It is possible that there is a california version. I had an 04' VTX 1800 that was california emission,(evap. can and extra emisson crap), you could tell by a designation in the vin number but, I don't remember exactly what it was,(CA I think). They typically dynoed a little less than the 48 state versions. Good thing is all that stuff is removable without harm, just have to plug the vaccum ports where it comes off.
