ang on, depending on the serial no on em, will determine wether they`re off a 750-900
from the haynes manual:
CB750K(Z) - VB42A / VB42C primary main jet 68, secondary jet 102
CB750K ltd - VB42A primary main jet 68, secondary jet 102
CB750F - VB42B primary main jet 68, secondary jet (pre 1980) 98, (1980>)100

CB900F - VB51A primary main jet 68, secondary jet 98

But i`m sure theres another No on the carbs too, likewise the crankcases are stamped RC-0********* or SC-0******** for 750/900
