Hi,

I want to know what pipeline goes into the part 22 of the airbox and what is the function of this pipeline.

Thanks

That's for the crankcase vent. It's a large black tube that will connect to the top of the engine cases.

What is your Grizz? A 350, 550, 600, 660, 700?

660

Go to the parts diagrams, look under "Crankcase", item #8.
That's the black tube that connects to the airbox cover.

Is normal to see oil from that tube?

Umm. Mine doesn't do that sooo... :|

That all depends actually. Normally, no you should not see oil coming out of that tube. But you should see an oil film, sometimes a mist of oil. That is ok and perfectly normal, especially at high rpm's.
If you overfill the crankcase with oil, then you could potentially see oil come out that tube. But you would need to really overfill it to do that. If you tip the bike on it's right side (or rolled) you could potentially see oil come from that tube as well.
If your piston rings are bad and your losing compression past the rings, then this can potentially cause oil from that tube as well.

First need to rule a few things out before assuming you have issues.
Was it overfilled with oil?
Has the bike been tipped over on it's right side (or rolled) for a period of time? If so, did you wait a couple minutes for the oil to settle back to the bottom of the crankcase before starting it once righted up again?
Have you done (or can you do) a compression test?

Yes. The bike was overfilled and what I Saw was an oil film.

Well then your most likely fine.
Drain the oil down to the proper level and ride on.

I Will do that and clean the oil to see if everything is ok. Trank you
