is a regular kk bearing responsive on an 888 when you first get it?
It doesn’t really matter what yoyo you put it on. It probably won’t be responsive, but it could be.
It depends on how badly thick lubed the KK is. Mine came responsive. A good clean/breaking in should make it unresponsive.
Nope. Sometimes little specs of dust or dirt can often get caught in the eight8eight’s bearing seat.
It shouldn’t be.
If it is, clean it! It’s probably because it is heavily lubed.
