1991 750

I have a question about a hose i can't identify. If anyone has the manuel, it is on page 4-10 under "Engine Top End" the bottom right picture is reinstalling the cylinder head cover. On my bike the front cylinder has a small (maybe 1/2" diamiter x 4" long) hose that comes out the front. I looks just like the hose in that picture in the manuel exept mine is all squashed and points down. I have been trying to figure out what that hose's purpose is?

I believe the one your talking about goes to the engine vent, if its the one that hangs down in the front right by the oil filter that is a drain for the air box. Sorry don't have a book, just going from memory.

either the drain for the airbox (which drops down infront of the engine), or the breather, which goes from front cylinder to the bottom of the air box

The drain hose is approx. 1/4" diameter, the crankcase vent is the larger, shorter one. The crank vent should be connected to the airbox or have a filter on it. I wouldn't leave it open.
