The original airbox isn't bad by any means and yours might not be affected by this issue, but the adapter boot on my SSR was slightly deformed and sometimes came detached from the box, where a long spring was used to compress the adapter on the airbox opening.
Being paranoid this would happen during a dusty ride, I removed the airbox and replaced with a standard UNI pod filter: it breathes a little better and is very easy to service. Servicing or tuning the carburetor is a bit easier as well. A trade-off to consider if doing this: the filter loses some shielding and protection from the elements.
If your airbox seals nicely to the carb, you might simply drill some 1/2" holes on the top of the airbox to help the bike breathe a little better. However, you can do nothing to this bike and find that it is great without any mods.
