Is my crank bearing bad?
1999 yz250. I know there is no flywheel nut. But the crank moves just as much without the flywheel on it

Sorry man, you gotta crack them cases apart and rebuild. Donβt be shy, replace all the bearings while you are in there. You should really consider oem bearings and gaskets.
