What kinda bike is it? was it a ninja 250 off ebay? If so, i was looking at it as well.
I did some research, and it sounded like a pain, so didnt go for the bike. Pretty much you just have to make it look pretty again.. fix all the broken stuff. On the fairings, she wasnt sure if they had to be new(non cracked) or if just getting them painted so you dont see scratches is enough. You get it all good and ready, then you schedule an appointment at the Palmetto DMV office/tax collector office, and the guy will look it over then. Best bet is to try to call that office, and speak to someone who knows for sure.
Then it can be registered. Only problem is figuring out what has to be fixed, and what is fine.
