Just tried the Plasigauge on my crank mains I have the bearings as follows.
Crankcase Code CAABA

1-Black, 2-Green, 3-Green, 4-Brown, 5-Green.

All 5 mains are reading the same at 0.0015 thu / 0.038mm  on Plastigauge chart after torquing up the mains bolts.

That to me looks like 38 micons all round so am happy with the new shell colours.

Next I will be checking the big ends.
