Most Crank builders do not cam cut the counterweights any more. I think Moldex still does. Of course they don't care because they can charge you more to balance (mallory metal)

If you think about the shape of the piston you might be able to just Chamfer the counterweights and get the clearance you need and even that could be done on an as needed basis similar to a cam cut.
