rogerc,
I"ve rode Baja several times......with friends who new the trails. There's way to many things that can go way wrong down there....very wrong. You cross farmers land, run in's with the local cops....or supposed to be cops...and a host of different issue...Barbed wire fences, roaming aminals and other nasty things that can make riding a nightmare.
Gas can be a problem with 2 strokes. Security of your bikes at night or during the day can also be a problem.
Don't get me wrong, it is a great place to ride...but if I was going to ride down there again, I'd go with a tour.
Just my .02
Rick
