Certainly phasing is important, for the reason you outlined, Jim.
But, I don't see any reason a flange couldn't be out of balance enough to
make a difference if it was turned 180 degrees, especially if you have it on
a balancing machine. I tend to doubt that Triumph balanced them that
accurately, but it's certainly possible.
