Take a closer look. The hole in that stub is blind (or should be). It doesn't go anywhere, and nothing belongs in it.

If the hole is open make sure you block it off immediately.

If it is open you are sucking unfiltered air into your engine.

If it is open the reason is probably because the PO did a crankcase breather modification (Yamaha make a kit) - see a recent post on this forum that had pictures of this kit fitted.
