    I'll be honest that I'm surprised they agreed so quickly to send a new unit instead of thinking that it was something that I was doing wrong. I broke it down twice with the parts breakdown in front of me and made sure everything was tight and put together correctly. When I get the new one I'm going to completely break it down, clean it, and put it back together so I know everything is correct from the beginning. So many people like these that I figured it couldn't be this hard to make it work.

    I finally got my new kayfun 4 and got it set up this morning. So far so good. I noticed right away that the juice control turns a lot easier on this one. I'm convinced that the first one was a lemon.

    I put a Ni200 build in mine this weekend, 8 wraps of twisted 30g on 3mm ID came out to 0.16 ohms. I did the tubbyengineer (Planet of the Vapers) mod of bending the end of the spring a bit to make it smaller where it goes onto the center post.

    It's nice to run the KFV4 in all Stainless Steel mode. :)

    ETA: Correction and link to post about the spring.

    Hello, HIt! Glad you got one that's working. I only have the Tobeco clone I got on sale and it's been flawless.

    Lemons happen...

    Enjoy!

    I about went nuts trying to get the first one to work. I thought about ordering an oring kit but had just bought it so I talked to the vendor and after a couple conversations they decided to just send a new one.

    Thinking I'll also try this method for stable resistance in TC, full metal jacket for the 1st time-super!

    Trolldragon, I'd love to read that post on UK Vapers by tubby engineer before attempting this but not having any luck finding the post; do you have a link to it as my search came up blank!

    I'm also wondering if this will work with the S kit installed since there is no afc screw?

    EDIT: Ok, I found the post on Planet of the Vapes, but not UK Vapers.
    Really want to solve the resistance issue so will have to sign up there!

    My bad it was Planet of the Vape and not UK Vapers, sorry.
    Original post corrected and updated.

    There really is not a whole lot of info, it is basically all there in the first post.
    Kayfun 4 - Resistance stabilisation.

    I did this part right here.
    The aim is to decrease the diameter of on end of the spring so that it push fits onto the central airflow post (around the outside of the bit with the airflow screw). This improves the connection massively and ensures a fairly stable reading.

    It will work with the S Kit as well since you are not involving the screw at all.

    Quick update. I did this little spring mod on all 3 of my KF4's; very quick and easy. It does stabilize the resistance considerably so, whether you use kanthal or nickel, a harder hitting atty is what I found is the result. Thanks guys for this fix. @TrollDragon @KTMRider @Tubbyengineer

    Hi guys, I love my Kayfuns V4 but I couldn't stand that it has so many separate parts in the way of positive connection that could potentially loose connection:

    So, I decided to replace them with a single, solid positive center pin:

    Loosing these extra parts on the same time:

    It looks like this, when assembled:

    And to increase an airflow, I made some more:

    And you did this w/ a Dremel and jewelers files? :D:D

    Nice! Really nice work.

    Excellent Work!

    So the question is now, where do we buy any of these most excellent upgrades? :thumbs:
