How many balance holes are drilled in each of your crankshaft counterweights? More than one? I would like to find out if the crank I pictured (see post #24) was only factory balanced or has been re-balanced since then. Thank you.
Thing is, the balance holes in the crank throws arent drilled to a drawing, they are drilled differently on each crank, depending on where it needed to have weight removed to be balanced. No two factory cranks would be the same.
