Kayfun v4s kit spitting issue

[zookzor]

Hey guys, I've been vaping on my Kayfun v4 for about a month now and I recently installed the 4s kit for more airflow. After trying it out I've noticed I've been getting a lot of spit back of juice into my mouth. I've never had this issue with the v4 which is why I love it so much cause other tanks give me this problem. I run a 28guage 1.1 ohm build 2.5id and the coil is slightly spaced. Any input would be appreciated!

Best Regards,
zookzor

I am fairly new to rebuildables but I am a quick study. It seems like the most typical issue on the KayFun 4 is a loss of vacuum in the tank. Even if it looks like the seals are intact, it doesn't take much to cause an issue. Strip it down, clean it, and carefully reassemble it being care to not over tighten (yes, this actually causes issues).
It took me a couple weeks to get the hang of it, but the Kayfun 4 is an amazing piece of technology once you get it down. I never had airflow issues with mine, was it actually a problem for you? There is a delicate balance between airflow and vapor production. Sometimes more air is a good thing, sometimes it just causes other issues.
I hope I was able to help. I'm surprised you didn't run into the tank wobble issue, that had me fuming for a couple days.
