Attack of the (Kayfun v4) Clones!

[dave51]

All Im saying is for those that have both clones to look at them and observe is it looks as if one brand seems larger than the other
None of mine came from fastech
I have 6Kayfun 4s
1 first run Tobeco
4 Tobeco from Vapor Rangezz
1 Ehpro Tobeco 4

The first run Tobeco and Ehpro just from looking seem smaller than 4 from Vpor Rangezz

Didnt intend to start an argument just wanted to know if anyone with bot5h brands noticed the same with theirs

And for $3 you can get a caliper from Harbor Freight and measure them to be sure... Or for $10 you get one with a digital readout.

If it was really important I could just drive to the shop I retired from as a master machinist and use the QC managers calipers
I spent 20 years as head of the
Detail Department at a machine shop

Its just not that important

first run Toadbeco on my cheap China caliper
Base = 22.02
ring just below glass = 23.33
glass = 21.73
ring just above glass = 23.33
topcap = 22
fill cap/drip tip holder = 14

$10 Matte Toadbeco from VR
Base = 22.04
Ring just below glass = 23.31
Glass = 22.14
Ring just above glass = 23.35
topcap = 22.09
fill cap/drip tip holder = 14.07

Both pretty close....

thank you very much Very close indeed but enough for a trained eye to see the difference

I have a hard enough time grabbing the right metric wrench, let alone seeing a 0.02mm difference in parts.

I cant get pics from my camera to upload

Vapor Range---Ehpro----First run Tobeco

I've been getting very little vapor every once in a while since I've been using more VG dominant juices. No dry hits since I'm using TP mods. Opening the top nut seemed to help get the wick wet again but it happens more frequently now.

I unscrewed the deck and pushed all the wick to one side leaving one hole on each side open while the other hole is covered by the wick. So far, it's working great. No more dry wick and it's not flooding (one of my concerns trying this). The flavor and vapor are back!

I can't use mostly VG juices in mine , just too thick , lots of dry hits.

 

[KTMRider]

I'm currently using 80/20 VG/PG juice and getting lots of vapor and thick vapor. Better than it was before.

I use 100% PG in both my daily liquids. Never liked VG.

Yep thats the Ehpro the first run Tobeco is on the right

I thought I was the only one seeing it

Is that a screw next to the 510 on the base of the Ehpro?

Looks like a stylized EH when you click on the picture.

Edit: It is their logo.

Not a screw it looks like an it inside a circle
The Ehpro is the one gave me the most trou7ble
Unstable resistance and dry hits big time
the unstable resistance I fixed by bending the bottom coil on the spring smaller to the post
The dry hits had to open airflow all the way then tighten the nut on the 510 pin screw

I bought a few extension tubes for my KF v4's a while back with some longer glass sections but the glass was too thick so I put them away in my vape box. I had to rebuild one of my KFv4's so I took one out and tried it with the poly tank that comes with the Tobecos. When it's dry, you can see the threads but they disappear when you fill them with juice. I measured the liquid capacity and it's just over 6ml.

I really miss the fill hole from the KF3 on the K4. Now that juice bottles have the small tube in the cap it's a perfect fit that doesn't leak if inserted squarely into the KF3. You can sense the tight fit in the threads where the stem inserts. You don't have to use a syringe anymore.
