3k isn't bad. Shoot, I threw 4 for my 92' SE and still wonder if it was worth quite that much.
As for getting it back to the states and getting it titled, I've heard nothing but bad news for CA. If I can, maybe taking out the motor, pull off the fairings, unbolt the expansion chambers and remove the model number (or not, not sure if it'll hide what it is) then just get the frame re-stamped when it gets to the states as a CBR250 or something that won't raise a fuss. I run across vin's from junkyard bikes all the time where I was from. I've heard something about a "special operations" vehile title before, but haven't looked more into it.
