Honda CB400four crank/conrod color bearing game
« on: November 11, 2021, 07:12:16 PM »
Dear All, I would like your knowledge and advice on which color codes bearings these are:

And this is a different set of crankcases, than the rollerbearing marks (see other post)

Crankcase stamping BBCBB
Crank A1 B1 B2 B2 2
Conrods 2 3 2 1

So that makes for the crank: B1 B1 C2 B2 B2
Green Green xxxx Brown Brown, what is C2 crank?

Conrods: A2 B3 B2 B1
Yellow Brown, B2 and B1 are?

Please add and confirm the color

Thank you a lot

Kind regards,

Emiel
