Thank you!, well that hose goes inside a pipe along a clear hose, and I have no clue where it leads to lolWelcome to the site
That's your gearbox vent hose nipple.
Should be a few feet of an oil/vapor-approved hose run to somewhere outta sight and clear of any water or mud mingling. I'll try to remember to take a look at my bike and see where it routes to.
You could do worse than to change your gear oil out, not knowing how long that's been open to the elements, you could've got some muck in there at some point.
