Got one in the mail today. Have it put together but won't try it for another day or two because I got some other new stuff that I'm testing to be sure it works properly.Not a problem.
Now all of FT BARREL (GRAFFIX TUBES) are sold out so you have to get tge barrel with Nano chimney. When you get the pieces remove the pointed hat and screw the barrel tightly into the bell cap. And the base into the barrel and bell cap.
As far as i am concerned that little $1.69 bell cap PEEFECTS the kayfun.
Took me a while to remember you told me I didn't need to use the chimney from my Lite Plus V2, only the barrel. Once I recovered from that brain cramp, it fit together nicely.
