What is interesting, is that BG's crank flange has a scallop cut which appears about where the drill bit to cut the journal lightening hole would be; mine doesn't have that scallop cut. And that cut might allow that hole to be drilled straight?
I'am in agreement that the journal hole may have been angle cut because of counter weight clearence issues,but fact that it was not finished(regardless) of where it exited there will be a true unbalance in the middle of the crank unless the material left was compensated in balance at the crank counter weights.The question is how much weight was left?If removed this would be a moot point. the crank balance would never show this unbalance area as it is balanced to the front and back axis.I will go out on a limb to say that this was not done,if it was its an expensive process and would be reflected in the crank cost.
