That said, bike carbs are way simpler than on cars.

The problem here is multiple carbs.

My personal favorite is the carb setup on a Suzuki Intruder 1400. One down draft and one side draft. The idle speed is linked together with a cable. No vacuum nipples to put your guages on, but that's ok the guages won't help anyway.

Or I could ride my nightster with it's EFI.
