Yyf Grind Machine

I put a dif e yo bearing in this yoyo. Well after a few tricks it becomes responsive. I have to tighten the axel back up and it is unresponsive for a few tricks then back to responsive. Why wont it stay unresponsive?

Does the new bearing work well in any other yo-yo? Did you do any damage to the spacers when switching the bearing? if you bent or crimped the edge of the spacers even just a little bit they could be rubbing against the bearing when you tighten the yoyo all the way.

I put some new spacers in and it works great now!!! Thanks!!!
