better once I get my mech. However I have run into a couple issues.

1) When I hit it, I feel like I can taste juice on my tongue. No bueno. Someone said to open the airflow hole up but it's an airry hit already, so I don't think that is it. I did open it up more just to test, still found myself getting that juice taste on my tongue.

2a) It floods out the airflow hole like crazy. I lost a bunch of good juice tonight. I followed Pbusardo's tip to fill it through the top and not through the fill hole, but it still dripped out. If I held it to the hole was facing down, juice would drip out quick.

2b) When I do the top fill method, when it's upside down, juice flows out through drip tip hole. How do I stop this?

3) When I hit it, so I hit it like a Genny on autodrip mode and tip it sideways? Or?

1/2a your wick is too small
2b check the Oring on the inside that the chimney seats in. Remove drip tip and clean excess liquid from right there. See if it keeps happening. Both problems are possibly due to flooding, due to lack of enough wicking material.

Be sure chimney top is screwed onto it's cylinder tight. If not, it can loosen up when you unscrew the top off when filling NOT using the fill hole. This will cause a constant flow of juice into the coil area. ;-)

One other issue is if it's leaking out the drip tip when you fill it inverted using the screw hole, your juice bottle is making an airtight seal on that fill hole. You are pressurizing the device and making it leak. (or overfilling it) I prefer filling it with the top off myself. Unless I've got the plastic middle tank section on it. Easier to see when it's full that way.

Make sure your coil is raised, as much as you can get it, off the deck. I was having some leaking issues with mine the for the past day or so, when I rewicked it earlier today I noticed the coil was sitting a bit closer to the air hole than usual so I lifted it a bit and haven't had any issues so far.

Another suggestion would be to try to fill it through the fill hole as apposed to through the top as I hear you don't quite as easily get the same vacuum affect needed for the kayfun to work properly. I can see how with the original kfl someone might have issues filling with it but with the recessed fill hole in the kfl+ it is very easy to fill with every type of juice nozzle I have come across. I filled mine today with a dropper and although it took a minute it was mess free and as I just mentioned, leak free.

With the chimney, should I just be in the tip of the o-ring? So when the tip piece is screwed in it sits over the coil?

I've set up KFLs and KFL+ for quite a while now (have 3 of each), and there have been some great suggestions here so far. I'll add mine to the mix:

1) Folks have been saying for a long time that 'less is more' with cotton, and have basically traumatized people into not plugging those juice channels. I've found, and only recently did I get over the fear, that using MORE cotton actually helped with the flooding / leaking and had no negative impact on wicking. So I now have nice, thick tails laying over the full length of the deck, covering but not going into the juice channels. Works great, and flooding went down substantially.

2) Don't suck so hard. Lighter pulls, and give a little time in between each 3-4 toots.

3) Make your coils a bit longer (obviously adjust gauge to your taste) so that the cotton has less contact with the area where the air hole is under the coils.

4) KFL+ : was disappointed that they solved the leak problem on the fill screw, but then added another screw with no o-ring (the airflow screw) to seep juice onto my mod now. The plumbers tape / teflon tape fix as used for the fill screw on the KFL doesn't work as well with that tiny airflow screw, so I used Chap-Stick and that has sealed the hole for 2 weeks now with no seepage. First, clean and dry everything completely. Then take the airflow screw out completely, and coat it with Chap-Stick so you can definitely see some in the threads. Screw it back in a little deeper than flush, then 'cap it off' with another dollop of Chap-Stick and smooth it out flush. Since I never adjust the airflow, and this basically keeps it wide open (like the KFL), the Chap-Stick just stays there and keeps everything sealed up nicely. I was going to use Vaseline, but didn't have any in the house - I'm assuming you can get the same results with that if you wish and it's probably a bit easier to work with.

Just my 2 cents! Good luck!

I was helping a friend with his kfl+ the other day and every time I'd fill it.. it would leak out the drip tip. I rewicked it several times and it kept dripping. When set upright, it would continually leak out the fill hole. I figured out the problem. The plastic part was cross threaded. I snapped it together and was able to unscrew it and then screw it back together correctly.. leaking issue solved.

Also, I have another friend who I'm trying to help ..she complains of both leaking and dry hits. I met her at a restaurant and took it apart. The wicks were standing straight up! She has a VERY hard draw (golf ball through a rubber hose) and she obviously sucked so hard that she sucked the wicks straight up the chamber! I told her that unless she changes her draw, she probably won't be able to use the kfl.

