Motorcycle Repair: 1982 750sc Nighthawk carb upgrade.., cb750, bill silver

Question
Hi, I have purchased a 1982 CB750SC Nighthawk with one of the carbs cracked, because someone tried to extract one of the jets and broke off the whole piece. Will any other year or model or size carburetors fit my bike.
I have searched all around and no one seems to be sure. You're my last chance.
I have found some from a 1995 Nighthawk, some from 1986 Nighthawk CB700sc-g, some from 1979 CB750F Supersport, 1991 CB750, and 1993 CB750.
Anything will help.

Thank You.

Andre.

Answer
Andre, the 1982-3 CB750 was the last of the DOHC 4 valve motors, which used shim adjustment for the valves instead of the later hydraulic valve train designs.

Basically, any carburetors from the 1979-83 CB750 series... SC, K or F models will fit that motor, but the jetting may have to be adjusted for your application.
