Ilyy Sakura Help

For some odd reason, my fully broken-in Sakura has been acting responsive lately. I can’t even do a finger grind without it smacking my knuckles. Any tips or help? ???

I had trouble with my BvM doing that. Here’s what I did:

Romove and clean the bearing using mineral spirits
Use a qtip and mineral spirits to clean the bearing seat
Replace the string

Thanks man ;D. Any idea on why this happens?

String bits get stuck in the bearing seat.
