Did your machinist happen to say what was at that larger tolerance? Was it the balance between the piston/rod assemblies, or the crank balance versus the bobweight? More curious than anything.
IIRC..... SCAT says they balance to a +/-5 gram tolerance but it has never been clear to me which factor that is... or if it is both.
I think it was crank balance to bob weight ! he also mentioned that it was very common in these as he has had some pushing over 35+ grms. This is the set I purchased from summit and I paid extra for the balance job SCA-1-48035BI
