I bought a Kawasaki D-Tracker while I was living in Pattaya and moved in Bangkok later. Green book is in my name. Now I plan to sell the bike, but have no idea how to do it here. Like where to go, should I get some kind of paper from Pattaya, should I register in Bangkok immigration office (I am living on tourists visas, so don't really need it), and so on. Thank in advance for your help.
