“I have a 2003 harley electra glide classic. I had 2957 miles on a rebuilt motor done by a harley certified mechanic. This is a touring bike and is not abused, I am 59 years old and drive it like a mature adult. The crank shaft on my bike broke on the right side of the motor at 78 miles an hour. I was lucky that the bike did not wreck or a piston go thru the case. I took the harley back to my mechanic and when he took it apart him and the machinist checked it out. Appears that the crank had not been tempered correctly, looked like it had been tempered too much. …”
