I couldn't figger out why my new scooter kept leaning over in my wheel dock. My Bride hit the peg with her car door once and tipped it enough to set the alarm off, now that was funny I'm at the office, phone rings, and all I hear is the siren blarin' and her swearin'. She now knows where the spare key is hidden. The 03 FLHT worked fine, the 08 Ultra worked fine, but the 2010 kept leanin. Well whadda ya know differant wheels. I ordered a spacer from them and now it's back to tight as a drum. I can climb all over the bike in the dock and it won't hardly budge. What a dumbazz! If you find the same problem here's the link.
