I spent 7 moths registering my out of state, used GS Adventure. I had all the notorized paperwork completed in advance of my appointment. And still they kept requiring another form.
The best was registering my Audi fifteen years ago. They rejected it because it did not "say" "Audi" on the front of the car!
We finally got past that.
My next bike I'll buy new from within the confines of the republic of kalifornia.
I believe the mouth-breathing CADMV exists in an attempt to counter the weather. It took the original owner and me about fifteen minutes to conclude our business at the local DMV in Kansas City Kansas. The ladies there were all curious about my riding home and we ended up spending a lot more time talking. The nice lady even gave me a paper plate and extended it to 90 days instead of thirty.
The CADMV is like getting a flu shot; there is a little pain but it usually doesn't last too long. Though in this case it looks like they gave you bird flu.
