Just curious, but in CA do you need to submit your bike for annual checks to make sure that your gasses aren't too noxious (well your bikes gasses at any rate

)? Here in the UK once a car/bike is 3 years old it needs an annual MOT test which, amongst other things, checks the emissions to ensure you're up to standard. Personally I couldn't be arsed to put on / take off once a year.
