I got a Tres Leches, and I just can’t quite figure out how to fix the vibration. Do I need to take the axle/spacers out or something? Or is it a tape issue? This is a permanent vibration that makes it hard to grind and slows the yoyo down a lot on string tricks. It just can’t ever be smoothed out for some reason lol.
Have you tried tuning it? Search for tuning and you will find some useful guides.
