EHpro Kayfun 3.1 and kayfun clones: has anyone taken a drill to their kayfun? V. Im having wicking problems

[betterthanyou]

I've had an ehpro kayfun 3.1 for 5 months or so now. I use single kanthal microcoil builds with cotton.

I can make great wicks that wick great for a few days, at most, before burnt hits start kicking in and I need to replace it. Sometimes I only get a single day out of a cotton wick. I have my airflow screw backed all the way out and removed.

I feel like the problem is the channels (grooves) that run along the center piece for whatever reason are not getting juice to the coil and wick quickly enough/properly. Anyone else had this problem? Has anyone widened the channels on a kayfun by drilling them out?

I would expect the kayfun to continue wetting the wick every time i fire and take a drag. For some reason this isn't happening as a process.

Any ideas?

And to get juice to the wick (as a way of 'priming it'), do you cover the hole where the airflow screw is and inhale through the top of the kayfun?

In that case, you may not be generating enough vacuum in the fire chamber to pull juice up to the bottom of the deck where your wicking can pick it up. As a test, put the screw back in to restrict the airflow some and see if that doesn't help.

Correct. If you plug the air intake completely and apply some suction, you're definitely going to pull juice up those channels.

This is good advice. If only I didn't lose the .......n airflow control screw after I pulled it

With a proper wick/coil setup, when I plug the air intake completely and apply suction, is there any small sound or sensation I could identify to know that the juice is getting sucked up into the channels and into the wick?

I'm thinking about picking up a second kayfun clone. Like I said I currently have the ehpro. Should I go with tobeco, hcigar, russian 91?
Or should I try an aqua clone? Keep in mind for the time being I still intend on using single microcoils. Aqua seems to be best designed for multiple coils which I would obviously want to use on a mech but for the time being it will be used on a regulated mod. But figured I might as well ask if I may have a different vaping experience using single microcoils in an aqua clone.

I don't have an Aqua, but my understanding is that they're more difficult to get running right than a Kayfun is, so I doubt it would be good advice to try one of those. I have an R91 and a real KFL+v2. I don't have any experience with any of the more generic clones, but of your list, I'd say get an R91. But even before then, I'd try to get what you have working, so:

If you lost the airflow screw, put a piece of tape over the air intake as an experiment. A small bit of masking tape or electrical tape will work fine. You don't want to cover the entire hole. Place the bit of tape so that one edge partially covers the hole. You can control the airflow based on how much of the hole the bit of tape covers.

Oh, and the other thing that might be worth asking you is: What kind of juice are you using? If it's a really thick (viscous) mostly PG juice, you might try adding a few drops of distilled water. This will thin it and allow it to wick better. I do that with Boba's in my KFL+. It doesn't take much water at all.

Be sure and experiment some more with the size of your wick, both in thickness and length. I have the ft clone that comes in the tobeco box. I doubt that it's a tobeco, but anyway, it has the narrow channels plus they're real shallow where the two channels come together. I just knew I would have to drill the channels but decided to try it first. It worked great for my vaping style (more below). I've since picked up the cheaper clone with the logo. The channels on it are well defined and look much better on it. However, on my first build, I had some flooding issues. I had to drain it and rebuild with longer tails on the wicks. It works great for me now as well.

Caveat though. I have a habit of turning my rig upside down and back up again every 3 or 4 puffs. Keeps the wicks well saturated like dripping or squonking. Would they give dry hits without that? I don't think so, but I don't really know lol.

But tilt or not, a lot of the posts I read manage to solve their wicking problems by finding a build that works for them, regardless of air hole size.

I just spotted some pictures that may help. If you look at how short the wicks are in the first pic, that wouldn't work for me but several do cut them that short, wet them and tuck them against the sides and it works for them.

I usually put the bottom section of the chimney on with the wick ends poking out the top, trim them about a quarter of inch above, wet them and poke them back down the sides. I take a small screwdriver and rake them away from the top of the channels. My point is to experiment to see what works for you. http://www.e-cigarette-forum.com/fo...ian-91-coil-reccomendations.html#post12620921

Here's a good video as well. Hope this helps. kayfun lite coil set-ups - YouTube

Try using a bigger coil and correspondingly bigger wick. I run high VG e-liquid with cotton wicks... and ran into problems with 1/16 ID microcoils.

Tried 5/64 and it was better, works good with mixes up to 80% VG but has trouble wicking anything higher.

3/32 ID is the best yet. No dry hits even with 100% VG (which is super thick and viscous). Runs any other mixes fine too.

I've recently got a clone that had tiny juice channels. I reamed them out and it works fine now. You need more of a dremel tool or at least a bit to spin in a drill.

I make my coils around the tiny screw driver that comes with the kayfun clone.

I cover the juice channels with loose cotton. That way it doesn't leak. All four I have laying in front of me work 100% like that. Some weird condition in my backpack can make them leak but they don't in my pocket or laying on my table.

Pictures are a good way to solve problems.

I currently have the Kayfun v3.1 clone from EhPro. I haven't had the exact problems you're describing but I have had issues with vapor production and in turn, flavor. I was actually re wicking my rig for a drastic juice change and actually damaged my coil in the process, forcing me to rebuild the coil all together. Initially, it was working great before I jacked it all up. The problem was after rebuilding an exact replica of my previous set up, it would not vape. ( I take pics of all my builds and label them for reference because I'm insane) that being said, I started to wonder why the hell is this thing acting different after I built the same coil and everything? What did I do different? I soon realized that I was trying to wick this thing the same way I wick my droppers; stuff it like a pillow! I pulled the cotton wick out of my micro coil and segregated it down to about 1/4 of its original size in thickness. I put on the chimney cylinder with the wicks standing up and then cut them down to about 1/8" above the cylinder. I put them straight down into the cylinder, saturate them and kind of rake them over against the side of the terminal riser. The ends of my wicks just barely make contact with the base where the juice comes up the channel. I reassembled and filled as usual and fired that thing up. Boy was I wrong. It did not work great on the last build, it works great NOW! When wicking a kayfun, especially with cotton and micro coils, LESS IS MORE! I'm not too concerned with huge clouds when running my kayfun, more of a flavor and ease of use kind of set up, but this thing is still like a mini fog machine. I've re wicked it 4x on this coil ands it is still working exceptionally. I may never rebuild this thing! Lol Give less wick a try. You won't be disappointed.
Bottom line: (literally) When wicking a Kayfun, less is more!

When you cover the airhole and apply suction, you should see small air bubbles float up inside the tank - this shows that juice is going where it should, along the juices channels.

When I buy a new Kayfun, first I'll do my regular 2mm coil build and see how that goes. If it's below par, I'll take out the screw (as you have done) or drill out the airhole a little (if it doesn't have airflow adjustment). Finally I take the dremmel to the juice channels as a final resort. But out of over 20 Kayfun type attys, I've only drilled out the juice channels on two attys.

As others have said, tweek the coils and wick first. I've moved on to Rayon now for all my wicks, for me this is the next step in wicking material
