hi paul, love to help except my road trips are limited. it is going to be hot if you ride inland. you'll find cooler weather and beautiful landscape along the pacific coast, highway 1. check out santa barbara, cambria, san simeon, etc. all the way to san francisco. carrizo plains might be hot, but who cares as long you stay hydrated. take soda lake road (mostly dirt), it can be done on a road bike. a friend of mine who lives there rides his ninja250. head north and stay close to the coast, you'll be fine.
