So I was wondering if anyone had any tricks to loosening up the draw on a kayfun Lite clone. (Tobecco) I don't see how it would be possible to drill it out, and everything I have tried has failed. Does anyone have a fix for this?
Kayfun Lite super tight draw

You can take the air flow adjustment screw all the way out.
Also the drip tips that comes with the kayfun Lite and the Tobeco clones have a very small hole and you can try a drip tip with a larger hole.
I have one original Kayfun Lite and two of the Tobeco clones. One of the clones had a metal chip and other gunk remaining from the machining in the air chamber where the positive pin goes up to the top deck. Screw the positive pin out of the bottom of the tank 510 connection and the positive post to check for anything blocking the air flow. Also look for burrs where the air flow holes intersects the air chamber. Also check the positive pin for anything in it's hollow center which lets the air flow into the coil area. Just inspect the complete airway from the outside opening up to the coil area.

I have the version with no air control 
Next step is taking it completely apart to see if I can somehow fix it. Right now it is just about un vapeable.

take it all the way apart. the screw at the bottom has one hole thru the post. that needs to line up with the air hole on the base of the unit when fully screwed in. I have authentic KFLs and this is the case on them.
So I had a tight draw issue on one of my Kayfun lite clones and here is my journey.
I bought two Kayfun lite clones from the same vendor. I would have thought they would have been the same.....right? Not even close. I do not have the original so I am not sure what the right or wrong way was. One worked one was a piece of crap. I am assuming the one that worked was more like the original.
The one with the tight draw I took it all apart. Here were the issues and comparison of the two. The tight draw one is 1 and the one that worked is 2.
The air hole on the base of 1 was a slight bit smaller than device 2.
The juice channels were square and smaller on 1 than on 2
On 1 the chimney was shorter and the top piece had a larger ID than 2. No changing these without some major surgery.
I then took a small pin to check and see if there was something blocking the air hole in the base of 1. It felt as I was hitting rubber not metal. When I removed the center pin on 1 there was a white insulator, similar to the ones on a Protank only larger. That insulator height covered the air holes on the center pin on device 1. I could not draw through the center pin without pushing down on the insulator.
Maybe it compressed when place back in? No it was still blocked. I trimmed the insulator to open the air holes. That seemed to open the airflow. Then to really get me PO, when reassembling the center pin in device 1, the top block it screws into stripped and it would not tighten. I have worked on a lot of RBAs so I know better than to really bear down. On closer inspection I am not sure what the block it made out of but it is a soft as putty almost like lead. I can indent it with my fingernail.
So in the end I am not sure the insulator thing worked as the unit is total crap but I did put it back together and the draw was loser. Sorry if I got off topic but the whole journey started like you with a tight draw and ended up with a POS device in the garbage two hours later.
The interesting thing is I ordered two from the same vendor. One was this POS and the other is high quality and working fine. I am not even sure I have seen any other pics of a Kayfun Lite look this way. No interchangeable parts, diameters are different, O-rings are plastic, metal rings are thin and cheap. It has the SM log on the rings and only the clear tank.
I contacted the USA based vendor, we will see. I generally do not expect much and just mark it up to the risk of buying clones. This one does seem a little weird though to be so different when ordering two.
The one that worked, 2, I did blow out the air hole oin the base and stuck a small pin in to make sure the air holes lined up with the air holes on the center pin and it works fine. It was a little off and this did open the draw slightly.

Thanks for all the tips so far. I took it all apart and sure enough, there was some mystery plastic in the center pin blocking most of the two little air holes. The draw isn't quite as loose as I would like still, but it is certainly better. About the same as my ProTanks now. I think I'm going to pick up one of the adjustable Kayfuns and see if I like that better.
I recently got the tobeco Russian clone and that has a very airy draw.....I have the adjustment screw all the way tight and the draw is still pretty light for me. Anyway.....when it came in it had an obstructed air hole ( there were burs there) which made it unvapable. I had to drill them out with a 1/16 drill bit. A very easy fix. Except for the top cap washer not being fixed into place it is a 1 to 1 clone.
I have an eh pro kfl clone in addition to several real ones. The air hole was tiny and the draw was unvapably tight. I took a drill to the air hole and its much better now..still a bit tighter than I want but vapable. I've read posts like these over and over..some are great, some aren't. I wont buy another made by anyone other than svoemesto.
I plan to take it apart sometime and see if there's any trash inside. If someone without any modding inclination bought this thing, they wouldn't be able to use it.
