The answer is NO. On my sx, i have removed the airbox by removing the secondary clutch and then removing the carbs. if you lift up the gas tank couling (directly over airbox) just a bit, it is enough to get in there with a wrench to loosen the top airbox mount.
Then have a buddy apply light pressure to the couling pulling upwards and you should be able to remove the airbox out over the jackshaft. Also just make sure you have all the airbox bolts removed. there is one by the brake disk that you dont want to forget.
Not a fun project by any means. I too give an F.
