so if i have a b-grade with a little vibe can i tune if out…btw if a skywalker if that helps
That might be why it’s a B-grade.
Try putting the axle all the way in one side. Better?
Try the other side.
No improvement?
Try barely screwing it into one side, just enough to hold. Now screw the yoyo together.
These have worked for me a few times.
There’s other methods, often a variation of those and involve LokTite and/or teflon tape. Move the bearing a bit until you find the speed spot, then lock it down.
A lot of times, tuning doesn’t help vibe. Maybe you’re lucky.
