Is this better?
Yeah, its working pretty well. First attempt at wicking is OK, no dry hits or anything, but top fill is a no-go, flooded when I tried earlier, instead I filled it like one would fill a kf4 with a bell cap.
I would be interested in seeing your wicking method, I wicked it similar to an orchid my first attempt.
Oh no its fine. I had it laying down so the JC was closed. I gave up and when I came back to try it again I had one of those "ooooh wait a minute" moments haha. Luckily I remembered before getting out the vise grips. It was tasting "off" and it turned out I burned the wick running it in DC-DC mode on my sigelei mini. Even sucked a piece of it up into the chimney.
In this configuration the RTA now works almost identically to the Aqua V2 for wicking. Wick the cotton down the entire juice channel until it touches the bottom most part of the deck. The problem i could see you running into with the Goblin is that you have that little secondary deck floor and the juice channels dont go fully down and into the bottom most part of the deck.
Goblin
SilverPlay
The SP has super big/deep channels to line with cotton which might give it a slightly better or different wicking compared to the Gob. I'll have to take some pics of another build. I use a lot of cotton (bc i use 3mm coils) so i cut it like one would a rayon build with high shoulders and then use the cotton under the shoulders to place into the channels. I've top filled without a problem. It gurgled for the first hit a tad then was absolutely perfect after.
Gotcha, yeah, that is pretty much what I did, wick down the channels, trimmed it up quite a bit, maybe next time I'll try less trimming. It didn't completely flood when I did top fill, I was able to fix it without loosing a whole tank full.
Yeah i've found that you need (at least on the SP) 2.5-3mm coils in order to fit enough cotton in there. Though who knows... i only vape max VG juice so maybe someone with high PG might get leaks and flooding even with full cotton channels?
Good about the flooding... you might be able to get it to work even better with more cotton in your buid etc. I'd be curious to see how the Goblin and SP actually fit with the KFv4 chimney screwed on... like a nice cross section view so i could get a better idea of spaces/gaps/tolerances etc.
I must say... i really have no desire to use the original KFv4 base now... nor do i want to use other Kayfun tanks on this thing! (ok maybe lil nanos when out and about) Really, really good flavor and vapor while having so many options. I wrapped a higher resistance .9ohm 3mm set of duals with 28 gauge to give me options on my VV/VW devices. Sweet spot so far.
OK, I took the time to create two identical Tobeco Keyfun V4 builds according to KickButts
https://www.youtube.com/watch?v=Jz_xVyCPEug&t=93
The coils are 5 1/2 wraps of 28 gauge Kanthal A1 on a 7/64" drill bit. As Macro coils, they
are not heat-fused together, I can see quite distinct wraps (as shown below). Each coil
works out to 1.0 ohm. The silver KF4 is running Tuscano Cigar, the black KF4 is running
Macaroon. Anybody into DIY ?
They vape nice at 10-15 watts on an adjustable. On a mechanical I was guessing the
default would be around 16 watts, as in (4.0 / 1) * 4 = 16 watts. And it is. Oh, Momma,
can this really be the end, that hot all-VG vape is SO thick! I can imagine pulling up to
a service station in 2020, and they pump Ethanol Biofuel into the tank, and you know
what the main byproduct of Biofuel is? Glycerin! Yazz sir! Fill up my vapes with sweet
sweet glycerin, Vanilla, Caramel and Banana flavored!
Everything the guy does he does for a reason. No question this is the most effective wicking I've
ever tried. The separation of the Koh Gen Doh sheet and the folding-in of the compressed outside
layer to make an inner tube is very useful. The combing out and haircut is a bit tedious but
necessary, and very effective. It creates epic capillary railroads, Martian canals, juice highways.
The way he trims, the way he lays the cotton against the deck turret, the counter-clockwise
turning while placing the inner chimney on dry cotton, all of that just plain works. Not saturating
the wick ahead of time, letting it gulp juice when you open the JC, that's perfect too. I found it's
best to loosen or remove the top nut D38 to let air in, for the juice to bubble into the wick if
you've filled the tank all the way. If you left enough air at the top it's not mandatory.
And when you're all done -- HOLY EXCREMENT!
My mod tops out at 25 watts. My next one will be a 50-65 watter, though I can't imagine
routine vaping at 50 watts. But watching THIS build decimate juice bottles at 25 watts, I
think I'd have to mount 10 ml bottles on a belt feed and water cool the atomizer chamber
to run it at 65 watts for long. It's just the thing when you need to convince the natives of
your power to invoke dark clouds AND obscure the sun with your magic !
When he says it's uncomfortably hot vaping his stock kayfun V4 this way at 60 watts, I
KNOW what he means! And not a dry hit in sight. Holy Kthulu! Thank you masked man!
Guys, watch the video, try his technique, this IS worth absorbing.
p.s. with the airflow screw B13 flush with airtube B14, I'm getting enough airflow for direct lung hits, not "panic in the Himalayas" lung hits, but lung hits nonetheless. The thing is that KickButt's wicking is so effective it takes wicking/feeding out of the equation, so you can now run the KF4 any old way you want, without being constrained. If I were an airlung freak, I'd just drill this puppy out like Swiss cheese, and it wouldn't skip a wick. I do believe this RTA rules.

