I am wanting to remove the airbox from a Mk3. The top bolt is an easy remove, but the bottom 2 bolts and actually pulling the airbox out look like a problem.

What say the hands on mechanic here please?

Is there an article on converting to an earlier Norton style airbox?

Or is the change a "bolt-in"?

Okay, thanks, I see the earlier removal words from ausnorton -

Hello ,
I know its a bit late but for anyone else out there this is how I got my airbox out yesterday.
Remove carbs and manifold ,
Remove starter motor,
Remove oil tank bolts ( you may not need to actually do this but I did anyway for a bit more wiggle room ),
Remove the cylinder head oil feed line support bolt / spring , ( not banjo fitting )
Remove airbox bolts / nuts ,
Rotate the bottom intake side up , and then rotate to the right as if you are trying to push it out the right side as much as it will go , keeping the engine earth lead and head oil feed lines clear ,
Then bring it back out the left side / timing side , and voila , Its out .
Its very tight and requires finessing but I didn't need to be too brutal about it , and no need to cut tabs or remove battery tray .
Now to fit the Mikuni carb :D
Cheers
Bal

See Peter Joe's post in the previous link regarding the lower mountings.

A new LH side panel upper mounting bracket will either have to be fabricated (or bought) as the standard bracket is attached to the airbox.
 
Old Britts Z bracket looks like a nice solution for missing dzus.

If it has the riveted top bracket than the above will not work, the MK2A airbox has captive nuts so the bracket can be removed - why the backwards move for the MK3 is anyones guess.
