Kayfun V4 problems

[Jsav27]

Hey Guys,

Just had a few questions. So i have jsut started building about a week or two ago. I have the Kayfun V4 on a hana V3 DNA 40. When I first received the kayfun, i throw a coil in it and wicked it with some five pawns castle long reserve. Everything was perfect. It was at about 1.8 ohms, and I was vaping at about 18 watts.

After that first build i have had nothing but problems. I realize i am new to this, so this past week i have built about 50 plus coils with all different size wicks. I am using KGD cotton. For some reason I continue to get dry hits after the dripped liquid has been vaped. I realize the first error I was doing was putting the coil like on the air hole. I did correct this and had luck for a day. I refilled the tank with different liquid, and rewicked it. Again back to the dry hits. Havent been able to correct what i am doing wrong. I do realize that after i make a coil with the juice flow wide opened, and put the tank back together, then add liquid with the juice flow turn off, that when i turn the juice flow back on most of the time i dont see those air bubbles come up.... which seems odd to me.

Last night i used my 28gauge kanthal A1 wire, about 8.5 wraps which read about 1.52 ohms. I heated it up and put it on the Hana which read it at 1.44 ohms. I dripped liquid on the cotton and coil. I did cut the wick a bit shorted then normal hoping the liquid would flow up easier. I was wrong. After vaping on it for a few minutes, it went dry. I took it apart and the wick wasnt wet at all. I beleive this could have been possible due to the wick being a little shorter.

Can anyone give me advice? I have watched many videos and this and for some reason i cant seem to get the juice to come up. I have been using my Atlantis with the CF battery. I just thought that going with a variable wattage box mod with a rebuildable would allow me to build any kind of coil i wanted and change the wattage to experiment... I didnt realize i would need everything exact or it wouldnt work at all..... Any tips or suggestions would be great! I would send a pic but im at work, i can latter though.

Thanks.

Its not the coils, its the wicking. Its either blocking the juice holes or too short to touch thm.

You want the wick tails just lightly touching the deck. If they are touching, and it still does this, just take a mini screwdriver and push them back a bit, reprime, and it will be fine. I've had to do this a couple times myself. And once it seemed my tails were just a tad short. I took the screwdriver, and sort of pulled strands down gently, and that solved it.

I always have beginner's luck with new attys, too. Then several weeks later, mess up a wick

Well, that juice is 50/50 blend, so it shouldn't be too thick.

You could try to take dry puffs before you actually vape. I've never used the kayfun, but the dry pulls work well with the subtank mini if I do it to make sure the cotton is saturated. Just a quick thought.

Maybe you have too much cotton, there shouldn't be a ton of resistance when you pull the cotton through the coil.

Hopefully a few of the guys that use the kayfun will be in shortly.

Well, if its a clone, make sure all the holes are drilled properly, many reports of barely or partially drilled holes.

Always make sure to leave a small space or bubble after filling, overfilling can cause vacuum lock.

Is the juice control wide open? I know nothing of the kayfun 4's but watched the reviews. make sure the juice control ring is turned counter clockwise to open up the juice.

Check out this post and scroll down to the pictures labelled "juice control". You want the base plate to be down on the threads when vaping, not up and blocking the juice ports. When you have the coil assembly out, loosen the contact screw on the bottom of the coil assembly and adjust the juice control ring counter-clockwise as viewed from the bottom of the coil assembly to open up juice flow. The pictures should give you some insight on how it all works together.

If the wicks are touching the deck and not blocking the juice holes, the problem is likely the juice control not being backed off fully. It's more of an on-off assembly than it is a variable juice control. It's either open enough to feed the wick or it's not. In between will just cause problems. If you don't loosen the bottom contact screw in the 510 threaded connection, you probably won't be able to turn it enough to fully open and close the juice control.

Another thing that will cause dry hits is filling the tank too full. You have to leave enough room in the tank for a good sized air bubble or it can't feed juice. The bubble gives the tank some "stretch room" to allow the juice to exit through the air holes when you vape. A completely full tank will air lock and you won't get juice to the coil without blocking the air holes and sucking a vacuum on the drip tip.

There are literally dozens of how to video's here on this forum and on YouTube, I suggest watching as many as it takes to figure out the problem.

Or try a local vapor shop with experience.

Very hard to diagnose a problem not being present to look and experience it for yourself.

Good luck to you, I love my Kayfun V4

I was getting dry hits on my Kayfun V4 when I first got it. As its been said, wicking.....they need to perfect length to hang down and hit the juice holes. Also when rewicking I clean out the holes.

I recommend drilling out the air hole and removing the screw at the bottom. Works wonders

My current build on my kayfun is 3 wraps dual coil in .8 ribbon (I think). Running at 18 watts and coil reads .5 Ohm.

Great taste and nice cloud production.