So maybe you've got a section cross threaded or your just sucking too hard. Sucking too hard creates too much of a vacuum. Too much juice is pulled up into the chamber... more than can be vaporized.

Good luck!

Here's a list of problems and solutions from SvoeMesto

The problem: Kayfun Lite sloshing, flooding, liquid flows out through the duct hole.
First you need to check if the tank is airtight.
If the tank is not sealed, e-liquid will pour out of it into evaporation chamber by the
principle of communicating vessels, and then it will flow through the air duct.
Check if evaporation chamber (3) is firmly screwed to the base; all o-rings are in place and
intact: (1с), (3с), (4b), and especially - (4c).
O-ring (4c) is the easiest one to lose during disassembly/assembly.
Also make sure that the transparent window (3b) is not cracked in case you use it.
Also make sure that the screw (1l) in place and tightly screwed.
If you have verified that the seal is not broken, but the problem still persists - let's try to
find and eliminate the cause.
There may be several more reasons for leaks:
The reason: Wick is too long and/or coil lies too low over the air duct.
What happens: If the wick is too long and it takes all the available space in the
evaporation chamber, then, when swollen with e-liquid, it leans to the posts (1d) and (1e)
at the level of the air duct or even higher.
Liquid begins to flow from the wick to the poles and then into the duct.
In this case the duct becomes kind of extension of the wick.
The same happens when coil lies too low over the air duct - swollen with liquid wick can
stick out between the coils and touch the poles.
What to do: shorten the wick, position it correctly on the sides of the poles, lift coil higher
over the air duct.
The reason: With each draw, evaporation chamber receives more e-liquid than can be
evaporated; as a result e-liquid floods the evaporation chamber and flows through the duct
out.
There may be several reasons for this:
Reason number 1: insufficient heating temperature, or rather lack of power (voltage) to
the coil, when coil can’t heat up to required temperature
What to do: Increase the power (voltage) on the battery mod or build a coil with less
resistance.
Probably batteries are depleted - charge/replace battery if it is the case.
Reason number 2: Too strong/long draw
Try to inhale slowly and smoothly.
You need to get used to the lighter draw, especially if you are used to hard draws of
conventional cartomizers and tanks.
Find comfortable for your strength and duration of the draw that would at the same time
allow all e-liquid entering the evaporation chamber to evaporate during the draw and
Kayfun Lite would not overflow/slosh.
You will quickly get used to this type of draw and will get the most from your Kayfun Lite.
Minor leaks may also happen if the tank is filled completely, or it is filled more than halfway
while Kayfun Lite is lying horizontally or with mouthpiece tilted down for some time.
In this case, one of the grooves (1h) could be at the top "in the air" and another one at the
bottom dipped into e-liquid.
In this case the air will escape from evaporation chamber through the top groove and eliquid
will flow from the tank to the evaporation chamber through the bottom groove.
Naturally this process stops as soon as both grooves are covered with e-liquid.
Make sure that both grooves are always covered with e-liquid, keep Kayfun Lite horizontally
in such a way that the mouthpiece is always slightly higher than the evaporation chamber.
Even better, keep it in the vertical (or near vertical) position if your battery mod allows it.
Leaks may also happen when ambient temperature and/or pressure changes abruptly, for
example when you walk into a heated room from the cold or in an airplane during
takeoff/landing.
It may even happen during rapid ascent/descent in express elevator.
Solid (metal) parts of the device are expanding/shrinking with temperature/pressure
change, changing the volume of the tank and causing e-liquid to flow into the evaporation
chamber.
Pressure drop causes the process similar to what happens when you draw, just without
heating the coil.
To avoid leakage in such cases we recommend you to keep/transfer Kayfun Lite upside
down i.e. mouthpiece down.
In this case, grooves (1h) will be at the top in the «air bubble» and when the temperature
or pressure changes, air will flow between evaporation chamber and tank instead of eliquid.
The problem: Burnt taste. This problem is opposite to the leakage. Dry wick is the most
common cause of burnt taste.
The reason: Too high heating temperature, to be exact - excessive power (voltage) is
applied to the coil. This heats up the coil above desired temperature.
What to do: reduce the power (voltage) on the battery mod or install higher resistance
coil.
The reason: No liquid left in the tank.
What to do: Refill the tank
The reason: Tails of the wick are packed too tightly in the evaporation chamber.
What happens: Too tightly packed wick may block grooves (1h) and obstruct e-liquid flow
from the tank to evaporator chamber.
What to do: Place wick properly.
It must lie free over the grooves (1h) but should not be pressed against or stuck into them.
The reason: The grooves (1h) are blocked
What happens: Pieces of wick are stuck in grooves (1h)
What to do: Remove pieces of wick from grooves (1h)
The reason: Holding Kayfun Lite upside down (mouthpiece part down) all the time, for
example when lying down.
What happens: In this position liquid does not cover grooves (1h). As a result, liquid
doesn’t flow into evaporation chamber and does not saturate wick during the draw.
What to do: Do not use Kayfun Lite in this position
The reason: Too long piece of the resistance wire is left between the screws and the wick.
What happens: The pieces of resistance wire that don’t contacts the wick get easily
overheated
What to do: Adjust the coil position to eliminate long resistance wire legs not contacting
the wick.
The reason: Resistance wire is wrapped too loose around the wick
What happens: Coils that don’t contact the wick get easily overheated
What to do: Rebuild coil correctly: resistance wire should have contact with the wick along
the length of the coil
The reason: Resistance wire is wrapped too tight around the wick
What happens: Resistance wire pinches the wick and obstructs the flow of e-liquid along
it, this can be the reason of burnt taste
What to do: Rebuild coil correctly: resistance wire should not pinch the wick
The problem: Burnt taste and flooding at the same time
The reason: Yes, this can also happen if during assembly you don’t place tails of the wick
along the grooves but leave them lifted.
This is usually done out of habit - wick tails are placed this way in some popular
cartomizers.
What happens: In this case, when you draw, liquid flows into evaporation chamber, does
not find wick tails to suck into (they are raised up), eventually rises over the air duct level
and overflows.
Meanwhile coil remains dry causing burnt taste.
What to do: Install wick correctly
The problem: The draw is too tight
The reason: Very large coil and/or wick
What happens: Air flow in evaporation chamber gets obstructed
What to do: Setup the coil and wick correctly
The reason: The blockage of the air duct (1g)
What happens: Something obstructs the airflow through the duct
What to do: Remove the obstruction
WARNING: Some flavorings that make up liquids for electronic cigarettes have a
devastating impact on the polycarbonate material transparent body part is made of.
If you use such a liquid, please use metal body part instead of polycarbonate body part in
order to avoid breakage.