Well, I was skeptical when I watched that a few days ago. Seems a lot of trouble for my 'toodle' puffing.
But if it gives me the same pleasure as some of your prose, I guess it's worth at least a try!
My wife just came in and said she was in the kitchen and there was all this smoke obscuring the streetlights, she briefly thought the house was on fire. Then she realized what it was, but came down to see if I was still breathing.
Holy, I just realized I went through another fill of both KFV4s. That's (3 ml x 2) x 2 = 12 ml in under two hours. If I didn't DIY I'd say it's Mammon'$ own wicking!
But look at the translucent quivering Martian capillary wick organ! Boy, does it wick!
Just one thing generally speaking not to do with the KF V4: confuse the many rings and unscrew the tank instead of the deck, or the Juice Control. Aye, t'was an ugly swampy mess on me jeans.

Just received a tobeco v4, i've been using a ehpro v4 for the last 6 weeks. first thing I noticed was the machining was a lot better, the threads and juice control seem a lot smoother. soaked her in warm water/liquid then in vodka. threw my standard build in and straight away got an excellent vape. only thing I modded was I put in a sub ohm kit, SV gold plated spring and tank.
im really loving the v4. i prefer the tobeco over the ehpro clone as I can now top fill, but other than that it vapes just the same.

Fernand, I may disagree with your findings .... I found no difference .... But must admit, you sir write the best prose on this forum 
We have 2 Tobeco Kayfun 4s & they have different problems. 1 will flood sometimes when refilling the other will give dry hits when chain vaped.
Hope this helps,

Hey Louis,
I got your PM but figured I'd reply here so others might benefit.
1) Flooding would occur if you don't have a good seal in your tank. I know there were a few others that have/had the same issue and I've replied to them as well. Check your o-rings. Or better yet, replace them. A visual check might not discover a nick or other defect. I would suspect the chimney o-ring (36) first. I have 2 Tobeco's and 2 other clones from FT and FC and none of them leak.
2) We need more info on your wife's build to give you better advice. I use a 2.4mm with kanthal and 3.1mm with ni200 and rayon wicks. I can chain vape and not have any dry hits on either builds. Juice can also contribute to slow wicking. Have you checked the juice channels for debris? Some have found metal shavings in there. That could also cause your issue.
I just received my genuine phoney cloney from Tobeco. I have to say it is extremely well made, well enough in fact I'm going to describe it as perfect. I was very surprised at how clean it was as well. I did of course clean it but it was spotless upon arrival with no trace of machine oil. I have to say I'm very impressed overall.
I bought it from a place called VapeOMG in Las Vegas. I ordered it on Friday night and had it in my hands on Monday. I couldn't believe it. $21.95 free shipping. I couldn't be happier.

Lookin' good Sun Valley!
Lot's of different builds 'round here.
I like (28g) 2.4mm, 11 wraps, 2.0 ohms, JOC, coil center about the height of the chimney ring, and run like 1/2 air around 9-10 watts.
The larger ID seems better with the K4 - 2.8mm seems even the most popular, even some at 3.0.
Did you download the parts list yet? You should get it. There's a link round here some where.... post it if ya find it.
Lot's of pages on this thread... post any questions/issues you have.
The Tobeco in particular seems to have been fairly trouble free...

Yes, I actually downloaded the parts list before I bought it. Thank you for the build tips. Do you build your coils touching or spaced? Thanks again.
