New (to me!) '77 CB400F - US model
Nurse Julie:
I find it easiest to remove the air filter, undo the big clamp on the air duct guide, remove air duct guide by pushing the guide back into where the air filter was. Loosen all clamps.Pull back on cleaner chamber, this will remove the rubbers attached to the air chamber from the carbs. Then remove the cleaner chamber completely from the off side of the bike. The carbs then pull out of the carb insulators. Remove complete carb bank from off side of bike. Reverse to refit.

This is the approach I'm trying - but I can't seem to get the air duct guide to budge. Nothing seems to move in there, and it all feels like hard plastic rather than rubber. I'll investigate further...
Nurse Julie:
It's just the metal tube that links the two that you need to push through. It can be a bit tight. Have you undone the really big clamp holding the rubber around it ?

I was going to write: Yes - all clamps are loosened, the big one removed completely. I think my main problem is that the rubber bits are hardened up - I'll try to warm them up and maybe give them a massage. Oh boy, please don't tell my wife about this!
But now I see your very helpful photo - the rubber that holds the air duct guide feels almost like the plastic of the air chamber, so I expect resistance. But I'll do my best to work the guide backwards out of the rubber seal.
Part of my problem was, the parts diagram make is look like the air duct guide goes between the rubber seal and the air chamber - rather than the air filter cavity side, which your photo clearly shows. Do you ever use any kind of lubricant to help ease parts along old rubber?
