This tank is blowing my mind.The Erl is great for taste,maybe even a tad better than the V4,but,the KF 4 takes the prize cause of its enginneering and design.I would suggest they make a long stem chimmney like,the aErl for better flavour.One thing is for sure,this tank is MIND BLOWING..when its working at its best.
Tank you Russia and Germany for you talent in your excellent work.

BTW.i fixed the wobbly juice valve and i noticed a MASSIVE difference in perforrnance.
I just did this fix,the KF clone V4 i was having issues with the juice conrtol valve.
You will need the parts manual to do this fix.
The best thing one can do is to modify part #7 by thinning it. Mine started out at 0.044" (~1.1mm), taking it down to 0.028" (~0.7mm) allowed #9 to be fully tightened yet allowed the juice control (aka “JC”) ring to turn with just a little resistance. Some resistance is needed to keep the setting stable- too loose and it turns too easily. And obviously too tight and the JC will not turn at all. The biggest problem with tightening #9 "just enough" to allow the JC ring to turn instead of thinning #7 is high resistance! #9 has to be TIGHT!
When I first built mine, I used a piece of nickel wire across the terminals on the build deck instead of a coil- this was to check for resistance and I found 1.4 ohms- WAY too much. After thinning #7 I rechecked and found 0.3 ohms. I chalk the 0.3 ohms up to the several threaded connections used between the 510 and the terminals at the deck, the use of stainless for the 510 pin and to the steel spring- even though it's supposed to be silver plated (the original uses a beryllium alloy/silver plated spring).
So other than the above, a thorough cleaning- and I do mean thorough- needs to be done to get rid of the oil smell and the machining debris. I recommend taking it completely apart before using, down to the deck screws and all O-rings (mine was missing O-ring #19 and would have leaked like a sieve had I not caught it, the spares kit had one thankfully) in order to get it clean. Taking it down all the way is no big deal IMHO, what with a large drawing of the parts and their relation to one another to assist with dis- and reassembly
