Legal action? Are you kidding me. That is the last shit that you should do... A BOS doesn't really mean shit. It's not a legal document. Possibly if both signatures are notorized it will mean something, but won't change what you gotta do to get a title. To get a title you must take the bike to an inspection place, they will run the Vin to make sure it isn't stolen, double check that it looks legit to the best of their knowledge and get you a title. It doesn't even cost anywhere near 200. More like 50 bucks with plates...
