Hey guys. I've been vaping from the KFM a lot recently, and have a few observations and subsequent questions.
I have built two different coils, both on 2mm toothpicks. The first one on 30g measured 1.9ohm, while the second one, which I built earlier today with 28g, measured 1.6ohm. The second time I made sure to leave a bit of space over the airhole, and it has made a huge difference. I've been able to vape 70pg juice even at higher temperatures than I could with the first one. Right now, it's working perfectly even on the iStick, which I've learned hits harder than the MVP2, even a lower temps.
I also tested somo 50/50 pg/vg, low nic (6mg) juice on it, and although it crackled and popped more than the 70pg, I could vape the whole tank. I realized that ratio is still too much VG for my liking and the nic drop is basically unnecessary for me. I think I'll order some of my favorites like Maple Eh and Serendipity at 60/40 pg/vg, 12mg, and NO extra extract/flavor. I have learned that extra flavor, which is awesome for tanks and clearos, can be too much on the KFM. I will dilute the ones I have left with extra flavor on them with some plain VG.
This brings forth my first question. I don't believe all VG's are created equal, so would appreciate if someone could point out a really good vendor. I don't mind paying more for higher quality. My local pharmacy carries one which is 99.3% and I know I can find something better online.
Anyway, I also learned different wick lengths can make a noticeable difference. Making it exactly like Bronze on my first try yielded very good results. I subsequently made one a tiny bit shorter and it gurgled a bit more but worked. I then watched a youtube video in which the guy makes the wicks pointing upward, then puts on the logo ring, and cuts them right over it. This is the method I used in my most recent wick, and it's working like a charm. Perhaps that's the way noobs should be taught how to do it from the start.
I have one final question for those experienced with the KFM. Can it be refilled while half-full? I know it obviously can't be re-wicked, and have yet to try refilling it under those conditions. Thanks in advance.
PS- How much liquid really fits in the small mode? I've been measuring 1.6ml with a needle every fill, and wonder if I could put more in it.
