Its routed down the side of the bike to drain anything out that might get in I guess. Have not re connected yet but why is the sound intermittent??
Oh! i have ectomy'd all the SAS and such
I'd say you are having an intermittent air leak in your air box. Alongwith the weird throaty noises, do you also have un-steady idle and running issues ?
The drain tube should be attached to the air box, but disconnecting will not cause any noises/issues. Why not re-connect it and see if it changes anything (ideally, it should not) ?
