Normal, they are the drains from the air box, the crankcase vent is directed back into the air box and will have oil vapour in it, some is drawn back into the engine and burnt and some collects in the air box, mix it with water draw in from the air and you get that oil water mix.In you case the pipes which direct down below the engine through a small one way filter seems to be missing. If all was intact you would never have seen it.
There are two drain holes on the air box if you look in under the carbs you will seem them that generally attach to a T piece. That pipe is propably the one that directs it down under the engine.
Left side is usually worse due to have the bike on the side stand and all the liquid drains to that side.
