Are the carbs the stock Keihin CV34s ? If so then you can stop looking as the seats dont come out / cant be replaced. They can be cleaned up with carb cleaner on the end of a Q tip.

If they are damaged then you might have to look for a set of replacement carbs.

Hopefully the Q tip trick will work.

I've had pretty good luck using some mothers mag polish on the end of a Q-tip to polish up brass carb seats. Makes them look like new.

What's the actual problem ? Scratched ? Chewed up ? Leaking?

Maybe time for steel wool + mothers

Probably a dumb question on my part but you did try new float needles ?

Many times when the Keihin float needles won't seat and leak, the problem is the needles should be replaced. While polishing the seats makes them look nice, it doesn't do much for sealing. As long as there is nothing on the edge of the hole in the seat; whether they are shiny or not doesn't make a difference but it doesn't hurt to clean the seats. The correct float needles for a Keihin CV34 have rubber tips and a small piece of wire that hooks over the tang on the float, I think. I would also check float levels and ensure the vents are unobstructed.
