Dual mukuni 44's fuel line pressure?

[ss2rambo]

I have dual 44mm carbs on my blaster. does anyone know the fuel pressure should be between the fuel filter and carb. The diaphragms on mine can be weak and would like to know if they really are or not.

do you actually have a guage to measure the pressure? I think it should be about 2 psi at idle and 4 psi at WOT.
