Has the bike been desmogged? If not, there's a good chance you might have a hose off or cracked. Get an inspection mirror and look behind the carbs, you'll see some hoses about the size of windshield washer hose. If one is off, it will be obvious. If cracked, may take some time to pin down which one.
Along with the above, I'd consider running some Techron through the gas. Dump the whole bottle in along with just a couple gallons of gas, run until you're certain the mixture is now in the carb bowls, then shut it off and let it sit overnight. Next day, take it out and run it at low rpm for extended periods.
PS: don't need the badges in any case.
