It really depends on how much work one plans to do on the carbs. I've owned my KZ650-C1 for a bit more than 40 years. During that time I have removed the carbs twice. Once was to clean them after I screwed up and let them sit with fuel in them for a little more than a year and once to replace leaking carb holders. Removing and reinstalling the carbs is a bit of a pain, but not really a major undertaking. However, to simply clean dirty float valves or other fairly straightforward tasks I would not remove the carbs. This is because removing the carb bowls with the carbs still mounted on the engine takes very little time or effort to do, and many tasks can then be performed. If a task can be performed by simply removing the carb bowls for access there's no need to remove the fuel tank, fiddle with the throttle cables, unhook and remove the airbox boots, loosen the airbox brackets, etc., etc. In the time it would take to remove the carbs from the engine and sit them on the bench I could clean a couple dirty float valves and be out riding the bike.
