I too use vinegar as it is a mild acid, but I follow it up with a baking soda solution as a neutralizer. Being that this bike is 28 years old, I think that you should be prepared to replace alot of rubber components. Unless the slides have been replaced, I'd "almost" bet you that they will have cracks in the diaphragms. Also be sure to pull up the rubber boot and inspect the formed rubber hoses coming off both the front and rear of the intake manifolds. Check those hoses at their bends for soft spots, they'll suck holes in them at that point. The other items that I'd automatically change if they haven't been would be the insulators. All of these rubber items get hard and brittle over time and won't seal very well at all, causing vacuum leaks and lean running conditions. The last thing that you want is to have to pull the carbs a second time, so be through and do it right the first time. Plus you can't adjust the jets or sync. the carbs if the system is not sealed tight'
If the recall has been done, just a good "through" cleaning and rebuilding with new wear items should do the trick.
Look at Partzilla's website under your year and model, then look under "cylinder head" to find the hoses etc... Good Luck!
