Had several Kayfun Lite V2 clones, EHPRO etc. for a long time and always run into some-sort of "bad taste" issues.
A typical example would be that you puff 4-5 times, then the bad taste starts and you need to flood the chimney to get more liquid in, seeming that most Kayfuns with the smaller juice channels have an issue with not being able to "suck" juice fast enough.
Here is a solution:
1) Make a larger, like 2.4mm diam coil and space it out.
2) Cut your wick (cotton) only barely 1-2mm above the chimney. Not 1/4" or 1/2" like some say.
3) Use LESS cotton
4) After you stuffed your wick down the chimney on both sides, use a tiny screwdriver to press the wick inwards, away from the outside of the chimney ...so that the juice channels are open and no cotton is clogging them.
The key is really not clogging the sides with cotton where the channels are. (You know it works when you can shine a light from the side and you see the light from inside the chimney)
I KNOW, I must have read that many times already and this is old news, but it really works. No bad taste anymore, no need to flood the chimney after some hits. Might probably also work with more/thicker wick if you manage not to cover the holes, say, if you split the wick on both ends.
** A sign that the Kayfun is "stuffed" and you need to open the juice channels is if you puff and then you hear a sissling/sucking air sound for a second or so right after your puff. This means your Kayfun has troubles sucking enough juice. If you did it right, there should be no noise after you hit it.
