emission

Does anyone know if a 2009 FE 570 is emissions legal in California? I'm not sure if there's a difference between on/off road vehicles out there. For conversations sake let's say it's bone stock.

I got a 2011 FE 570 S and it has the emission thing hanging out the side of the cylinder. Has anyone put the plug (that comes with the bike) in. And does it improve the performance or change it? Thanks Also I found an article about the Dirt rider guys doing it, here is the link...
