The 1" holes I drilled in the air box for the snap in vents are not visible at all. The side of the air box on the exhaust side of the bike isn't really the air box. It is a false panel riveted on to the outside of the airbox with a 1" or so gap between it and the airbox. It is there just for looks and to make a smooth line for the side panel. I drilled those rivets out and put 4 out of the 6 vents there, and up high so water would have a hard time entering the air box in the event of a good splashing. I screwed the false panel back on instead of rivets so I could reach the vents easily to pop them out and clean them. The 5th vent is right in the front of the air box up high behind the shock blatter. The 6th is on the back of the air box up high on the coolant bottle side. You can see this one if you look into the hole I cut out in the side panel.

I was careful to leave all the corners and beefed up sections when I made the hole. The box is constructed of very heavy plastic. I feel the integrity is still good but only time will tell. The box has extra heavy corners and beef where it bolts to the rear subframe. I am confident it will hold up. I was more concerned about the weight of the battery and if those cuts would weaken the tray. The tray remains very sturdy. I will let everybody know how it hold ups over the whole summer.

I just went out and pulled my seat off to try and see what you did. The air box is pretty beafy back there. You should be alright if you were as carefull as you said about keepng the strength points in tact.
Like you said though, only time will tell. keep us posted. Obviuosly I have nothing better to do than sit and wait, hehe
