I take the one bolt out as mentioned (By your left knee if sitting on sled) Then I split the box apart (7 screws I think). This makes it easier to remove the whole airbox. Once its off, disconect TORS, TPS (at the chaincase side) and your fuel lines, throttle cable and choke cable.When removing the cables just loosed your jam nut and that way you won't change any settings. When you have the carbs back on and are ready to install the air box, take the big piece with the carb boots on it and install it. If you leave the cone looking thing out, you can reach from the inside of the airbox to push the carb boots over the mouth of the carbs.. makes it a lot easier. Put the cone thing back in and then the top piece.
