I bought a Yomega Raider about 3 weeks ago. It came with what I think is black grease inside the bearing. It was starting to become unresponsive so I got some thick lube. Before I lubed it up I noticed there was what looked like black grease on the spacers and my string. I wiped it off the spacers and applied 3 or 4 drops of thick lube to the bearing. After I lubed it for a few days it was like my Raider was new again. But then it started to become unresponsive again so yesterday I applied a few more drops of lube. This time, however, quite a bit of black grease started to come out and got all over my spacers and my string. I cleaned it up and let it sit overnight. Today I put a new string on it but it's still being pretty unresponsive. It's not always coming up when I call it and I can't do loops about half of the time because when I flip my hand the Raider only responds some of the time. I'm not sure what to do. I searched Google and here at Yoyo Expert but I haven't found anyone who has had the same problem. If anyone has any advice or knows what I should do I would greatly appreciate it.
And sorry if I posted this in the wrong section.
