So I just got my new Tobeco Kayfun clone. Pretty excited when I got it, sad to say that bubble would soon burst. I decided to go ahead and vape it right out the box with the coil that was already built with it. The ohms checked out at 2.0, I dripped some juice on the wicks, closed it and then filled the tank. the first 2 hits seemed fine but just burnt after that. so I threw the coil away and decided to build my own. I washed the while tank off first soaked it in hot water for about 5 minutes and wiped it all down. building the coil: 30 gauge kanthal and 3mm silica. about 6 wraps with the kantal around the screwdriver that came with it, fed the silica wick through. Checked out at 1.8 ohms. not bad. But I still get the burnt taste helpppppp.
