It is some sort of emissions control valve. I think it adds air to the exhaust to lean out the mixture and cause any unburnt fuel to combust. Or something like that. The TT store sells a plug kit, to seal up all of the holes when the valve and hoses are removed, for $33.95.
The WR is a total joke when 100% stock. I rode mine for 25 miles the day after I got it and could not believe how corked up it was. Now, with the free mods, JD jet kit, AIS removal kit, YZ throttle stop screw, and PMB exhaust insert the bike must make more than 3 times the power of stock. Really...it's a huge difference.
