Boygofast in eBay is based in Norwalk, Ca. Although I have had good luck with them, there are others that have had bad experiences with them. They usually get the engine to you with in 3-4 days in Glendale. The reason for the no shipment to California is the emission restrictions placed here. California has the toughest. None of the engines are technically legal. Even the ones with the catalytic converter and the sticker that states EPA certified are not legal. Legal i not proper term either. It's more "not permitted". But once in, then you can install, register, and ride. California is funny.
