Best bet if you want to see the weights of the crank halves would be to weigh them with the flywheel on and also to add the force of the timing chain tensioner and force needed to rotate the cams because all of those things have to be taken into account.
What I am trying to say here is that even if both crank halves were exactly the same weight the crank would still be unbalanced.It is quite obvious both halves are quite different weights.It is also obvious that there are other forces involved here which is the reason there are two different sized bearings supporting our cranks.
Agreed, which is exactly why we had to send everything that attatches to the crank to Falicon.
But it would be easy enough to weight while it's apart.
one side with the flywheel and counterbalance gear, other side with timing gears.
It would also be nice to see difference on just the parts between the bearings as well.
My theory is that their way off balance, and I'm not all that sure anyone ever even tried to balance them. I know the factory only tried to balance the crank weight to the piston/counterbalance setup.
