Hey Paul your correct and mine was a Superior kit engine they call them, sold by Superior to JJ Air Parts then to my engine builder. Where he has the option to modify cylinders, have the engine balanced, ported etc. Sad part is my engine runs sooooo good!! But I am thankful if what they state is a problem with the hardening process on the crank that no one got hurt yet from my understanding.
My engine was ordered Feb of 2013 and assembled in June 2013.
