Blacktop04,
I am not going to pretend that I am a gearhead, but I do not believe you should be getting oil in the airbox at all.
On my 1200, I have three small diameter hoses that hang down just about where the center stand would be, if I had one. I know that one is for the battery, another is for the gas tank if it overflows. I am not sure about the last, but I think it is a vacume hose for my four carbs. Or maybe it is for the crankcase. Whatever it is for, maybe you are missing a hose and therefore, what should be directed to the ground is instead being sucked into the airbox. I wish I could be more helpful, but like I said, I am not completely conversant with the engine department
Good luck.
