These cranks are externally balanced and use a neutral balanced spacer and balancer like any other non-SCJ 428.
I do not consider his statement more accurate, and when I look at the website, I think they confuse people. I am betting you'll agree when you see the pic below.
I know its semantics, but once a crank needs an offset weight, its an externally balanced rotating assembly.
I know I am preaching to the choir, but SCJs are externally balanced that need weight on both ends, a CJ/PI/410 is externally balanced that needs weight on one end. I understand the Eagle is designed to be the latter
No doubt, saying its internally balanced on one end but not on the other
CAN be explained, but it's not correct, nor is that a reason that it cannot be internally balanced like they told me, guys are doing it all the time
I just don't like when terminology is misused, if someone clicked on that website to order one, the site below leads them to believe its internally balanced. See the screen capture below. For them to come back and say that this means its "internal on one end" is ridiculous and a play on words IMHO
