a couple of grams one way or the other is not a problem--thousands of race units are done within a few and they run fantastic. It is one of those things that just won't matter. Shops use expensive balancers that can find a paperclip taped on a crank but the scales most use are China specials that read different every day you turn them on--an experienced shop that does them everyday will send out a good balance job--it is technique and experience. Even if the scales say 782 today and 783 tomorrow on the same part it will all work out fine.
