I just got a kayfun lite + in the mail today. Set it up, its vaping good. One thing that is bothering me however is there is this high pitch noise when taking a drag. If i draw kind of...less hard it does stop. But when i suck at regular strength, it whistles. I hate noises like this, is there any tip or pointers any of you guys have for me? This is my first kayfun style so im kind of lost.
