I think its kind of a touch and go thing with CA. Some times cops will give out fixit tickets like there is no tomorrow at certain spots where bikes are known to go and use the streets as a race track, but as far as a sound limit I don't think it will happen. We can thank all the harley guys for that. Think of how much of fuss they would make about it. They would voice their opion much louder and more then the sport bike riders would.
