Regardless of what ever comes out from your dylema, I would seriously consider checking the forks rear swing arm and frame; It all points out to be a totally missaligned front and rear wheels... by the way, have you crashed the bike lately?
I have also heard of several Springers that came bent from the factory and the owners received a new frame
That bike cannot handle very well as it is. Does it also wear the rear tire the same way? I bet it doesn't.
I put a post about checking the wheel alignment in some other post, but can't find it now; it's somewhere in this forum.
Good luck

The bike handles great! I was on Route 66 near Grand Canyon, took her up to 110mph and not a shimmy but plenty of throttle left...BTW AZ takes care of her Route 66...New blacktop, clean and smooth...Great ride....
I've never crashed, bumped or kissed a bumper with the bike...The dealer stated there is no alignment to do on a springer, so their master mechanic says....Rear tire has normal wear and wears evenly....Frame doesn't seem to be bent or forks either....Brakes on right side of tire, same side that is going bald if that makes a difference
Maybe another dealer is needed.....
Anywho, I followed WFP's link and I travel Highway 1 on my commute, not 5 or 99......I don't even feel any pulling to the right...
Thanks for info and replies....If the answer is found, I'll be sure to post.....
