Attack of the (Kayfun v4) Clones!

[Steamer861]

I guess it would
You just invented some thing new Vapours Say Estimated VPML

Wouldn't that be VPML (vape per milliliter)

On my KF4's I get the same VPML as my kayfun lites.

So has anyone figured why these things seem to suck through juice like a Hemi though a gallon of gas??? I can blow through two tanks in no time. Not running any kind of crazy high build or high power either.

I have found attys with small chambers and tanks do that. "Boil" off after use even though you cant see the vapor. Some of the heat is transferred to the chamber and the juice and the atty. Even a couple degrees makes a difference. Chain vape for a while get her good and warm then sit her down and come back. You'll see the level is lower just from sitting there.

I have actually noticed that. I come back thinking I still had a smidge of juice in the tank and there is nothing. I dunno. It just seems like I am running through juice much faster with my Kv4 than I do with my Lemo and KFL's. I know the capacity is a little smaller. But I am talking a major difference in the amount I go through. Oh well as it was said. Nature of the beast,

Yep, less juice, less glass, less heat dissipation.

Oddly, just the opposite of a big bore hemi. LOL.

 

[k2zs]

Correct. But only once actually. That was the way I did in my lite plus.

The other 10+ builds have been with the chimney on and stuffing lightly. (I cut before placing the chimney on though.)

For the record it has nothing to do with how hard I pull when vaping because I can primer pull til blue in the face and still won't bubble.

Sorry for delayed responses visiting someone in hospital (long day).

Thanks for all the help!

I'm sorry, and I don't mean to offend, but if you can pull that much and not get bubbles then you must have the juice turned off...

You're sure that you are screwing the juice control in the same direction as you do to screw the atty's 510 on to the device, right?

 

[Garemlin]

Ok without having to read back thorough eleventybillion posts. What was the fix for oh fluctuation??? My Provari just started reasding my Kv4 at 6.8Ω then down to 5.4Ω. Took it off put it back on and it reads at 2.8Ω. It is a 2.0Ω build.

Might be something with the spring???

I rarely get bubbles, unlike my KFLs.. My v4 is still working just fine..

Yeah that sounds like a spring thing, except for all you did was take it off and reinstall it then the ohms dropped. Very interesting indeed. Did your 510 pin maybe get turned in a little and cause an erratic connection?

I have messed around with a few builds by putting them on my ohm reader and then opening and closing the juice control valve to see if there is much in terms of resistance fluctuations. My tobaccos spring is silver plated copper and really didn't see much fluctuation. I guess that is why it seems to work pretty well on my DNA40s. I am interested in what you find out.

On mine when I got the resistance jumping it was the counter screw, once I rebuilt the deck it was fine.

Do you have any wobble in you JC?

No wobble in the JC. But I am getting more random occurrences of flooding and leaking after I fill. it isn't every time. I did an o-ring check the last time I rebuilt it and everything looked fine. And I think I am getting a little seeping out of the 510 pin. I have noticed juice on the bottom when I take it off. But it isn't anywhere on the sides. This thing is serious high maintenance. Never had a single issue with any of my KFL's or Lemos. Build, fill, vape, repeat.

Got my tobeco spare parts kit today from vaportek. Looks good, but didn't come with a spring, that was a little disappointing, other than that I'm satisfied. Although it would have been nice if tobeco had just included the spare parts to begin with, but whatever.

I decided to drill out the center post on the tobeco now that I have a spare on hand. Drilled it out to 7/64th, which I believe is slightly larger than the 4S kit. I do notice it being slightly more open now, seems like I can do a restrictive lung hit a bit better now.

I'm happy with the results, I may dremel out the bottom a bit tomorrow to see if that opens it up a bit more.


Oh, and I wicked it with a little JOC, and it seems to be wicking fine with 20/80vg. I probably use less than most it sounds like, just enough to have tension through the coil, and sitting just barely on the deck, fluffed up and fanned out.

I also received my Tobeco spares today and was just going to comment about the spring not being included, not that it's suppose to be but one would kind of expect it to be included.

