CA and 49 State model differences on the VTX 1800C

With Riley's site closing I spoke with him and he is allowing me to repost his info as a way to archive the info and keep it from disappearing off the net. Many thanks to him for always offering this info to us VTX riders and many thanks to the people who helped compile this info in the first place.
