Guys
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.



I made the mistake of buying a scale from Summit Racing. It is the NEXUS brand that proform tools sells (I think 3000g x 1g.) It was near impossable to get repeatable results with that scale.
I bought a MyWeight i5500 scale. It's only around $200, but is a much better scale (5500g x 0.1g resolution) it has a ballance bubble so you can level it, and is temperature compensated.
I was able to get accurate and repeatable results with this scale.
