I am wounding if you all would replace there bearings or clean and re-grease? There is no slop and before I removed them they moved nice and smooth. I'm going over the bike because I'm selling it (06 YZ250) and don't really feel like spending the money if I don't have to. We all know the YZ bearings get dirty fast. I clean and grease them at least once a year and some times twice. They have not be replaced in at least 3 or 4 years(maybe sooner I don't remember).
