Help! Transalp 650 fuel tank breather
 

Can anyone tell me what the fuel tank breather on a Transalp is supposed to connect to? Obviously one end connects to the fuel tank, but the other end has a jubilee clip on it so it looks like it should connect to something? I assumed it would be the airbox but I can't find anywhere to connect it to, so at the moment it's just loose under the seat... Thanks!