I rebuilt it this morning, using more cotton as suggested. I filled from the bottom port. Everything is pumpin' well! I am OK for now. Boba's Bounty is AMAZING!!!!!!!!

Listen to EVERYTHING BEN C SAYS. about anything in life probably but especially Kayfun issues. Everyone saying that less is more with regards to cotton is screwing up some newbies with kayfuns. I completely agree. I waiting due someone to go off on me when I said more cotton... Well done Ben!

Thanks Tbev
I've got to give you my wife's number sometime so you can share this opinion with her

Is cotton the only recommended wick material to use in these?

No, and actually the manufacturer recommended wick material is silica wick.
I've tried silica and Ekowool as well, but after trying cotton, I can taste the silica and Ekowool and do not like the flavor they impart. That's just personal preference, and some people feel the complete opposite way. Additionally, the now standard 'micro-coil + cotton wick' is so cheap to make and maintain, and so easy to change out, it has become the preferred setup for many of us.

Ok, guess all I can do is try and see what I like the best. Mine's arriving today so I'll play around with it. I've watched a lot of videos on building the micro coils with cotton, so I should be able to pick that up pretty quick. It does look simpler to build than ekowool and standard coils.

if you ever feel like trying something else other then cotton, which is like the best, hemp fibers are awesome. been using the hemp for a couple months and it has replaced cotton as my #1 wicking material. it wicks better and provides a better flavor then cotton imo. it does however take some prep, like boiling and such but is well worth it. also last time I checked is only available in a kilo size which is pretty big and would last a life time, but it is really cheap.

 

[Tbev]

Yeah originally designed for silica/ecowool but as stated above evolution to cotton is the way to go, I am yet to try hemp but I have heard nothing but great things, I think that only the real ballers use hemp!
