A reject Rate.. THE CYLINDER WAS OUT OF ROUND.. meaning that should have been caught before it was put into an assembly.. IE Quality Control from the Cylinder Manufacture should have REJECTED the Cylinder and it should have never even made to the assembly line, let alone into a bike.
I’ve owned probably close to 100 different things with Gasoline Engines in my life, ranging from lawn equipment to Conversion vans.... I’ve had only 1, 1 foul plugs because the cylinder installed in it from the factory was not the correct shape and size...
Harley may not be as bad as the AMF years, but it proved to me, not only is their QC a joke, but taking care of their customers is too.
Still like to know what year and model it was if you don’t mind.....just curious
