I got an authentic kayfun v4 today my very first authentic bit of kit. And was very excited to put it through its paces.I normally drip on either my zenith.plume veil.or little boy attys but wanted a nice tank I already have a subtank nano but wanted something bit bigger but not the subtank mini.so today my girlfriend got me the kayfun as an early birthday present. So I excitedly opened the box gave it all a wash in soapy water rinsed all the parts and dried them put a 1.3 ohm coil in it and wicked it. Put it all together oh yea I saturated the wick first lol filled it with some home made Cherry coke and took a nice long pull and I was gutted the airflow is crap. Is there any way of making it better.iv adjusted it wide open and it's like when I first started vaping on clearomisers.or am I just used to the airflow on drippers.plz help.
