I did my own front tire for the first time this summer, and, while I got the tire rotation right and the yellow dot by the stem ok, it wasn't until it was back on the bike that I realized the rim was reversed (brake rotor slots the other way). I did some reading and found out HD actually reversed the direction of the rotors in a noise mitigation effort (and the stamps and P/N were even left goes on right and vice versa). After seeing many bikes with it both ways and having no issues I decided to leave it that way (even though I knew that the bearings were going the other direction). I rode a 4000 mile trip with no problem. Now back I am replacing the brake pads, (thinking about just reversing the rotors), and discovered there are holes in the spokes on one side where it meets the rim, and they are in front as they come over the top and face the wind (and rain). I never noticed anything wrong, but have decided to remove and remount the tire so these holes are the same as they are on the rear rim. The air valve stem is more convenient on the right when mounted this way. Good practice changing rubber...
