Guys I'm using rayon. It's wicking great at 20 watts. But when I put my kayfun on the side for more than 5 mins, first hit is dry and scratchy is there any reason for that?

Most likely the tank is not full and when on its side, the one channel is facing up. In this position the pressure inside chamber gets messed up slightly and then takes a vape or two to balance again.

It's not on its side, it's sitting straight. I was just wondering if it's normal. Getting it to wick at 20 watts is great to begin with.


So you mean 'When you set it aside'? Not 'On its side'?

I've gotten a bad taste from mine when sooty juice has drained back into the tank from the juice deck, but that's only happened with NET liquids.

Have you noticed the juice changing color in the tank?
Do you have the air flow control set for a tight draw?
Are there spaces between the turns of your coil?
How much distance between the coil and the air hole?

Nope, the juice doesnt change color in the tank.
The airflow is set to a medium draw more to the "airy" side.
Nope, the coil is glowing from the inside out and it's pretty solid
Not a lot, I found out that when raising my coil the vape gets really warm which I dislike.


I have tried everything, I have washed it and rebuild it but the problem remains... The vape is awesome but after half a tank it doesnt taste at all like the first puff, the flavor has changed. It isnt an awful taste but it isnt what it used to be, like its muted.

Is your coil gunking up?

Sorry I misunderstood. No it really shouldn't do that and the first thing that comes to mind is a thin wick tail or a tail placement that is out of the sweet spot. Any specifics?

Guys I need some help... After setting a new microcoil (30gauge, 2mm screwdriver, 1,3ohms) I get a really good vape for about half a tank and then the vape gets really bad... Not burn or dry hits, it's like the cotton needs to be replaced.
What am I doing wrong here?
At the point of muted flavor, have you opened up the kayfun and inspected it? Is coil and cotton look normal?

Yeah... I have this problem for over 2 weeks now. Yesterday I fully disassembled it, cleaned everything and put it back together... I even changed the insulator (I had the same one for over 6 months and I thought i could be it). Coil is looking fine, my eliquids are very "light", they dont gunk up the coils...

About the cotton... I put a small piece so it can pass freely through the coil but no so much that I can take it out of the coil... I trim it and put it on the side wall. After that I put back my chimney, check for hot spots and fill it up. It's an awesome vape for the first 1-2mls but then the flavor is not the same.
Again, no dry hits, no burnt taste, no problem with wicking whatsoever.

So when it started to taste muted and then you took it apart and looked at everything, there wasn't really no tell tail signs of anything wrong? Let me ask you this, let's say you vaped a tank or even a half tank then you wanted to change out wick, how easily at this point does it come out? When inserting, yes it kind of needs some resistance but not overly stuffed but once it's saturated and vaped, it should come out alot harder then of the pull resistance when dry. I would say your issue can be a wick that is not quite dense enough and after a while it's slightly degrading and possibly looses full contact with coil. Maybe try to twist the wick or kind of roll it up some, then insert with the same thought in mind that you had before. This slight denser wick may hold up better. Also did I read this right? You said you insert wick in the coil then check for hotspots? Explain this? The only time one checks for hotspots is before wick is installed.

When I noticed the difference in the flavor, I checked my setup and removed the cotton with my tweezers but there wasnt much resistance, but this is how I always set it up. The middle of the cotton (which is inside the coil) was not burnt at all, it had a small discoloration.
I can't put a lot of cotton inside the wick because I am using a 2mm screwdriver (like a 5/64 drill bit) to make my coil and it's really thin when I pass it through.
I have lost my scissors so I have to trim my cotton with nailclippers or by hand.
Do you think I should make a bigger coil for more cotton? Like 3/32 perhaps?

Yeah, I made a mistaked about the "checking for hotspots" thing. I meant that when when I put back the chimney I prime the cotton and give it a test fire. That was what I meant :p
Also recently after leaving the mod down for like 5 minutes I hear a little "pop" when I fire it and a small amount of eliquid comes through the drip tip. What is causing this?

PS. Sorry for butchering the English language!

