what is it for...where does it go?

[Cosmo]

Next to the crankcase vent hose is a small diameter hose. It is not plugged into anything and seems to have no effect on the way my 79xs runs. Also can I just remove the emergency shutoff switch or will it effect the electrical system?...Cosmo

[Snow]

Is the smaller hose possibly connected to your battery or gas tank? It might be overrun drainage - does it run between the swingarm and main frame?

Yes, IIRC you simply remove the tip over switch and throw it away.

[Cosmo]

No it is not the overflow hose. Is connected on one end to the motor to a connection in the center of the crankcase just below the breather hose...Cosmo

[Snow]

Do you know where the other end is connected or is it not connected to anything? I'd have to take a look to refresh my memory... I know there's a engine to frame ground strap in that area and of course starter cabling...can't think of anything else though

The straight skinny on the skinny hose

It is the middle drive vent hose. It terminates under the seat where the front mounting bolt for the airbox is bolted to the frame. There should be a flat metal bracket with a small depression in it that the hose fits into. It must be vented to atmosphere. I have a pic of the bracket and location, but it is in my other computer, and it crashed. It can be tied off to the frame rail, but should be attached some where that rain and other road grime won't enter the hose and contaminate the gear oil in the mid dirve.
