I've just got a new kayfun lite clone from a well known Chinese vendor. It's OK I suppose but even with the AFC all the way in its still a very airy draw. The flavour is there and the vapour is all right but there is no resistance in the draw at all. I've tried .3 mm Kanthal, twisted .2mm and .3mm, a .3mm double barrel and even a triple twisted .2 mm coil all at 1.6mm ID but have had no improvement. Reading some older posts it's been suggested that increasing the ID may help. I'm a bit sick of trial and error with the thing so I was looking for an answer as to what effect this will have on the electrical resistance this will have? Will I have to go up or down on the number of turns to keel my resistance at about 1.2 ohm. Any other advice would be very much apriciated.
