I wouldn't be too scared of taking them off the rack becasue of the fuel connectors. You just have to unscrew and slide all four off the rack together. The scary part is getting all the connectors, tubes, choke linkages, and the spring... all engaged properly on reassembly as all four have to go back in together. This is a pretty good trick. You may break a fuel connector if you get cute and try to manoeuvre a single one around to, say, get a misaligned choke linkage together.
You don't really gain much by having the four bodies separated unless you need to do a dip in serious carb stripper/cleaner, or have a fuel leak from one of those fuel connectors. The chokes aren't made to be disassembled - although they can be. The throttle linkages are maybe best left together, there's rather a lot of fiddly little pieces involved and they usually don't need much attention. The main throttle actuating system - the bellcranks and cable wheel stuff - is pinned together and is truly a bugger to take apart.
If you plan on polishing or replating all the pieces or some similar project, go ahead. If you want to revive a gummed up carb rack I would try and leave the rack together. If you have to resort to Berryman's or similar then it has to come apart as the chemical will eat the plastic fuel connectors and vent connectors, plus the fuel ones have O-rings that might dissolve. You will have to remove the choke plates to take out the mounting rods as there is a plastic washer thingy and a felt washer or two to be removed. The throttle rods also have these parts if I recall correctly. You can get tiny fuel proof hose to replace the (fossilized by now) vent connectors at hobby shops dealing in planes/cars/boats with internal combustion engines... but it all seems to be in neon flourescent colours. The Honda gasket kit has every O-ring in the carb plus the bowl and slide link cover gasket. The felt seals are not available, remove them very carefully and wash them out with acetone. The can be reinstalled successfully if you are gentle when working with them, soak them in acetone then gently press between a few sheets of paper towel, repeat a few times until whitish.
The exploded diagram in the Honda shop manual is pretty damn good for reassembly but TAKE A BUNCH OF PICTURES anyway. The choke lever is pretty complex. The way the throttle linkages fit together is tricky.
Have four bins with lids - disposable food saver tubs are excellent - and keep all the parts for each individual carb in one, plus an extra for other parts not attributable to any one carb. Watch out if you pull the choke lever off, there's a tiny ball and spring that give it the click closed feel.
Have fun!
