Best of luck with the restoration project. I'd suggest you a cool paint job for the bike, I'll have to look for the pic.
As far the carbs are concerned, FZRs have the most complex of carbs among sport bikes as per my little information. It would be a lot better to go for new carbs if available.
P.S. I would feel myelf so lucky if I were half as good at mechanic as you are. Every owner of such a bike should know the mechanical work too. Keep the good work going!
