Can anyone explain to me the best way to remove the air box...i have it loose from all the carbs but can't see to get it out to...to much stuff packed into a small area....i am having the bike painted and the painter is also going to buff out all my plastics and thus is where the problem lies since i can't see to remove it....if you have any suggestions it would be much appreciated thanks!

I believe you will have to tilt the engine forward. Follow instructions in the shop manual.

I've removed airbox's without tilting the engine but it mangles them. After removal they always popped back into shape. That was years ago. As brittle as plastic gets with age I don't think I would try it now. And to replace the airbox you definitely have to tilt the engine. The CBX is one of the easiest motorcycles to remove the engine because you don't have to lift it over frame rails. If you unbolt enough stuff, the engine just drops out

. When I've done it by myself, I'd fabricate a wood stand to hold the engine at bike height and when it was all unbolted I'd just lift the bike off the engine.

I've used ratchet straps to gently lower the engine, and lift it back into place.

It helps if you have a Hondaline engine guard. Place the hooks on the center portion of the guard and the strap over the frame. Or, just put the hooks in the lugs on the front of the case.

It's helpful to put a strap from the centerstand to the front wheel too. This keeps the bike from rolling forward off the stand. Of course, a front wheel chock is best.

The whole process is a bit intimidating the first time you do it, but really isn't as bad as you might imagine.

yah this plastic is definatley brittle...i have done enought damage trying to muscle it out...the best option will probably be to lower the engine...if i didn't want to clean up the carbs and stuff i probably would just leave it in but since this is also on the list of things to do i guess i will just suck it up and get it done...looks like a got a busy night after work...thanks all for your help i will be letting you tomorrow how it goes

I removed the airbox on my '79 last week without tilting the engine. It took heat from a hair dryer to make the rubber boot semi-plyable and WD-40 as a lubricant.
As George mentioned, the rubber distorts but does return to shape. Taking off the metal bracket from the top of the airbox is finicky but it provides a bit more clearance.
