Carb cleaner may be aggressive, but I don't think that it can remove chrome.

There was a craze for fitting lighter wrist pins some years ago and many claims were made about the results, however some of the wrist pins had a habit of breaking.

Nowadays you can get the same result by fitting lightweight pistons, but without the breakages!

I would suggest that you review what you have got
R90s 1070 replica, R90/6, 1958 R50
1971 Commando Fastback
