Hahaha awww shucks. I was hoping (somehow against the laws of physics) that I would be terribly wrong.

No sir..... the laws of physics still work down here -- unbelievable as that may be.....:D
What doesn't work here is my vision. I didn't notice KFL+ with the single AFC.... duh. It's even 2 bucks less if I remember. Oh well, guess I'll just have to get used to a stiffer draw with this device or use it to experiment on my drill press....lol

Thanks for the review Horton!!

As far as your EHPro device goes… Pull the air screws out. Just curious to see if that helps with the draw. Yes it will be impossible to choke but I am curious if it'll help??

Again thank you very much!!! It is appreciated!

Having both screws out makes little difference. The screws are currently sitting on my bench. It vapes great if you like a tight draw..... Sorry -- I feel like I'm raining on the parade with my report.... Go Blue!!!

Well if you have a 2mm drill bit and a drill, here's smth that can make a significant difference.

You'll notice that at the point where the centre post threads through the positive block and kinda peeks above it, the centre post actually tapers off to a smaller center diameter.

You can use the drill bit or a Dremel to shave that tapered segment off. Makes a significant difference :)

Just gotta make sure that if you're using a drill, go slow enough. Don't want to end up mangling the center post

Thanks, Kiwi..... next time I change wicks I'll check that out. I have a numbered bit set from Harbor Freight and need to find a chart to figure which one is the right size. I also better find out what kind of bits they are... I need cobalt, right?
You know, I should just quit trying to save a buck and buy better quality. The Russians I've picked up used here and there work great. I need to be patient and wait for what I know works best for me to come along...... live and learn.....
I appreciate your advice.......

I would def recommend a cobalt bit. Cuts through SS like butter, lasts for a long time and 2mm is a ridiculously useful for performing simple mods on attys (like opening up air holes). But you could try with what you have first before making a trip to a store! I'm pretty sure either a #46 or #47 is right around 2mm.

Russians are awesome. Airflow is smooth as hell, and NEVER ever whistles. I have 4 of em. That said, the design means that it will have a similar inherent limitation in air flow, albeit probably looser than the ehpro. I keep mine fully open and like it that way.

Thanks for confirming the cobalt bit. I know I have both #46 & #47 bits so I'll see about doing the "surgery" soon -- as long as I'm sure about the composition of the bits.... for some reason titanium sticks in my mind with this set, but I don't know enough about drill bits to know if that's correct...lol. They are sort of a gold color if that helps.

Agreed about the Russians. Currently have 3 and still looking. Mine run just about full open, but it depends on the juice I have at the time. I also like being able to adjust the AFC without having to take the device off the PV.

Not raining Horton!! Its great! I love the honesty.

Beside the airflow disappointment how is the build quality?
The workmanship of the device is fine. There were no crunchy threads or poorly fitting parts. As I mentioned prior I did tear it down completely and clean thoroughly. It was very clean to start with but I just can't use something new without first cleaning it for me. Perhaps that is odd, but I like to know if there is a little germ hanging out it's because I left it there not someone else....lol. All the parts went back together easily after the cleaning. One place I've encountered problems is threading the clear tank section to the metal sections -- I had no problems with this device. The threads lined up well. Everything was fine.
I've been vaping it since late yesterday and it hasn't caused me any problems. My only gripe is the airflow and I'm going to try what Kiwi suggested to see if I can improve the flow. I don't like having to fiddle to get something to work right especially when my unsteady hands or lousy eyesight might cause a disaster. But I do not like the draw one bit and have to try something or else sell it to someone who likes a tight draw -- guess that is a thought.
Hope this is what you were looking for Gargoyle.... let me know if not..... :2c:

don't worry about the number of the bit. Find the one that fits in the hole, and use the next size up in your kit. I wouldn't use the HF bits though. their titanium nitride, (gold color) bits have a reputation of not being correctly heat treated. They tend to twist in half when put under any kind of load. And once you have a twisted off bit in your device, you're screwed!

Spend the 2-3 bucks and pick up a good cobalt at lowes or home depot. You'll need it on the NEXT Tank you buy anyway!:vapor:

Well at least I had the titanium part right....lol. The set was very reasonable and I was thinking it would be amazing if it was cobalt. I've used the bits for some different chores and they have worked fine, but never tried them with stainless that I'm aware of. I think maybe I'll pick up that one special bit from Lowes..... it's worth the price.
Thanks for the tips KnifeMaker..... I appreciate the help.....:)

call me crazy, but the draw on my brand new KFL+ v2 with dual airflow, is actually tighter than my other KFL+ v2 with the single airflow. Both Ehpro's, just purchased about a month apart. I know it doesn't make s ense, but the single airflow hole seems to noticably looser draw.

Check the air hole on the base, as well as the insides of the center post. The clones are notorious for having random pieces of plastic or metal burrings in the airflow path way

I have noticed a much tighter draw with the dual airflow and it makes no sense to me as well. I understand about the center post being the limiting factor but I at least expected the draw to be the same as a single airflow device. I thought it was just me..... It has been disassembled several times in search of the blockage and so far nada. Logic tells me there has to be something in the way. I'm going to check again when this tank is empty or I suck my lungs inside out -- whichever happens first....:D

I have this kayfun, and it is a great device. I took one of the screws on the bottom out last night to get more airflow, and it was great for a bit, but then I was having major problems with wicking. In a matter of about 30 minutes I had burned my cotton even doing primer pulls. When you cover the airholes on the side of the tank it still doesn't have enough of vacuum to pull juice to the wicks... Will have to experiment more.

It's too bad but with the control screw (s) out, it's impossible to do primer puffs... unless you have octopus hands....lol Very frustrating though. I'm really hoping I find some kind of obstruction when I disassemble next time. This is like sucking a thick milk shake through a straw......:?:
