Engine replacement

[Robotech]

Hi guys could do with some help anyone out there have a 125 varadero XL 2009 as did an engine replacement and after fitting engine I had a small rubber tube that become two tubes at the top they are breathers as it ends at bottom of frame on left hand side.  Now I know one of the two tubes go to the breather on the petrol tank but we're the heck does the other one go.  Haynes manual is no good as it doesn't really show much so please please any ideas.

Hello, in many motorcycles the petrol vents end in "Y", so that if the motorcycle falls and overturns, the "down" vent is in a "higher" position of the tank, the petrol drains from the opposite side !
in most of the motorbike, this tube ends "not connected to anything" under the saddle towards the tail of the motorbike.
I think it is the same for your bike too !!

As above... It's unlikely that fuel will ever leak out of the tube during normal circumstances, just make sure the open end is nowhere near the exhaust - just in case.
