Hi,
let me share my detailed experience of Kayfun 5 LEAKING, GURGLING, FLOODING, SWEATING and how I totally solved it:
1,5 months ago I received my Kayfun 5 and entered in contact with the vaping experience and vaping world.
I lubed the o-rings and started using it.
Problems:
- sweating a lot around the air holes and 510 pin
- permanent liquid dropps around the air inlet holes. Impossible to use without a napkin
- leaking (just a little) when held horizontally, impossible to hold in the pocket with liquid control open
- flooding and gurgling or dry hits - almost impossible to set the right liquid amount
- cotton got dark braun almost black after 1/2 tank. When I washed the cotton it got withe again.
I tried all possible wicking methods and coil configurations etc just to see it work as some are describing it and nothing worked for me.
I took all o-rings and inspected them with a lens, nothing wrong!
I verified on svoemesto's website if it is original Kayfun 5 or I have been cheated with a clone! It is original. Checked 5 times because I couldn't believe it!
I got pretty desperate and raised the money for another vaporizer but before ordering a new one, last evening I thought to try a last thing and alleluia!!!
Solution:
I took the spare o-rings received with the Kayfun 5, lubed them well BEFORE INSTALLING on the Kayfun with special lubricant for food industry. I put oil on all sides of the o-rings.
Then I dismounted the old o-rings, lubed the new ones again, just to be shore, and installed them.
Since then no more sweating, leaking, flooding, gurgling, dry hits or dark cotton! I'm at the second tank already.
It is a TOTALLY different Kayfun 5 and liquid control works very easy and smooth. same with the air intake ring.
It has no relation now to the way my Kayfun was working and feeling 2 days ago!
I lubed the old o-rings in excess at least 10 times with the same lubricant but I had no improvement so I can't explain what was really wrong with it because no o-ring was damaged (at least not visible with a magnifying glass)!
Monday I order 3 more o-ring sets.
Each month I will dismount the o-rings to lube then reinstall. No more lubing with o-rings installed!
I hope my experience can help other Kayfun users.
