Hello Rod,
My apologises for not replying earlier I didn’t have a look at the forums yesterday. There are two hoses exiting in this location one is a breather for both carburettors and the other is a breather for the fuel tank,
it has a non return valve in-line near the carbies.
I only cut enough of both hoses so they were not hanging down were water may affect them, the only issue with cutting them to high up is you may get a bit of fuel on your bike instead of dripping on the road.
I also had the angled opening of the hoses facing backwards as I assume the water was coming of the front wheel. The reasoning behind cutting the hoses at an acute angle was to create a greater suface area of opening for the breathers
