New member. Hope this isn't off-topic or already beaten tio death: My son is about to buy an 2003 ZX636 from a guy in Oregon, and he's hearing conflicting info about whether it is (emissions) legal to register in California. He hasn't seen the bike yet so he'll TRY to check the emissions sticker if it's there and he can find it. Bike has only 13k miles and getting it for $3500. Thanks, guys.
