I am in the process of building a 87 Honda CR500 motard. (I am having a the stock hubs laced to 17" wheels). I took the rear wheel off a year ago and removed spokes/rim. When I mount the hub on the rear axle, with the new MSR spacers (new spacers are the same width as the originals), there is approx. 3/4" of side to side movement of the hub on the axle. When I torque the axle nut, the hub still moves side to side approx. 3/16" Also, it doesn't seem right that the swingarm should bend/flex this much when tightening the axle nut. Is something missing? Any ideas?? Thanks for the help!
