Need advise on kayfun clone received from fasttech!

[umarbutt610]

Hi All,

I finally received my kayfun v3.1 stainless steel clone from fasttech. I noticed couple of issues which I wanted to bring here and see if someone has any resolution.

First issue was that the post screws had almost round heads and so the kanthal wire was not able to tuck in. Picture below will show you both the screws.

Fortunately I have a colleague who as the original kayfun 3.1 and had spare screws so he gave me couple. I wanted to know if there is some place where I can get these screws?

Second issue is that the liquid filling hole seemed to be block. My colleague has a plastic head which perfectly fits in the inlet of the kayfun to fill the liquid. He tried the same on the clone and it seemed to be block. I also noticed that the inlet hole is smaller than the one on the original. Does anyone has any idea on how to open it if it is blocked?

Thank you for reading.

My fill hole had a screw in it. Had to put some teflon tape on it to stop it from leaking from there. I only top fill my Rocket. Much easier and quicker for me.

yeah I am thinking to never use it as well for the last thing i want is to make it leak. Thats why I have not tried anything on it yet but thought may be there is a way of opening if in case it is blocked cause of manufacturing etc.

I have the Rocket from FT and it has the small screw heads too. It is a bit tricky to get the wire under them. I use small needle nose pliers to gently pinch the wire on both sides of the screw head on the inside as I screw it down. This is the result using thick 27 gauge Kanthal:

have no idea about the liquid fill hole. I always fill from the top.

I Googled and found this: Replacement O Ring and Screws for Kayfun Lite, Rocket Atomizer. The screw heads look bigger than what I have. You could email them and ask if they are the big ones.

the 3.1 has a plastic ball in fill hole you just insert blunt needle tip bottle pushing ball in then ball springs back when you pull tip out

I got the original from vape rev

then I got a clone from venerable vaping in the US quick shipping $35 perfect they work just the same
Kayfun Lite


I did meet someone who had a clone from fast tech that did not have a fill hole on the bottom

the 3.1 fills on the side, the lite fills on the bottom

Thank you for the information. I have a kayfun 3.1 and not kayfun lite. Unless and until the same can be used for both.

And this is what you are talking about the original Kayfun 3.1 or the fasttech clone of kayfun 3.1?

Yes, but i am talking about the kayfun 3.1. I am sorry if I was not clear in my original post.

Umar I have the FT 3.1 and replacing the screws is a definite necessity . I'm going to give you a link for the screws I'm using , make sure you get 1.6 x 3mm some azz on FT forum posted the length at 4mm that will cause the positive block to lift when you tighten and the screw hits the insulator and you will snap the center post , I know because I did it . These screws take a flathead screwdriver not philips but they're flat underneath and if you buy the nuts to go with it it's super easy to capture the wire , hope this helps .

Just want to add those screws work on a hcigar 3.1 as well but not on the tobeco R91% clone that FT sells the R91% screws have a different thread pitch . PITA really .

Yeah mine came with the tapered screws too. Thanks for the link Retic.

Otherwise, it's a very well made device. Will order several more, and the screws to go with it.

You're welcome , as I said above if you buy the nuts that match those screws it will ease rebuilding 100% , makes it so easy to capture the wire .

Will do. So you're capturing the wire between the screw head and nut, or using the nut like a washer?

BTW...Who Dat

I'm using the nut like a washer .

Thank you thats awesome information. Also, would you happen to know why can't i use the inlet of the kayfun clone. Will it be ok if I use a needle as recommended earlier.
