I noticed a little side to side play in the front wheel on my XR650R. I have had a set of Supermoto wheels on it for a few years and they have no play from side to side. While swaping wheels back to the stockers I noticed about .030" of side to side movement. I took it a part and looked eveything over and everything looks fine. I thought it might be the wheel bearings or the spacer in the hub so I popped the bearings out and they are fine. I put all the parts spacers and bearings on the axle and installed it in the forks, torqued it down and the slop is still there. All the parts can slide a little on the axle. I don't know if this is a problem or not and if it is I'm not sure how to get rid of the slop without machining new spacers.
