99 WR400 question

Why is the vent line from the top of the engine run into the air box on my 99 WR400? My 05 yz450 runs down the the front of the engine and dead ends under before the shift lever.

If you stall in water and try to kick it over with the rubber hose submerged, it will suck in water.

Thanks. I guess I can vent it without going into the air box since its a supermoto bike.

factory they vent down, but someone probably ran it to the airbox...i did with mine to keep it high and dry and added a filter
