Good morning, Bruce;
With your comment about adjusting end play by choosing the correct thickness of the shim installed behind the bearing, or something similar, I do feel compelled to ask; "Is your motorcycle by any chance made in the old Spandau Prison in Berlin?" I ask because the setting of shaft and bearing play by the thickness of the shim is very common in the transmission and bevel gear housing of the BMW motorcycles.
