I got a KonKave bearing, and it makes a ton of noise when I play with it. Do I have to break it in? If so, how long should it take?
Adding a tiny bit of lube should lower the noise
Clean it then lube it.
No way a noisy bearing thread. Thought I had seen everything.
cmon man, no need to be a jerk. in the time it took you to type that out, you could’ve actually typed something helpful. 
anyways, if the bearing is loud, its more then likely dirty. even if you just got the bearing new, it just take a little dust or some loose string strands to make a once quiet bearing screeching loud. just do a search for how to clean a bearing and go from there. plus, after cleaning and drying it, I would test the bearing in the yoyo to check the noise. if the noise persists slightly, add a pin needle tip worth of lube to the bearing and that should solve the problem.
let us know how it goes and come back if you need more help. 
hi guys…
I have the same problems too
i have 10-ball concave bearing, and its very noisy
so i took it out for cleaning,
i lube it with half drop of oil…
but its still noisy
only if i put a lot of oil, it will be less noisy
but that will make my yoyo super responsive… 
Not all bearings can be silent. If you tried cleaning and lubing the bearing, but doesn’t work, I don’t know what to do about it.
time to buy some Monkeyfinger gorillus lurbricus.
it made one of my bearings for my ape x not so loud
its pretty quiet
