For the OP,
remove the trumpets from airbox, fit them to carbs then, sync carbs.
You will have to re-jet for pods or bellmouth's.
If you don't want to spend a lot of time messing with it, use stock airbox.
So jetting for open exhaust is fine, but not for open intakes (pods)? I don't get it.
Thats exactly right, you don't get it....
Yep, jetting for open exhaust is much easier than jetting for pods
