Had the same situation with a bike I bought in VA, never did understand why it has the CA emissions, evaprotive cannister and such. I did the AI removal with a kit from Brent (seamless procedure, thanks) There are some posts on the CA emissions removal in the archives. I decided to leave it for now, everything works, does not contribute to performance, is not very heavy, and it keeps unburned hydrocarbons out of the atm..... Any reason to remove it? I'm not sure....
