Hello all, I have 2 Russian 91%'s one with a floating pin and one with the standard screw pin. I use a Hana mod 30 Watt but keep it on 7 watts all the time. Anyway, I keep getting a burnt taste after about 15 drags on both of my set ups. I have changed coils, cotton, changed all seals etc and it keeps happening on both of them. I think at this point, I am just going to sell them and stick with my nautilus. I have cleaned them both with vodka and nothing seems to work. Has this happened to anyone else? Is there a shelf life for the Russians? Thanks in advance for the input.

Could be using to much cotton. You need just the tails to go into the channels. Don't stuff it full of cotton.
That could be a possibility. I am thinking of getting the Orchid V2 now though and hopefully I won't have that problem. Thanks
Thanks, I definitely don't use too much cotton. I even took them both to a vape shop and had them do the entire set up but still had the same problem.
A picture of the way your wicks are setup would allow us to help you much better.
Also, what's the pg/vg ratio in the liquid you're using?

"burnt taste after about 15 drags"
The cause is most likely poor wicking.
Caused by:
too much or too little wick
air flow adjusted to 'loose' (airy) resulting in poor internal vacuum.
Too strong and/or long a draw
chain vaping

Besides changing the o-rings, have you checked them? The seals should all be air-tight. Symptom you described sounds like a poor vacuum, which could indicate a bad seal between the top cap and the chimney.
Full disclosure: I shelved my Kayfuns a few months ago. When they're working great, they're awesome. But when they're not working correctly, troubleshooting is a PITA. You have to drain the liquid and take it completely apart to see what's going on.

Joe, you are right. At first, my Russians were awesome. Now with these problems, having to take the liquid out etc, I think I will just get another Nautilus or something similar and see what I can get for the Russians.
Got to be a wicking or hot spot. An O ring problem would cause leaking and flooding.
High vg and bad juice channels could also be the problem. Sometimes clones have poorly machined juice channels that don't allow enough flow.
I use long tails which run in a curved shape from on side of the ledge above the channel to the other side, basically they lay flat above the channel.
This seals of the vacuum pretty good, and they wick really well. I use enough cotton that there's a resistance when sliding it through, but if i would dangle the base while holding the wick, it would probably slip through.
It's not easy finding the right amount, but once you get there it's a great device! Haven't had any dry hits or leaking for at least half a year =)

Hello Mark, something is definitely not right here. The Kayfun Lite / Russian 91% are considered one of the best attys made. It can and should be able to destroy a nautilus in both taste and performance. You'll find many experts here http://www.e-cigarette-forum.com/forum/rebuildable-atomizer-systems/436118-kayfun-lite.html
You'll need to include details about your coil there is not enough info in this post to get the best help.

My pleasure, hope you get it sorted! 
FWIW I have both, the nautilus is pretty good right out of the box but it can't be much made much better. The R91 may take some work to dial in but the range of tailoring it to one's taste is extensive. Once dialed in it's a monster and keeping it there is not hard.

How loose is your air draw adjustment screw set at. If you are using thicker liquids, might try adjusting the air flow a bit tighter to help pull more liquid to wick into the chamber, and if this is the issue, you'll need looser wicking as well to be able to wick to the coil properly.
