I've seen a good many postings warning folks to re-route the valve / cam cover vent hose to the aribox preventing the rider from sucking water into the engine if stalled and restarted in higher water.

This was one of the last mods to be done to my 06 WR450.
Am I missing something or is it already routed to the airbox from the factory?

I'm assuming the vent hose and AIS on the 05 and later is what made the grade for CA green sticker.

Anyone know why the WR 250F didn't get green sticker status?
