Hose at bottom of airbox?

[Boriqua]

I have a nipple at the bottom of my airbox. I have since plugged it but looking on ebay for some other parts I ran across an airbox and there is indeed a hose attached. The airbox is after the airfilter so where does that hose go and what does it do?

It's a drain hose and it hangs down at the back of the engine.

But wouldnt that allow unfiltered air to be sucked into the carbs?

The factory hose has a make shift one way valve.unplug yours and just put a hose on it . It can not draw enough unfiltered air to make a difference. If you get water or your carbs flood it can drain with it plugged it is going into you motor

No. The hose is on the "dirty" side of the airbox, before the air filter.

Uh no, it is after the filter, under the air box, not the filter box. I got a new one for my bike, it came with just a simple plug, where as my old one had a piece of foam filter in it.
