Kayfun V4 from The Canvape Store

My thanks to Randy Peacock at The Canvape Store for helping me out with this. I am no longer able to build (or wick) coils. When I dropped by the store, Randy told me that he provides tutorials to buyers on how to make their own coils and wick them. It's all part of the service, he said. And, he sure knows his stuff. I told him what the final resistance I wanted (0.8 to 0.9 ohms) and he pulled out the right guage wire, some fresh Japanese square cotton pads, and went to work.

The final build turned out to be 0.89 ohms ... confirmed on he resistance meter, and on the advanced personal vaporizer.

The Tobeco Kayfun V4 is just released and The Canvape Store carries it. It's a 1:1 clone and the quality is simply outstanding. There are a lot of parts on this with ground-breaking features and every single threaded part is buttery slick smooth. Incredibly smooth.

Here is the list of all new features:

  • Top filling ... without the air lock and vacuum leaking problems
  • Air flow control with double the air flow at even the tightest setting
  • Adjustable 510 connector
  • Three tubes (tanks) included: stainless steel, PMMA full size, and glass
  • Adjustable liquid flow (wide open to completely shut off)
  • Dual coil support
  • Entirely new liquid flow system

The look is spectacular. I asked Randy to take his time so that I could watch every step of the process. I was impressed with the quality machining on every single part – everything well machined, well polished and super clean.

There is no manual included and the only spare part is a spare air flow spring included in the package. So, here's a few tips:

1. To adjust the air flow, you have to remove the 510 connector pin (flat screw driver) from the bottom or remove the bottom base to access the air flow adjustment – also a flat screw. Counter clock wise to make the air flow tighter, clock wise to open the air flow.

2. The ring that has the four air flow holes is actually to adjust the liquid flow.

3. To fill from the top, you can either remove the flat top portion, or the drip tip adapter. You only need to remove the drip tip adapter (that is the intermediate size stainless steel portion that the drip tip sits into).

Randy built the coils using a mini screw driver ... I didn't measure it, but my estimate is that it was a 3 mm shank. The coils glowed completely at the same time (with a bit of adjustment). At the right is a picture of the coils in place and wicked with Japanese cotton.

It's a really nice setup and much easier than the older style Kayfun. There is even more space to work in. The chimney is entirely different ... what you see at the right is a "container" sleeve to hold the wicking in place. It's covered by a one piece pyramid style chimney with liquid flow holes in it. At the picture just above the one to the right, you can see that just below the ohm meter.

The liquid does not flow to the coils like previous versions of the Kayfun. It actually works more on a gravity basis to flow downwards, and then by vacuum to get it up through four individual liquid channels. Wicking does not have to be as precise and fussy as previous versions. Plus, there is now a liquid flow control ring ... you can see that in the picture at the right. It's the indented ring at the bottom (you can see an air flow hole in one of the indents). When you turn that clockwise (looking at it from the top), it opens the liquid flow, turn counter clockwise to close off the liquid flow. That's a better system than just blowing through the drip tip for any liquid that may have gotten into the air flow channels. This way, you can reduce liquid flow and open it as needed.

The Tobeco version, as indicated at the top, is a 1:1 clone and even duplicates the logos and marks. Although my pictures show the full stainless sleeves used for me, I did end up replacing the stainless steel center section with the glass tank so that I could see remaining liquid levels. After all, this is using Japanese cotton, no need to wait until you get a burned taste to have to refill liquid. I'd rather preserve the quality Japanese cotton and see when I need to add liquid.

Now the practical side: the Kayfuns are known for incredible flavor rendition ... and the Kayfun V4 is even better. You can use this as a general purpose tank system since it is so easy to refill or you can make this the corner stone of your hobby. With low resistance coils and high wattage, this is a cloud machine. Even though not the lowest resistance, at 0.89 ohms and 50 watts this was chucking clouds and I was impressed. Turned it back down to 15 watts and I still got all the flavor and vapor that was still thoroughly satisfying.

So, what's the verdict? Is it worth it? I had stopped using the Kayfuns for awhile. After I ended up with plastic tank melt down, I switched to glass-only tank systems. I suppose I could have purchased the glass tank option, but I really didn't want to spend any spare change on something that I think should be included in the package to begin with. Until the Kayfun V4 that came with a stainless steel tank, a PMMA tank, and a glass tank, I had no motivation to pull out the Kayfun again. This Tobeco Kayfun V4 is a game changer. It combines form with function and provides a safe vape. The Canvape Store offers this at an incredible price ... so, yes, it's a must have.

And, PS, again: my thanks to Randy at The Canvape Store in Scarborough (21 Canadian Road, Unit 1) for his help. I haven't been able to build (or wick) coils for a few weeks now and his help was excellent. According to him: nothing special, he offers to tutor buyers on building and wicking their own coils. Get down there and take advantage of this. It's a great way to get the low-down on "how to" do it yourself.
