I have been studying hard and think I have my answers now.
The point that I think Fixkick was making is the same that a machinist just explained to me, that is:
Machinist orders the bearings that are a little too big and then makes the crankshaft & housing bore fit the bearings.
Still strange that bearing sellers do not always post the size info for their bearings.
Anyway, after careful measuring I find that my crankshaft journals are all the same and within specs and not out of round. Also, all of my housing bores are exactly the same to within less than 0.0005". They are all just a tiny bit bigger than the biggest size in the service manual chart.
After comparing carefully the 9 size combinations, I have decided that if I get the "yellow" bearings (all 5 the same) then they should work without having to do any machining to make them fit. Important to me because I don't have machine shop.
Then I did a lot of online shopping (hours and hours).
I found that Suzuki does still make the color coded bearings because they are used in a variety of engines on cars, boats, and motorcycles. Problem is that they changed the part numbers for these color coded bearings. Searching for main bearings does not work well, but searching for the part number does work well. The Suzuki color coded main bearing are sold individually (not in sets of 5).
I will attach screenshot of my study notes along with my shopping notes. They might be useful to someone?
