As I remember they were not sold in California because of the gas tank, venting I think. But you could bring them in used. They are old bikes now and I don't think they care.
there were bikes out there that had CA emissions on them. they drew .5 amps when running and could cause the bike to vapor lock if allowed to sit in the hot sun. there was 1/2 an hour dedicated at training on how to identify and remove CA emissions. only in CA would something be mandated that would cause your scoot to not run and then die when it does.
