From the research that I have done and the thread with posts that I have read. It seems it was with the earlier production bikes. Mainly built in 06 and early 07. I have a 07 Ultra with over 22,000 miles and it just keeps getting better and better. Most of the cranks with run out appears to be 110 ci Se's. With the higher compression it seems to put too much stress on the crank. The dealers I deal with, 3 of them, there has only been 1 and it was a 110 Se.
