Could be that your crankcase breather valve is bad and letting oil get
by up into the airbox.  I just replaced mine a few months ago.  Before,
oil was constantly draining out of the airbox overflow tube--now, my
garage floor stays clean again.  I never really noticed that it spewed
more at a particular fill level, though.  It just blew by constantly.

The old breather valve (don't know what year your ST is) was just
plastic (white or tan colored on my bike) and the new, redesigned piece
has a reinforced, metal insert and shaft in it and is black.  If you
have your left side fairing off, it's pretty easy to check, just 5 or 6
bolts to remove the cover that is connected to the airbox by a rubber
tube.

Laters,
Brian
