There is a 50% factor of the reciprocating weight, so the "net" to the bob-weight is 4 grams. Personally I wouldn't worry about it too much because some engine builders overbalance and/or underbalance anyway.

However if your worried about it,,,, then the best thing IMO is to lighten the piston by 6 or 8 grams. The area to lighten is around the pin bosses and also underhead. Most knowledgeable machine shops can do some weight removal for you. No need to mess with the crankshaft or mallory metal.

8 gr per piston .
there is 2 pistons per crank pin .
8 grams for b/w
