Best Kayfun v4 clone....or original???

[CannonE]

I recently bought a Tobecco kayfun 4 clone....immediately had to get a replacement because the threads got so locked up it couldn't be opened.

The replacement works....but seems just....I don't know...lacking.

Who makes the BEST clone of this atty? Is Tobecco as good as it gets? Or should I just suck it up and buy an original?

I'm hesitant to get the original after I bought a SM original Lite Plus and its SUCKED compared to thr EHPRO and Russian 91% clones. The clones JUST WORK but I can't get the original to consistently wick to save my life....but I can definitely get it to consistently dry hit. The clones I don't even have to think about.

What are your thoughts?

If it's not leaking and juice control functions efficiently then yes, that's probably as good as it gets. A clone that is functioning properly is on a par with the authentic.

What is lacking for you?

Seems a little "rattly" and the threads catch frequently....but the atty either leaks or dry hits. When it's leaking....even still I love the way it draws and the flavor rocks....but if I try to remedy that with more cotton, or longer cotton ends (touching the deck vs slightly above it) then it dry hits.

My Tobeco has been great, and I've not had any issues at all. However, the Infinite or HCigar might be a better clone.

They are a little finicky on the wicking. Make sure your juice control is fully open or it will definitely dry hit.

Sounds like clone problems rather than atty problems.

Is it rattly in the base and the base wobbles a bit? Strip the base and make sure #9 is properly tight. If tightening #9 makes the juice control too tight, refer to this post of mine: Kayfun v4 drifting resistance? | E-Cigarette Forum

Leaks: usual culprit is #16. Change it for an oversized one - 12 x 1.5. And check that #36 is present.

Dry hits: make sure you have a proper understanding of the juice control. Check juice flow channels carefully for burrs left by machining process.

For poor threading an idea I have seen is to apply a bit of toothpaste and work the threads a bit.

If you like the draw and the flavour, then it's worth bringing the clone up to scratch. It's very rare to see the above problems reported in the authentic.

Thanks for the help!

I guess I'll pick up a SM Kayfun 5 o ring kit and replace those.

If the leak is down to #16, then replacing with the same size won't help. An occasional problem across all clones is #16 sitting too deep in its groove. (The groove is too deep). Replacing oversized - 12 x 1.5 - tends to sort it.

Orings and more has all the sizes you need. There are multiple sets of 12x1.5mm o-rings at various prices.
O-rings

The threads are a bit rough the first time you unscrew them. Work them back and forth until they polish themselves and it will smooth out. Add a drop of juice to the threads and they will be fine. Use rubber gloves to break stuck threads or cut strips of duct tape and wrap the tape around each of the two parts you want to break loose. That gives you enough traction to hold them and twist them apart.

The #16 o-ring is a problem. The K4 comes with 11x1.5mm rings in that area. 12x1.5mm rings seal it up and stop the leaks.

I have two Kayfun V4 clones now. One Tobeco, and the other is a red o-ring clone from an unknown manufacturer.

The Tobeco has been flawless so far. The red o-ring version required a #16 o-ring to correct a slow leak and has since been working well since. It's juice control is not as smooth as the Tobeco, but I've yet to have it stick.

I always read good things about the Tobeco, and if I was in the market for another, I'd buy one again. Perhaps you just got a bad example.

I've been using an original, zero rattles, silky smooth threads, fantastic flavour!

It is a bit fussy about the wicking. But now I know how to do, it's a great vape every time.

Sounds like your clone is a poor replica, although others seem happy with theirs.

Perhaps you just got a bad one.

Considering how great the authentic is, you might consider it worth the money.

CannonE, Tobecco clone is definitely not "rattly." You might have a clone of a clone lol. If it leaks you don't have a wicking problem. If you have proper seal at the top end, it won't leak even without any wick. After a few experiments, I've settled on wick just touching the juice deck for this atty. I'm sure there' are better ways but that's what I've found works best for my juice (80% VG).

I own both the infinite clone and the original. Even though the infinite works great and provided me good means of evaluating the design before I sprung for the authentic, the fit and finish of the svoemesto are in a whole different league. Worth the price, most def. make sure you get the latest batch with the gold plated spring.

Ive got 3 Tobecos that have been pretty spot on.. When Vapor Range blew them out for $10 last month, alot of the folks that bought em when they first came out said this newer run seemed to be machined a bit better. Couldve just been that particular batch or it could be Tobeco started improving things along the way.
The only trouble Ive had with mine was caused by me taking the juice control apart and not putting it back together tightly. Part #9 can occasionally loosen up and then itll start wobbling when the juice control is closed, and it can cause it to leak into the airflow base. Other than that, theyve been perfect.

For the wicking, the KF4 seems to be one of those attys that follows the 'less is more' rule. I throw a strand of cotton yarn in a 2mm coil and cut it so it just sits on the deck like Mad Scientist does. Ill juice it up with a few drops and fan the ends out and push it back so it sticks to the positive block right over the juice holes. Seems to be the best method Ive found so far. Head over to the gigantic Kayfun 4 clone thread, tons of folks in there that can guide you to good vape.
