So I got a 2003 Nevada plated WR 450 last week. I Took it to California highway patrol today to have a friend of mine do the inspection on it. I went from there to DMV to register it. They informed me that the computer would not let them register it street legal because it is not California smog complient. They said there is a number in the vin that designates it as non compliant. They were very helpful and said that the only thing they could think of, would be if it had a California smog complient sticker on they could send it in for an override and hope for the best. Though they said they have never seen it done. I told them to hold off while I decide what I want to do. I've known people to plate these in CA but I'm guessing that they are green sticker years. Does anybody know what years were green and which were red? I thought about swapping out the frame, or try to register it in Nevada.
