Does it meet Californias CARB requirements?
A It will meet California Air Resources Board (CARB) standards for homebuilt motorcycles. Three-wheelers (of under 1500 pounds) are classified as motorcycles in California. If it does not meet local emissions standards, you are entitled to a one-time-only exemption from motorcycle emissions standards for a homebuilt or customized motorcycle. If your state classifies the XR3 Hybrid as a passenger car, then you can install a catalytic converter and particulate trap. Since ultra-low sulfur diesel fuel was introduced at the end of 2006 (in the U.S.), catalytic converters will work on diesel engines.