Some good suggestions above.

Also:

Try a 3mm coil.
And are you continuing to try to vape at 18w? If so, drop the watts to ten and see if that helps.

Wow, thank you guys for the responds time and all the info! I really appreciate it. Looks like i have some work cut out for me when i get home to check a lot of stuff. It is a authentic Kayfun 4. I made this wick a bit shorter then normal becuase before when i was getting dry hits i would take it apart and the bottom of the wick was really wet but it seemed like it wasnt wet underneath the actualy coil. Last night after i rebuilt the coil and rewicked it i didnt fill the tank full because i didnt want to waste the looper juice, so i only filled it half way.

I have watched many reviews on how to build this, but i will continue too. I have adjusted the watts down normally when i start tasting burnt. Most of the time I will build the coil, wet it, then vape. After a few puffs my longer pulls start the dry hits. Ill take some pics and post them later on after i try a few things. Thank you guys so much for the help, and i will continue to take more advice and options to try. If i am holding the 510 connector, and turn the airholes clockwise it should open it up, and counterclock to shut it... I beleive that is the correct way as far as what i have read in the book.

I agree that 18W may contribute to the dry hit problem. The K4 isn't designed to feed juice fast enough to keep up. A dripper might be the solution.

I can vape all day on the K4 at 10W without dry hits. If I take it to 15W I will eventually get dry hits. You can boost the juice feed by wrapping a finger around the base and covering three of the air holes while using your thumb to cover the 4th hole. That lets you apply suction to the drip tip to feed juice to the wick and restore the vape for a while.

The solution may just be to drop the wattage to a point where the K4 can keep up and wet the wick as fast as juice is used. That's assuming the juice feed is wide open and allowing the juice to leave the tank and saturate the wick.

Best thing is to watch Todd's review and watch how he wicks it. He keeps juice control wide open at all times

Assuming you are holding the atty upright then this is correct.

Another thought: KGD has light padding over fluffy cotton, right? Some report enhanced wicking by removing these outer layers.

Play with your deck while its off the tank so you can see what it looks like fully open (juice control), all the way down. And how it looks as you begin closing it, moves up.

First thing to check if you're dry hitting. Unscrew the deck from the tank and see if its fully open (all the way down).

I'm only running about 14.2W with a 1.3 ohm coil. The juice holes are smallish. It can't feed as quickly as some tanks. I'm using a 70vg juice. Maybe I could get a little more power with a higher pg juice.

 

[Jsav27]

DaveP,
I cant reply to your eaarlier post so im jsut going to do it this way. About the 510 connector.

I did take it at when i cleaned everything, i did tighten it a bit tighter then it was because i notice a tiny bit of juice down there. Do you guys know if its possible that i could have over tighten it and that is causing me to not be able to open the juice all the way? I was jsut a bit confused on that part. I do have the airflow screw all the way opened underneath it. I didnt know if thats what you might have been saying. i think i need to loosen the screw. Thanks for all the help guys, my mind is racing with ideas i can try now thanks to you all.

I have taken it all apart to see how the juice control actually works. Because the first time i took the deck off to fiddle with it i just put a full tank of juice in there... but i didnt flip the tank upside down, so basically with in a few minutes the tank drained out. So i figured i should take it apart and really understand how that juice control works.

 

[Jsav27]

i keep lowering the wattage also to try and help with the dry hits. Last ngiht after i built the 1.44 ohms coil, i dropped the wattage to 15. Then when i noticed the dry hits i lowered it even more.

I played with mine a few times to get the hang of it . Being a new, innovative feature, I wanted to get comfortable with it.

That will also tell you if the 510 pin is preventing it from opening and closing. I know some of the clones had that issue, but not sure on the authentics.

Yea when i get home i will loosen it and rewick with a little longer wick. the first time i used it i just throw a coil and wick and it did great... i really think i need to loosen it a bit. do you even notice a tiny bit of juice on near the 510 pin and on the mod? thats why i decided ti tighten it more... i guess that was a wrong idea

 

[Jsav27]

Alright guys update time. Looked at the wick and it seems pretty good to me. So i left that alone. took the bottom base apart. check my airflow screw which seemed to far out to me. So i re screwed it all the way in and then start the unscrewing. I noticed that i could go past the maximum airflow and it allowed me to unscrew it all the way. So i reversed went tight and unscrewed until i couldn't notice any more air change. I then screwed in the 510 pin. After that i noticed that the platform wasnt all the way down as it should be when fully opened. Basically i had to use more force then i thought i would to turn it so that the platform was all the way down. Then i reassembled, added a bit of juice to the coil and wick, put tank on and it has been vaping great since without any dry hits!!! Thank you all for letting me pick your brains and giving me all the advice! im so excited to finally be able to really experiment with this setup without having all the builds hitting dry!
Thanks all!!
