Kayfun owners - Do you fill from the top or the fill hole?

[geetus]

I have a Kayfun 3.1 clone (hcigar), and I've always just filled it from the top. I've had a problem with it leaking from the primary airflow hole, and I think I can attribute it to filling from the top, because when I unscrew the top cap, the o-ring that fits on the chimney is so tight that it usually unscrews the base of the chamber. I pull the cap off, screw it back down, and fill, keeping the airflow hole covered the whole time. Typically, I have to twist up a paper towel and stick it in the airflow hole to get the excess out. After that, it works just fine.

Is this because I'm filling from the top, and the base of the chimney is coming unscrewed? I just found an old bottle of juice with the right kind of tip to fit in the fill hole and washed it out. I put some of the juice I usually smoke in there (I was told to use some everclear to clean out the bottle, but I can't have alcohol around - family member is an alcoholic, so I just used soap & water. It's a fairly similar flavor, so I'm hoping it doesn't taint it too badly), and I'm waiting until I use up most of what I currently have loaded to give it a shot and see if I have the same problems.

Anyway, do you guys fill from the top, or do you use the fill hole? Has anyone experienced any similar leaking issues with this atty? Or am I just doing something wrong?

I use to top fill then had some issues not holding vacuum well. It was hit or miss. Now I only bottom fill and zero issues. I also didn't like the idea of possibly tearing up the top o-ring constantly opening the top cap. YMMV.

Top fill here, no leaking. Put a finger over the airflow hole, fill, start the cap threading, flip, un-block the air hole and finish snugging down the cap.

I fill it from the top when I am out and about because I fear I would lose the screw in short order. Yes its normal to get a few drops of juice coming out of the air hole because when you cinch down the cap the air pressure created pushes the juice in the coil chamber out. I turn it upside down and blow it out into a Kleenex and I"m good to go.

I have a 3.1 ES clone and top fill is much easier for me. I don't have the proper needle nose bottle to make the fill hole work.

2 Tobeco Kayfun Lite+ clones. Bottom fill typically, Top fill I had the over-pressure issue. I don't think I'd ever pop the fill screw out in the wild though for fear of losing it just like @18wheels says. Although I think I'm going to try @SueGeo's technique now... top fill with a flip at the end to snug it down. That would be the best of both worlds (no chance of the screw going rogue and no leaking from the tightening of the top cap.)

SueGeo's method works as well but I find blocking the air hole, removing the top cap, opening the juice bottle, pouring in the juice and closing it all up requires the services of an octopus

Only had a kfl+ v2 for a few days but I'm top filling. Put a toothpick in the vent port during the process. Invert for the final tightening and then remove toothpick. A couple of drops out the drip tip and alls good. No leaks.

HCigar 3.1 KFC top fill only, no hole covering no flipping.... no gurgles either, but I use 100VG...

 

[EolasTear]

Bottom fill. I use 100% VG and filling through the bottom has always worked better for me.

 

[Trixilly]

Bottom fill. Even plugging the air hole I get juice all out the air port any time I'm no where near a paper towel. Juice running into my telescoping mod makes me

 

[cramptholomew]

I usually bottom fill, but when my original fill screw threads stripped I top filled. Put a piece of scotch tape over the airholes, did the deed, screwed the cap on slightly, turned it over, finished screwing the cap on, turned it right side up, and removed the tape. Not a leak was seen within 5 miles of my kfl clone.

I've only filled my hcigar KF 3.1 twice but I used the top fill method both times and without issue. Exactly like Suegeo said.

 

[Nomoreash]

Tobeco KFL Plus, I've done both. After filling from the top I usually get one or two drops leakage through the air hole and a gurgle for a few hits till the vacuum evens out then smooth sailing. Filling through the bottom I've never got leakage or gurgle.

3.1 clone. Top fill. Bottom filled once. Then the valve was all jacked and wouldn't stop leaking even after cleaning. Broke toothpick off inside of hole now it is sealed. No issues with leaks. I do the air hole cover then screw and flip method as mentioned above. A tip of that sticking ring is put a little juice on the o ring to lube it so it doesn't twist your chimney off when removing your top cap.

I have the kayfun lite clone and I did the same thing at first I would unscrew the top and what it does is it breaks the vacuum of the chamber and that is why it leaks out of the air hole. You should fill via the bottom screw

 

[jchamb2]

I almost always use the fill hole on my Kayfuns, but on one of my 3.1s I fill from the top because the "one way valve" doesn't work very well.

I rarely have any leaks.

Black box edition, top fill method (lazy but it works for me)..

After having leaking issues filling from top, I only bottom fill. I have had no issues since.
