Where does the engine case vent line exit from the factory. Does the line drop down behind the swing arm pivot shaft and tie together with the rear shock hose? What about the carb vents? Same? A pic would be wonderful

Carb vent lines route down between the case and swingarm. The case vent should route up to the airbox.

Which KDX model are you asking about? Crankcase vent hose for 1986 - 2006 are up to the airbox for KDX200 / KDX220R.

84 kdx. I do see a hole in the back of the airbox

It may go there, then. Thanks for letting us know.
