The gap between air hole under the coil and the coil assembly very important (Kayfun) >

[Flt Simulation]

For you folks that have been into rebuilding these kayfun / Russian style atomizers for a good while, this will be old news for you, but this info is mainly for folks new to these style atty's:

Yesterday I installed a new coil and wick in my kayfun Lite. I used the standard 9 wraps of 28 AWG wire around a 2.4mm (3/32") drill bit and used a doubled piece of cotton yarn for the wick.

This gave me a 1.6 ohm coil. I feed it 3.8 volts (9.0 watts). This has always worked well for me, and an easy coil / wick to make.

This time, the vape was not very 'heavy' and I did not get as much of that "snap, crackle and pop" sound I usually get ... But more important, the airflow was poor even with the airflow screw on my authentic kayfun Lite Plus (v2) screwed way out.

Anyway, I pulled it back apart to find that the bottom of the coil was very close to the air hole in the build deck below it.

I then removed the wick, installed the drill bit, pulled the coil upwards a little to increase the gap between the coil and the hole, and the re-wicked it again.

Everything is now back to normal!

All I am saying for our members new to building here; is that the gap between the bottom of your coil and the air hole really is important to not only the quality of the vape, but also the quality of the airflow.

Just thought this little bit of simple info may be of some help to someone new ..... School dismissed!

Ron,

BTW ... Here is about what the gap should look like below the coil (at least on my Kayfun): ..... Too small of a gap, and you will have problems!

Good class Ron, I woke up during the good part.

I can't believe I am even awake at this time in the morning ... Fell asleep way too early last night!

I've tried it at 1mm, 2mm above the deck, and the throathit is allways too harsh for me. I like it just barely above the airhole. I'm used to the draw that creates, but the flavor and vapor is intensified, and the TH is less. Different strokes and all that.

 

[crxess]

Absolutely!
Figured that one out while fiddling with the Rocket tanks to see if the Kayfun might be for me.
2 Rockets, 5 Kayfuns later.............what'cha think?

It can often be a 2 step process
1)Raise wick
2)lower Nic
No Harshness on my Kayfuns

I like it close to the air hole too, better flavor/vapor.

Lowering nic was a must for me with Kayfuns. I use 12mg in a carto in my BilletBox, but 6 or 8mg in my KFL's.

I will keep this class and discussion in mind when my R91 arrives in a few days.

Let's go one tiny step further.



I like to tweak the bottom leads into a little bit of a step. This is done by reinserting the drill bit into the coil and using the supplied screw driver from the KF (flat head side) to create a sharp angle into the lead wire. This allows you to 'set and forget' air gap between the deck and the bottom of the coil. It is also a lot more rigid than having the leads just pulled up. (As they tend to want to flatten back out with some heating and cooling / wicking etc)

I just put the flat head between the deck and the coil leads and twist.

This should give you some more resiliency over the long haul. I'm closing the gap on 2 months now on a KF coil... almost 200ml... thru it.

And this is what I do!

Asmo .... great tip !

The true best hight is resting on the base, vertical with coil center directly over the air hole, wrapped in luxurious hemp fiber, nothing better

if you like a real warm vape, but no where close to as good as the OPs set up.

On my RDAs and in my Protanks, I am a simple micro coil and organic cotton guy. I will likely stick with it.

how does it feel to transition form the dripper to the protank and vice versa?

 

[HazMatt]

Dripping gives better flavor and vapor without a doubt. However, when I am out of the house, a mini protank 2 on an eGo is how I roll. It is hard to beat that combo for size efficiency and with my own rebuilt coils, I am satisfied with the quality of the vape.

I am more of a dabbler in RDAs. I drip my favorite e-liquids as a treat at the end of the day. And to try new e-liquids of course. I like single coil builds over duals or quads. I wish I could find a smaller 2 post RDA with adjustable airflow that has good build quality and is made of stainless steel. Unlike those SmokTech RDAs with brass posts.

I can't use protanks anymore. Idk how you do it. Even after rebuilding them down to 1.2ohm and getting them wicking perfect they still suck balls compared to a KF.

I put a nano kit on the KF. Got small mods and called it a day.


I just swapped the 3.1 for a 91% and now it's even smaller with the nano kit.

I mean if it works for you... I'm just done with all OTC atomizers... Period.

On the contrary, cooler, richer vape, and hemp runs rings around cotton for wicking & durability

I just wrapped my KFL+ yesterday, and am finding that I like the coils almost touching the deck for the best vape. Keeps it nice and warm!

My very first Kayfun ( actually a R91%) is on it's way from Washington state. This is my most anticipated vape mail yet.

That is a nice compact setup you have there.

Here is a pic of my mini protank 2 on a 400mAh vision micro ego. Between a 10ml bottle from Juice Mafia and a 15ml bottle from Flavorz by Joe

I'm running a twisted 32G micro coil in mine now. I upped the resistance to 1.5 ohms and run it with a kick at full power.

Try it. Very very happy with it. I thought I loved my 28G micros... Which I usually run @ 1.1-1.2 ohm's sometimes with or without a kick.

I like the cooler vape. Better flavor.
