Bearing Question

Ok so i bought a used yoyo, and its almost brand new, mint condition, but the problem is my SPEC bearing is acting up…It does not spin as long as my others and it also feels like it bumps around if i hold it still, like i am going over a speedbump.
I have a question, Do i just need to clean the bearing? or is it a dud?
Thank you

Don’t clean it, just put a small drop of thin lube in it. It comes pre-cleaned without lube, so cleaning it would be a waste of time.

Thanks Samad
