ive also found that if u fabricate a home made number plate it can have the same effect .. specially if u have more letters/numbers on one side : )
I just move my wallet to the other pocket.
I believe the Deluxe is pretty balanced. The 2019 model I checked for verticle balance looked pretty good. I found that the new Fatboy and Breakout have the issue. Might have something to do with getting the drive belt out enough to clear the wide rear tyre. Maybe these models have more weight hanging further out somehow on the left to achieve this.
