Little black box?

What is the black plastic box located on the right side of the carb. just above the header/mid-pipe junction with the two hoses running into it? It appears to be a crankcase breather apparatus of some kind, can it be safely removed? My yz250f just vents to the atmosphere. It sure would open up the area around the carb. for easier access.

Your guess is correct. No, it should not be removed. All 4 stroles have a vapor separator of some kind some place. Suzuki just puts it external.

If you pull it you end up with a big mess, many have tried and many have had to put it back on.

Warnings well taken guys! Thanks
