yea you have to be carefull. I bought the service manual for that stuff and suggest that you do as well.
the air box will not come out that way. to remove the air box you have to remove the rear fender, jack the bike up a bit, detach the shocks then jack it way up allowing the swing arm to come down. you can then pull the air box out through the back.
you should be able to remove the plastic gromets thay hold the fuse box inplace and lean it forward.
