Jarred,
I have a Southern California "Mad Maps" with about 35 recommended loops on it at home. Recently, I had the pleasure of riding South and East grade roads (I think off the 76 or the 79 or one of those 70's south of Temecula) to Mount Palomar. These are pretty awesome. Also, Ortega highway and the other side of 74 (Pines to Palms) highway. And the 243 is super awesome. I recall some quality roads further south, I will send you specifics when I get back next week.
An excellent book to check out for great rides is Motorcyle Journeys through California and Baja by Clement Salvatori - which can be found here:
