Topic: 1977 Honda CB750F Airbox

[Overill]

So, my airbox on my 77 CBF750 is destroyed from fire.  I'm having trouble finding a replacement, and I'd like to not use cones.  What years, and what models would fit my bike??  I see some on ebay...but some look different then mine, but they say fit A F K models...please help  :-)

Any Honda dealer website has a part# by model/year lookup.

 The F's have bigger carb inlets so Most K airboxes have smaller openings. 77/78 K airboxes may match, I think 75/76 may fit but I'm not positive.

F/F1 also have the smaller openings

The 77 and 78, both K and F used the same filter housing p/n's from Honda.

Plenty available on ebay.
You'll want new stacks.
Also check on the for sale section of the forum.  They are often included in bikes being parted out.
