Not sure where you are in registering the bike process, but here's how I had mine done.
Bike was out of system, no plate or paper work. I went to AAA to get the bike registered under my name and apply for new title. They gave me 30 days temporary registration with red paper tag to put on the bike. Got all paper work from AAA. Got insurance on my bike and you're back on the road. During this time, take your bike to CHP for vin check. Went back to aaa, turned in paperwork, paid fees, walked out with new plate.
