The tube coming down to the ground comes from a small tank (smaller than a fist) under the airbox and behind the battery. The tank collects fluids from both the airbox and the crankcase. You should see two tubes up from the tank- one to the airbox, one to the lower backside of the crankcase (not from the valve covers).
But... Check to be sure that it isn't the overflow from the battery. - James O'Gorman On Jan 11, 2011, at 9:23 PM, Dustin Mcclure <[email protected]> wrote: > Hmmm...I actually did not see a tube going from the airbox to the > valve cover...I should probably look into this.
