New (to me!) '77 CB400F - US model

Thanks Bryanj!

The rubbers connecting the carbs to the airbox should be nice and squidgy. If they're not then you may need to remove the airfilter assembly to give yourself enough space to wiggle the carbs free, this is the case on the 550f. warm them up, try lots of penetrating fluid around the rubbers (someone may chip in and not recommend this, but i find it works)
i found the 400f carbs quite tough even with good movement in the airbox rubbers, lots of easing, patience and sore hands.

The rubbers are pretty hard and "unforgiving." If by the airfilter assembly, you mean the box the filter lives in - unless I'm mistaken, it seems like removing that is a major job due to all the electrical components mounted to the left side of it.
I was able to pull the airbox-side rubbers from the carbs, but I still can't see how to gain enough room to pull the carbs away from the engine-side rubbers. Maybe some WD-40 would be safe to try - not to gain room, obviously, but to ease the movement...
I'll keep at, my hands aren't all that sore yet, so obviously I'm still not doing it quite right... ;)

I can't find it with search on here, but I thought that the more 400 experienced owners may unbolt the airbox and just move it back in the frame to allow more room.
Your hands do end up a bit scrappy doing things like this though :)
Any heat you can get into them helps with flexibility.

the carbs are not seated that far into the manifold-side rubbers, there is 'just' enough clearance to pull the carbs back, push them down and then pull out - i think the side you pull them out matters too if i recall correctly.
