You measure them with a "U tube", I think it's a Yamaha part, you see where the fuel is on it and hold it against the carb body.
Does the bike run badly ? it could be a gasket leaking rather than the float height.

Going from previous posts; BDST32 carbs.
The nearest settings I have are for the 1WG Genesis utilising same units.
Hopefully the engine and carb settings are similar and also the engine/carb angle.
The bike needs to be upright not on the sidestand.

.
This is the fuel level NOT the float height.
Others may have that info.
The tube can be made from clear hose with suitable heights marked.
EDIT: 13mm seems to be the base setting for the actual float height.

What would symtoms of incorrect float hight? Would bogging down at slight throttle be a symptom

It sounds like over fueling or pinholed diaphrams. There are various ways the carbs can over fuel not just high fuel level.
I've said this before - take it to a dyno and get it set up properly.