I completely agree with you. If you consider the length of time they've had to design, engineer and test their new model I'd be willing to bet it'll be a game changer...just like the original was.

Have you heard any possible information pertaining to the device ie anything lol

Thank you, worked like a charm! I had some flooding but I turned it upside down, blew through the drip tip with some paper towel near the air hole and the excess came out.



I have a quartz tank kit on and I can't fill it from the bottom, it floods through the drip tip :(


Also, lately I get a very warm vape with every build I make... I do raise the coil but only a bit so it doesnt touch the air hole. What can I do to make it a cool vape again? :(
Build a higher resistance coil.... Or open up your airflow more, or wick more efficiently, or use a thinner juice if your e liquid is predominantly vg based. Hope that helps, good luck, may the Vape be with you =]

You can name at least 10 atomizers with a tweak here or there. Since they didn't match the original, I'm afraid an updated kayfun will also be left behind.
I think a quartz tank would be a great addition. Higher temperature resistant insulators so you could build to lower resistances without the risk of melting them, a wider range of airflow so you could do mouth to lung hits, and maybe some more aesthetic options like brass or copper versions. With copper though the interior would have to be stainless to avoid the issues with copper leeching

This is my build after half a tank, this is where I sense a difference in the taste.
Am I using too much cotton?

it does look like the tails maybe expanding after some time which then might be slightly blocking juice channels. I think your fine with the 2mm diameter and it looks like your amounts in the coil looks good but the tails may be just a little to much. I know you said you lost your scissors but next try threading through then slightly trimming tails or maybe just don't run as far down. cotton expands as you know and like I said it maybe possible they are expanding just a bit to far thus blocking off the flow of juice. you also said the coil has been in for 6 weeks? is this the one in right now or did you change it? usually coils really don't go bad but when things go wrong it may be worth putting a new one in anyways just as a process of elimination. I have heard of micro shorts in a coil that may be undetectable by eye but can cause slight burning on the wick. I haven't personally ever had an issue with micro shorts but at least if you install a new one, you know its not the coil for sure. is it the pic or is that one tail darker then the other side?

It's also possible that you don't have enough cotton in the coil. These things are tricky to know exactly what's up but when you said something about popping, that makes me think of improper wick contact. Do you ever notice an after burn? This is a slight sizzle sound that is produced from vaporized juice and is common but if there is not enough cotton in the coil, this sizzle continues well after the fire button is released. This is usually the sign of to little cotton just inside the coil. I'm just trying to figure what can change after half a tank of juice and it seems like something to do with the wick.

Well I rewicked. It seems going fine now. Reduced density at the shoulders a bit. We will see. Thanks.

It did look like quite a bit down on the lower deck. Personally I do like a good amount down there but whenever I rewick, I notice that between the cotton and channel slot, that there is a slight gap. As for cotton amounts in coil, when I rewick and pull the old one out it has a good bit of resistance as it doesn't just easily slide out. I mean it's not so tight that it moves the coil, or that I have to cut the tails to remove, but it definitely doesn't just pull out super easy. I try to obtain the most amount of cotton in coil without it being so tight it prevents juice flow. Good luck

so, there's this: SLVRBCK Designs

havent tried it.

I received the centerpin today and so far I cannot recommend it. Suspicions are correct -- you cannot torque the pin down enough to avoid the deck from rotating. I mean, it's completely loose. Since placing my order, the manufacturer added a recommendation to cut off a piece of insulator and jam it between the negative post and the positive block. Whatever. I will not be doing this anytime soon. And from playing around with it, it's very easy to cross-thread, which I obviously want to avoid.

This would have been awesome if the threaded section were not sliced up. Or he should have included a piece of delrin or peek if jamming up the blocks is the only way to make this design work.

So, this highflow center pin is not a direct, easy alternative to the stock centerpin as I had hoped. it requires a hack to fix a design flaw and I cant respect that enough to bother. I'd rather not increase the risk of a short or my kayfun becoming disabled away from home.

Thumbs down.
