Removing the airbox
Note: The old airbox removal article stated that you would have to break your airbox to get it out. This is not true. You should be able to remove it undamaged if you are patient and careful enough. It shouldn't be necessary to rip it into pieces in order to remove it. And make sure you don't; if you put any extra holes in the airbox, you'll let too much air in and the bike won't run right.
Removal from the rear
This is the preferred method, but it hasn't been fully documented. You'll be on your own a little bit, but with a good amount of patience you should be able to figure it out.
Remove the rear wheel, both rear under-fender pieces, and the side fairings. Take out the battery, then the two bolts under the battery that hold the back of the box to the frame. You then have to remove the following items:
Removal from the side
To get started, you need to remove a lot of pieces from the bike. Follow the directions for removing the carbs, including removing the carbs.
Remove the two bolts at the inside front of the rear fender and pull the fender back a bit. Remove the battery, then the two bolts that hold the back of the box to the frame under the battery. Then remove the 10 screws that hold the two halves of the box together. When you've got them all out, you should be able to break the two halves apart. If you have trouble doing this, then you missed a screw; they're hidden all over the perimeter of the box.
Remove the plastics and filter element from inside the box at this time. Slide one side of the airbox forward and one side back. Work the left half of the box out of the frame, then the right. Be very patient.
If you are removing the airbox to make it easier to remove your carbs and work on them, you have two choices: You can do the battery box mod to make it easier to remove the carbs while keeping things close to stock, or you can add air filter pods. Of these two, we recommend modifying the stock battery box and putting the airbox back in.
If you leave the airbox out and add pods, removing the carbs is as easy as loosening a few intake screws and popping them out. This is good, because removing the airbox is going to force you to remove the carbs pretty often in order to get the jetting right. If you're a new rider, it is not recommended that you mess with the intake system. Go out and ride.
If you do the battery box mod, then you'll be using the stock airbox and the carbs will still be simple to remove. Pods are much more fiddly than the stock arrangement, and they're also louder. If you want a bike to ride, rather than one to work on, you should really avoid going to pods.
One other thing you may want to consider at this time is putting hose clamps on the air box boots where they connect to the carburetors. The stock springs have only 2 modes - easy and PITA.
