Last month I bought a SPEC bearing for my Lyn Fury.The first 2 weeks everything was OK,the sleep time was longer,but now…the yoyo is mega responsive, :-[ it makes strange sounds and it sleeps a lot less . :’( :’( :’( Can You tell me what sould I do ? ???
Sorry if I spell things wrong
Thanks a lot !!! 
Yup, it sounds like you might have gotten a piece of dirt or something in your bearing. Clean it, and it should be as good as new. For a guide on cleaning bearings…
I have heard this from other SPEC owners as well. Some people just continue playing with it and it works out. Try doing that. If it doesn’t work, clean it.
