Dry Hits, Burnt Taste? Try a Spaced and Larger Diameter Coil

[flexy123]

I had such a hard time sometimes with my kayfun, ESPECIALLY with VG juices, not even 100% VG but my standard 50/50 VG/PG. Basically, the Kayfun was VERY prone to getting dry hits and burnt taste.

After testing lots of different wicking techniques and coils...it's actually pretty simple.

Make a larger diameter coil! I went from 28ga 1.5mm diameter to 28ga 2.4mm diameter. And SPACE the coil a bit. Not much, maybe 0.1mm or 0.2mm so your coil doesn't touch.

While this might create a small drop in flavor (not sure about this, might be placebo I can now chain vape the same VG/PG juices -NO DRY HIT and BURNT TASTE whatsoever. Very smooth vaping experience!

The wick is the exact same as I had before, simple standard wick, down to the deck front and back.

(If a spaced coil does really result in slightly muted flavor I have to say that I prefer "slightly muted flavor" over awful burnt taste any day! Seriously before I made the new coil it just tasted awful since it only took a few puffs and I got the awful burnt taste constantly. Yes, wicking can also make a big difference, but I think it's the spaced coil which now finally makes all the difference!)

Edit: With some DIY juices I also run into black gunk VERY QUICK...sometimes after an hour or two. With a spaced coil it's said that it also reduces the chance for black gunk.

Atleast now you'll also be able to see when the wick gets old and starts to darken ready for a re-new.

Well, I find I get better flavor from a spaced coil than a contact coil. I use NET juices and spaced coil also stay gunk free longer than contact coils. As for wicking, with cotton I find more is better.. Diameter, well I think this really affects ease of wicking more than any performance issues. But I do believe the bigger ID coil allows you to run a hotter coil, without increase in the heat of the hit.

What are you using in your DIY juice that gives you a black gunk build up? The only time that happens to me is when there is sugar in a flavoring, or purchased juices with sugar or too much sweetener.

Maybe it's both things. The wider coil might benefit better/easier juice flow (because the wick isn't as tight)...and spacing out helps, well, more even distribution of heat.

I noticed problems with my Kayfun when I do 50/50 juices (as opposed to PG only), it's definitely wicking slower and has sometimes problems because the EHPRO Kayfun V2 has really tiny juice channels...and black gunk, well it depends what I mix, flavors etc. how you say already. Have to say VERY satisfied now with the slightly spaced coil, now just looking for a screw or something so I can make evenly spaced coils easier.
