The first twin cams built for the 1999 and early 2000 models had an issue with the cam bearings. I had a 2000 model and had an upgraded cam installed. My mechanic told me that Harley had released a "fix" for the cam bearings (not a recall, however) which had given problems but that I didn't need it because my bike had the new and improved style. My bike had been manufactured in October of 1999.
I found some reading material back then about this problem. If I remember correctly, Harley quit installing the defective setup early in the 2000 year model bikes.
Rumors being what they are, I wouldn't be surprised if that is what you are referring to. If so, your bike certainly isn't involved. I haven't heard of any other issues since that time.
I've owned four twin cams and ridden them all over the country in all kinds of weather and at all speeds. They are a solid engine. Enjoy yours and don't worry too much about what might go wrong.
