Kayfun fill hole leaking...

[mrHAIRYface]

Hey guys I'm having some problems with my kayfun 3.1 es, the airflow screw feels lose but the main problem is I sometimes get a bit of leakage out of the fill hole...I read somewhere that theres a ball bearing in there or something, but meh I fill from the top and have had no gurgle or leaks out of the airhole, so was wondering if I could permanently block the fill hole with something and with what? Occasionally I see some juice on the top of the airflow screw but as there is no juice in the air hole chamber I put this down to juice coming out of the fill hole and making its way round to the screw.

I am having the same problem, it also leaks when I fill from the top as per the videos, I don't get any leakage through the airflow though. In addition I can't seem to fill it via the fill hole....even though there is no blockage, I could at first but not anymore....don't get it.....sorry for jumping in on the thread.
