Kayfun lite 2 leaking

[deryk]

Ok this is getting old. It leaks way too often...sometimes it's fine for a few days.....refill it use it for a few hours then bam it's dripping ejuice. I have cleaned it and covered the 2 breather holes and sucked with no leaks...fill it up seems ok and bam I put it in its lanyard and get spots on my shirt. I found raising the volts helped somewhat. ....any other idea's? I'm thinking time to replace it and it isn't even 2 months old......never had leaks with my pro tank 2.

Well that's not reassuring, I've got one on the way to replace my PT2, which has never failed me either. I'm sub'ing to follow future comments, don't mind me

Couple of things:
1----how are you filling it. If you top fill you will get leaks. It is preventable but I still get a leak now and then this way. Its a PITA to bottom fill but I usually find its worth it.

2--Make sure all components are properly assembled. If the parts are even slightly askew that breaks the seal on the system and leaks follow. If you top fill, double check that you have not loosened the chimney when unscrewing the top cap...causes a leak every time.

 

[deryk]

I always bottom feed it through the fill hole and never overfill it. I make sure it's all tightened too.

 

[Towmotor]

Tight yes but is it properly fitted together?
If you are using the plastic tank it is really easy to get it together tightly but misaligned. Just today I dropped mine, that was enough for the threads to shift and cause a leak. It was still tight, needed vice grips to get the two sections apart.
Sometimes get a leak if I have too much cotton in my wick...too much juice absorbed and "pooling" at the coil, which runs back out the air hole.

 

[deryk]

Well I can check that when I get home, but I don't take the tank apart when I refill it....I could rebuild it tonight with one piece of wicking instead of 2....but that's what I saw on YouTube.

Sounds like a wick issue, you need just the right amount or you'll have the potential for dry hits or leaks. I don't know what type coil you're using but if it's a micro coil you want just enough wick to slide through the coil with some resistance then place the tails down just long enough to touch or lay on the deck without blocking the juice channels.

Could you describe the 2 piece wicking, I've not heard of that yet. Maybe I'm out of the loop...

I'm also curious, can't say I've seen that yet. Also having trouble imagining it...

I take a 4" or so piece of I think it's 1.5mm cotton wicking fold in half and put 4 wraps of 32 gauge kanthal wire around it...attach the wire to the 2 terminals...slide the wicking into the sleeve....tighten it down....trim the wicking to a quarter inch higher then the sleeve and tuck it down put the chimney piece in place....thread it back together and fill it.....not sure whose video I saw doing that....any suggestions please post a link.

Make sure the chimney seal (small oring in the bottom of the cap) is there and not damaged... it's what keeps the whole chamber sealed and the vacuum from releasing juice.

Try building a micro coil. You can re-use it for weeks or months and just replace the wick as needed. When you wrap the coil on the wick and then install there is a good chance the cotton is dumping juice down the air hole. If you build the coil by it's self it is much easier to modulate the room between the coil and the air hole, which should normally be 1.5 to 2 mm. The "tube" of the micro coil keeps any cotton (wicking material) from straying into the air hole area.

5 to 6 wraps of .32 kanthal on a 1/16 or 1.5 mm drill bit should give you around a 1.5 ohm micro-coil. there are a ton of micro coil build videos.

Here is one of MANY YouTubes for micro coils, you could search and find a different one. It may help to see it.

But the funny thing is it stops leaking at some point and then it's fine. I don't think I have a vacuum leak because hen it's empty if I cover the whole and blow through the tip no air escapes. I will try the micro coil and a single wick...can't hurt.

 

[nasca]

is it leaking or flooding? or both?

are you accidently covering the airhole while taking a pull?

 

[deryk]

Nope not covering the holes while pulling on it and the screws are almost flush with the bottom so it's wide open was halfway still leaking out the air holes hang gurgling sound while pulling on it.

Ok, I built a 2.2 ohm micro coil, 5 wraps of 32 gauge kanthal wire over a nail that my 2.5mm cotton wicking will fit through...I am going to have to pick up some organic cotton balls one of these days ... heated the wire real good and compressed it real nice. So far so good..but usually when it happens it happens a little later not immediatly after I bottom fill it. Now it was mentioned in the video that too much cotton can draw in too much juice...so maybe the dbl layer of cotton wicking was too much. I am annoyed my leather sheath I built now has dark spots on either side from the e-juice dripping out of it... oh well might have to build a new one this weekend.

oh should I move down to 28 gauge kanthal instead of the 32 gauge?

thanks

I use 28g or 30g in my Lite+, I try to keep my ohms at around 1.4-1.5 if it's on a 15w regulated mod. Mod range | Steam Engine | free vaping calculators This calculator will show you the "sweet spot" as a guide to your build for your mod. But Kayfun's like the 1.5-1.8 range.

I'd go with 30ga for regulated mods, 28 will work but unless you're wanting to build in the low 1 ohm rage the lag time might be a little high. 30ga will heat up faster and good for builds from 1.5 into the low 2 ohm rage. Either will be better than 32 for micro coils, imo it's to thin and springy and harder to work with for micro coils.

 

[deryk]

I definitely agree with you on the springy'ness lol...I couldn't get it as tight as the video showed. I ordered some 28 gauge this morning off ebay and will make a new one next week with some organic cotton balls. I have a Provari V2.5 so no sub ohm'ing for me.

So far so good... will update it if it starts leaking again or when I get the new wire.

thanks folks!
