The DD two stroke guys refer to the air box drains as " slobber tubes " , used to drain off excess fuel , etc at low rpm . These route into a catch can on the '86. We have checks that close off at about 3 psi so once the rpm rises the air box is sealed . The convoluted metal tubes that come down on either side of the bell housing are from the breathers on the valve covers . The breathers will vent oil overage . I went to larger diameter reinforced hose for the breathers , run into a 5 gallon pail (with lid ) with a couple of K&N filters . Very little oil ends up in the pail , probably overkill but I wanted the engine to breathe freely .
