The problem was the rear outer cam bearing failures. On December 14, 1999 the Motor Company made a production line change to go from a ball style bearing to a roller style cam bearing. They also changed to a cam support plate that had a slightly larger hole machined in it for the outer cam bearings (reportedly because they thought the zero tolerance bearing fit squeezed the bearing helping it fail). They later changed back to their *original* cam support plate with the zero tolerance pressed in bearing (feeling that the first revision wasn't necessary after all).
Call harley and ask if the bike was produced before or after this date. If produced before, I would recommend changing the rear bearing to the roller bearing style.
Harley was giving the 5/50000 on the original bearing to avoid having them changed out knowing full well the majority of riders never put 50000 on a bike.
Hope this helps.
