When I replaced the bearings in my old 250ES I had tighten one side a little then the other a little. I repeated this until I got them tight enough. The first time I tightened one side down all the way then the other. It wasnt right. The swingarm wasnt equally spaced on both sides either. Check the spacing on each side to see if they are equal. If not this may be your problem.
