Louis, here is an illustration to use...

The top vent hose goes down the back side of the cylinder head and cylinders, through the notch in the transmission cover and turns to lie with the end towards the small drain hole in the top case.

The two vent hoses for the intake valve guides can go together in the Y fitting and the hose can just hang down. There is a small fitting on one of the air filters that was used for that connection, but it isn't critical, as it is not a vacuum hose.

There are NO carburetor float bowl drain hoses on these bikes.

I have restoration guides for these bikes on CD.
