Thats a bummer. I am curious how the surface finish will be after reverse chroming. Deffo a specialist job.

I suspect they are polished and not chromed. But hard to tell from the picture. Carb metal doesn't chrome easy and is rather expensive.

Unfortunately only two of five are any good...

The replica's Italian Mold lab look good. They are stainless and €300 a set (begin 2023)....

I have 5 "fork ears" for the 500 and all are dented in the same way at the back.

Very good experience with Motobatt also. Over 4 years in use without any issue. Cold storage during winter with trickle charger attached.

Removing the chromed crimp ring isn't that difficult.

Recrimping is a pain in the rear if you don't have the right tooling.

As a complete novice to painting with a spray gun i had a very promising result on some test pieces with the method and materials you described.

- need a bigger compressor (size does matter here)
- need to disassemble front and rear hub because already with spokes and rims

It will be more expensive
It will  be more laborious

Thank you very much for posting!!!! ;)

Thanks guys, that helps a lot.
Regarding the spoke nipples i know that early CB750K2 had zinc plated and yellow passivate whilst later ones were blue passivated.

Misc / Open / General part number decipher

Already trying all evening to find a post where part number code's for general parts are explained. How can one tell if a hex bolt is chromed or zinc plated from the part number?
General part numbers have this format:
xxxxx-xxxxx-yy

I am interested in the YY designation. I've seen 4J, OA, OB, O2, O7 etc. I am assuming that OB means chromed. Is that correct? And does this also apply on nuts and washers?

Cheers.
