The oil seals definitely blew. The right ones was leaking and wouldn't hold air. Then the next day, the left one did the same thing. It was a bouncy ride home. Those instructions on replacing the seals are the same ones that came with the seals but the tech support guy said that was wrong and I should have put 6 oz on instead of 2 oz. I searched high and low, and as you can see, there is no definitive answer. The 416 series must come in many sizes and flavors. I read in a Harley forum that a guy puts 11 oz. in his.
