I’ve tried many atomizers during my time vaping, but I always end up going back to the Kayfun. I’m not exactly sure what it is about it is about them, but they just suit my preferred vaping style perfectly.

One thing I never really liked about most other atties out there is that mine never really looks much different than someone else’s. Sure, you can usually swap out the drip tip, and you can generally get a given atty in a choice of colors, but nothing on the market compares to the Kayfun as far as customization goes.

I’ll be focusing specifically on the Kayfun Lite Plus V2 in this article, but most of the parts listed can also be used on related atomizers such as the Kayfun 3.1, Lite, Lite Plus, Russian, Russian 91% and quite a few others.

Here is an image of a Kayfun Lite Plus V2, mostly disassembled and labeled:

Every single part of a Kayfun can be swapped out in order to suit your preference, as I will show you.

Top Caps

There are a wide variety of alternative top caps out there, from manufacturers such as Science of Vaping or Steam Tuners. There are also many top caps sold on Fasttech, one even offering the ability to top-fill your Kayfun. Avid Vaper also offers a top filling cap here. My personal favorites are the Science of Vaping Micro Dual (Left) and the Steam Tuners Fortune, designed to match Fortune Mods devices (Right):

Science of Vaping “Micro” Dual Steam Tuners Fortune

The Micro Dual offers the option to ditch the chimney section of your Kayfun altogether, for an extremely tiny and impractical setup (as shown). The Steam Tuners Fortune cap has a similar design, but has a built-in drip tip for simplicity’s sake. An alternative to the Fortune cap is the Avid Vaper Drop Cap, which ships from the USA, and is priced slightly lower.

Many aftermarket top caps offer an increased liquid capacity, so while they may be shorter in height than the stock cap, they are ‘scooped out’ to the point where inverting your atomizer makes your tank look empty! For example, the Science of Vaping Reservoir Mid Cap can hold 1.5-2ml of liquid on its own.

Tanks

The stock Kayfun Lite comes with a 3 part tank. The top and bottom stainless steel sections are interchangeable, and the middle section comes in both stainless steel and polycarbonate. There are quite a few alternative options here, starting simply with alternative middle sections in various colors.

With these, all you’d need to do is swap out the middle section that comes with your tank.

Another option is a full polycarbonate tank. Pictured below is a Kayfun with a long mode poly tank:

These polycarbonate tanks come in a variety of lengths, finishes, and colors. My personal favorite is the (now sadly discontinued) full size polycarbonate tank in a frosted finish. I like the full polycarbonate tank setup because you can always see exactly how much liquid is in your tank without the need to tip it.

This rather unusual piece replaces just the top and/or bottom sections with polycarbonate, which can result in a unique, genesis atomizer type look. The parts are meant for an Orchid, but do also fit Kayfuns.

Both Science of Vaping and Steam Tuners offer quartz kits, for those who just don’t like the idea of plastic touching their liquid. These are also available on Fasttech, but having personally ordered and tried a couple different SKUs, I can’t personally recommend them. One issue I’ve found with some quartz kits is that your tank is basically just held together with o-rings. Science of Vaping has solved this problem by making the chimney connect to the top cap with threads, not just an o-ring:

This design unfortunately necessitates a specific top cap, but they do offer a few choices in various sizes and shapes.

Lastly, the bell cap (and variants):

The bell cap replaces the tank and top cap with one piece. While not very practical due to the lower capacity and increased fiddlyness of keeping a proper seal to avoid leakage and proper wicking (in my experience anyway), they look quite awesome. This is the classic bell cap, made by Chris Mun, but there are quite a few other options also available. Some notable options are the Steam Tuners Tiny, which forgoes the chimney for a very squat look:

The Plasma Tank is similar in concept to the bell cap, but made entirely out of glass. These are (were?) made by TrippyTips:

Bases

While it is debatable whether or not a Kayfun with a swapped base is still a Kayfun, aftermarket options do still exist. The PlasmAir AirFlow base offers enlarged juice channels, more airflow, and various other alterations to the stock Kayfun base.

PlasmAir also offers the PlasmAir RTA, which is their AirFlow base (shown above) with a TrippyTips Plasma Tank (shown a bit further above), available in a few different sizes here.

Another way to increase the airflow in a stock Kayfun is to drop in an Avid Vaper Milled Center Post, pictured below:

In my opinion, the Kayfun is at its best when set up as a mouth-to-lung tank. I don’t think that there is much of a point to attempting to drastically increase the airflow of a Kayfun, as there are other atomizers out there which do the high airflow + more watts thing better (just get a TFV4, you cretin), but the options exist nonetheless.

Chimneys

The Kayfun chimney comes in a few different lengths to suit various tank configurations- nano, full, and long. Most bell caps require a nano chimney. SvoëMesto’s own M-tank requires the nano chimney as well. The full size chimney is used with the standard 3-piece tank setup as well as with full size polycarbonate tanks. The long chimney is used with the long mode tank, which was pictured above.

Some top caps require a threaded chimney, but these are unique to the manufacturer.

The barrel section of the chimney can be swapped out with those that have various graphics etched onto them. They’re quite cheap on Fasttech.

Drip Tips

Pretty much any 510 drip tip will work on a Kayfun, so that’s all up to personal preference. Science of Vaping and JMK drip tips are popular choices here. Quite a few nice drip tips which suit Kayfuns are currently discounted on Vape International. I like the L.O.V.E. Vaso and Audio Jack myself.

Accessories

The most useful accessory bar none for any Kayfun owner is the Kayfil. With the Kayfil, you can mess with the build deck without draining the liquid out of the tank. It’s awesome. Steam Tuners sells a “Deck Access Kit” which serves a similar purpose, but it adds height and doesn’t look all that great.

I hope that the above information will help convert some of you into Kayfun people. Before you ask- yes, they can leak. But if they do, it’s probably because you screwed up.