I said before that is not it. I know how to work the juice control properly. I think I spoke incorrectly there and called what I do "primer pulls", but really I didn't mean pulling till blue in the face with the air holes covered (that Def works), but I usually try to just pull hard without firing as a sort of "prime" if that makes sense.

I also found this thread on the subject (with an older kayfun) and is giving me more info: http://www.e-cigarette-forum.com/fo...fun-lite-plus-dry-hit-burnt-taste-issues.html

But honestly this thread has been more than helpful. It's either my cotton, which is my homework to build again for the 15th or so time, and/or to try some other juices.

It's *not my juice control being off, and it's not my vaping style.

I do need to step away from the thread, because I'm frankly cluttering it up at the moment. Know what I mean?

I'll get to my homework and will report back anything good, bad or indifferent. (Again folks have been more than helpful and have run through every possible cause/etc).

*For the record, I'm not a complete id*ot though. Lol

Oh and I also had some glorious vaping off this unit today. Glorious! And the only reason it was glorious is because it was actually wicking very well on the last 1/4 or 1/8 of the tank when almost gone. Seriously I was like "oh yeah - this juice is damn good - I forgot how good it is!". Nice flavorful thick moist vapes.

**Then I refilled like 1/2 a tank and went "oh yeah - back to dry hits and not good taste."

Yep, I was kind of expecting one, guess I didn't look closely, not a big deal, but would have been nice.

Probably cause that's the only spare part the tank actually comes with.


Man my #1 has loosened itself up somewhere.. Outta nowhere on my lunch break the damn things leaking from the JC, and the gap is back. Not bad but its definitely seeping in there. Gotta tear it apart again tonight!

From the sound of things #9 has probably come loose.

Alright folks - evening check in. ***Good news*** (I hope).

Everything seems to be working nicely now. And I think the culprit was me using too much (too thick) of Japanese cotton. This time I ripped off the outer layers of the pad and fluffed really good before tucking down in gently. I cut it around 22mm or around the width of the unit itself.

Sorry some of these pics are in portrait... It was tough taking the shots with wet and oily fingers while holding my Phablet... Haha. But looking at these pics of my latest "trouble build" it was abundantly clear to me that I had way to much (wide/dense) cotton in there.

The last pic you can see a shot of my fresh wick, looking good. When I filled it up (no leaks in the Tobeco mind you) and turned the juice back on, I got some nice satisfying bubbles!! Then my first 5 pulls I watched and saw more bubbles each time and good flavor staying.

Hopefully this helps someone else in the future. I'll report back if it's too good to be true, but this was a nice full top off and no issues right off the bat - which is extremely promising! Now I hope I can get the ehpro black version working and to stop leaking on fills... If not - I have another tobeco anyway (Yes I went all in on the v4 Clones... Haha. Glad it seems I'm solving my little mystery).

Ya live, ya learn, you get better. Thanks VERY MUCH for the help from this forum!

Oh and finally - I moved the coil up just a tad as well.

 

[Hammy75]

I have a FT B version and 2 Tobecos (SS and Black). I use a tighter draw for mouth to lung hits. I would say it's equal to an EHPro KFL+ almost wide open but with the screw still in. I find it gets gurgly or slurpy...not really sure how to describ it. It doesn't leak out the air holes just sounds kind of weasy(fairly annoying). I am trying to figure out if it's leaking. I find it hard to believe both the Tobecos are leaking and I am relatively sure that the FT is. I replaced #16 o-ring with a new buna N70 11x1.5 but still gets a decent amount of juice down to the air holes. I would try the size up like dwcraig has but it's $10 shipping to Canada from the o-ring store so not really interested in dumping any more cash and 2 more weeks of waiting into it.

So anybody have a similar air flow setting experiencing this? It's not that bad but does bug me so I figured I would see if I am alone on this. Apart from that they have been vaping well but I was hoping for less noise then my KFLs.

On another note this thread has been very helpful so that's to all who have participated.

Edit: I have tried a couple different builds. Most on a 2.4 micro coil 28 Kanthal 8 wraps 1.4ohms Shiseido cotton touching the deck firm but not jammed in the coil.
