How tight are your clearances? I have a set of bearings, king coated that show them exact same lines and they were on a K1 crank. In my case they were just a bit on the tight side. I did not re use them. Can take pics if it would help.
Clearances are .0025". My machinist is very good. I double checked it with Plastigage on assembly, was right on the money.
Pics would be great if you can, thanks. I'd like to see for my own edification as I'm sure others might too. I'd rather not get new main bearings if there's no need.
