Welcome to the forum, here in AZ the law makers and environmental's were trying to get MB's banned. The environmentals used the aurgument that the 2-stroke were dirty. Roland at spookytooth proved them wrong by taking he's MB's to the emmision testing and passing! Well, they left us alone after that. As far as CA laws, I dont think anybody really knows. There is so many laws on the book nobody can figure them out.
