sometimes it's hard to see the forest because all the trees are in the way, without realising the trees are part of the forest.

what that means is either you had a issue and fixed it but don't believe you did fix it so are convinced it's still got issues OR you still have an issue that is un diagnosed and not yet fixed which re-enforces your belief that an issues exists.

you may have to first as Fog said leave it alone and see if it cures itself over time. if it does you know you fixed the problem. if it doesn't then you may have to revisit what caused you to delve into the water pump in first place. and look for other problems you missed first time round.

not sure it's hard to see with all that gunk on the mating surface, I believe the weep hole is somewhere in the middle case that separates the coolant on one side and oil on the other side.

looking at that case is the very reason I disagree with fog about gaskets if Kawasaki put one on it should have one on.
and nothing else, ok so a thin (2mm bead in middle of the sealing surface) may seal the case. but who knows to do this,
when you say just use sealant it more or less just gets slapped on 1/2in thick yes it seals the case but when it oozes out where do you think it goes yep in all the places it's not supposed to go.

I have never used sealant if a gasket is supposed to be used in places like the water pump, it not saving money in the long run with all that goo floating around everywhere. all my pump repairs get gaskets nothing else new seals and no issues. hell there not expensive you can even buy gasket paper for a few cents and make your own.

first part, yes.
second part, if you have fixed it why do over it may be fine, run it for a bit and see, if it's not fixed then yeah do over checking all the stuff you didn't check last time
third part, correct.

ok. just to add, the last time I did a water pump (about 2 years ago) due to a small weep from one of the transfer pipe O rings,(needing the removal of the pump). I bought all the stuff beforehand seals o rings gaskets, (I usually make my own from gasket paper) stripped it cleaned everything and reassembled with new paper gaskets, filled the coolant ran the engine through two heat cycles let it cool topped up the expansion bottle checked for leaks (none found) that's it.
running two years since no issues. coolant is even still clean.

I doubt if tightening would help much if at all, and the threads on that shaft not the strongest on the bike. I would leave it a while longer to see if it stops completely why disassemble it all again to do something that might not improve anything.
if it doesn't stop completely after wearing in the seal, you may have other issues not yet addressed (you did give the water pump quite a whack) but for now it seems to be working.
just my opinion of course.
