The other day I got my center trac bearing and put it on my Dv888… I decided to put my spec to some use on my DM for 5a… But the DM played more horrible than I usually am at 5a… So I put the spec back on the Dv888 and it played crappy too… Yet both yoyos played fine with the Center Trac… I listened to the spec and it makes this funny rattling noise and spins fir about a fifth of the time it usually spins… Any help at all to fix it would be appreciated!
Edit: the spec played fine right before I took it off the Dv888 the first time
Its highly unlikely you knocked out a ball without much damage being done to it. The rattling is most likely either junk, or the bearing being too dry. Deshield the bearing. It all 8 balls are intact, I was correct, and you need to clean (and lube) it.
