HI, Does anyone have or know of an airbox for my 1977 cb750 f2.

The 77/78 K and F box I think should fit your bike. Most of us here use our boxes so you might be better off checking a boneyard in your area or ebay if nothing else. They are pretty durable except for when some person gets over ambitious and tightens the bolts holding the box together and strips out the bottom hole.
Then you need to weld a nut onto the bottom of the bolt. Mine is like that.

Many thanks for your reply. I tried a breaker here but no joy yet. The engine is from a K3 1974 from what Honda say but cant find much more infromation. I will kep looking.

Many thanks again

Ah then you want a 71-76 airbox then. See, the rubbers are smaller on the 69-76 airboxes since the carb openings are smaller. Unless of course, the carbs you are using are the later carbs with the accelerator pump. Then you still want the 77/78 airboxes. BUT, the A model box will not fit.

 I have the carbs with the accelarator pump an although tight it fits fine. So i neeed the 77/78 well thats more info for me many thanks for that. Its hard to find out anything at the moment but just away to make a list on my white board then get stuck in.  I havent started her for 8 years but all the connections are sorted I just need the new plugs and she will fire up. Its a bit of a mix and match but I will be taking time over the restoration so in no hurry and will keep an eye out for bits and bobs.

Many thanks again
