I have a 99 K1200LT and while riding yesterday I noticed a noise in the rear wheel. The further I went the louder it got. I don't see any oil leakage on the rear drive so I don't think I have a bearing issue. I put it on the center stand and there is no slack in the rear bearing. Is it possible that the rotor has come loose and is rubbing the caliper? It seems to be scrapping only on one side. I replaced the rear pads about 1 month ago. I can see on the inside of the rotor where it is contacting the caliper.
