Crank bearings good or bad

You can't feel any of them with your finger nail so they don't appear to be deep
McCabe-Thiele (Ted):
It might just be burnt oil (carbon) deposit on the journal - try cleaning it off with some Brasso cloth. I had it on my 400 big ends and on the conrod where the shells sit.
Bryanj:
No you cant regring Honda cranks, well technically you can but undersize shells dont exist!
Murf:
That’s strange on the first photo of the crank the journals looked very nice, now on the photos with the plastigauge they look really scoured, is it due to some strange light effects on the photo.
That apart it looks like the bearings are in spec.
Acro1985:
I think it's the camera on my phone and probably the grease I put on to hold the plastigauge in place. As when I cleaned it up afterwards the journals look really good
