So, first tank filled on the original Kayfun produced leaking thru the airhole. As you can imagine I was quite cheesed off. I did it as intended, thru the bottom fill hole. After a while it stopped leaking though.
Then for the second fill I did it as I did it with the Rocket....saw that in a video clip, just can't find it now (my internet still sucks over here):
Filling it from the top and holding the airhole closed with the finger, then screw the cap on till you feel the resistance. Then turn it upside down, with the airhole still closed, and swiftly tighten the top cap. Voila....no leaking. If you do it swiftly enough, there will be no spilling either.
Currently having the gear lying down, so far all sealed. Happy now.
