How do you remove the rear axel on 1983 Honda 250r atc?

remove the axle nut on the opposite side from the rear drive sprocket. no need to remove the bolt from inside of the rim, just the big nut. then get a hammer and hit the inside of the tire not the rim then the whole wheel will come off. then remove the disk brake remove the caliper first then the disk. then remove the 2 nuts from the axle holding the inside nut and loosening the outer nut. then nicely pull the whole shaft out from the sprocket side. no need to remove the wheel for this step. make sure you remove the chain from the sprocket .. have fun..
