Updated Measurements
Here are two sets of updated measurements recorded with a Fowler micrometer. I'm feeling much better now, given the fact that machinist who will be doing the balancing and crankcase assembly said the rod journal specs are: 2.0855 to 2.0862 inches.
As you can see from the photo, I measured twice. One day while in the garage where it was 82 degrees Fahrenheit. Then a few days later, I took the crank and micrometer to the basement of my home where it the temp stays steady around 65 degrees Fahrenheit. I left the parts down there to adjust to the temp for 2 full days.
I'm documenting the measurements in plain text here too, in case this image doesn't resolve one day in the future. The final measurements will come from the machinist, but I don't anticipate there being any major discrepancies.
