BTW, lemon juice carb soaking will turn the carbs dark too.

The only thing I have found to work getting the dark charcoal grey/black off, is giving them to somebody with a "real" soda blast set up and pay the invoice.

I plan on picking up a sonic cleaner this year and doing my 2 sets of carbs...... read this a few times or more now and shudder when I did ....thank you and if we ever run into each other I owe you a buck or at least a beer.
CLR sounds good not 100% on what is the best yet but we know what not to use...... since its only for 25 min at a time its gotta be some thing potent but not too much...... Zukdave likes simple green if I remember.

Simple Green Pro formula would be a safe choice. The regular Simple Green is corrosive so I'd be careful of that stuff too.

Pretty sure the OEM Mikuni and Keihin carb bodies are zinc. Not sure about the TK's as used on some 550's though.

Straight up Pinesol is what to use. Not Pinesol AND water. Never had an issue with 100% Pinesol. Now, like others said, you probably need to soda blast or scrub with some other cleaner. Might be superficial, try hitting them with wd40 and a wire brush.
