Topic: Airbox compatibility?

[vorhese]

I have a 77 CB750A ... do any of the K or F model airboxes fit?

if not i have one off a 77A.no idea what its worth.if intrested i can send you pics.i do know the air boots are a different size than the others.

mine is pretty badly cracked. I'm going to attempt to repair it but if not I will need a new one.  It will work, it just won't be purdy.

I'm going to say the airbox that came with my bike is not correct.  Marked CB750F-F   393 manifolds.  They don't fit on the mouth of the carb, even if I warm them up.
Are all years of CB750A airbox compatible?

OR

Are the carbs wrong?

LUCKY you those are round tops.i put a set on my 77 and it ran so much better.you will need an airbox from a 76 or earlier K model
