ISO Motorcycle Seller: Dongnae: red Daelim Magma 125cc

Hi,

Looking for the seller of my red Daelim Magma. Sold last year at Dongnae Station to an Asian-American. The starter was a bit funny. The bike had/has: sticker from Hot Topic and that Korean card game (with the crane) on the tank, 76 decal at the right side, and a flame head sticker on the rear. Came with NY license plate.

Trying to register the bike and get my own plates. I need -

-a signature on a sales/transfer document

-the old plates (for transfer) or the paper documenting its destruction.

Would greatly appreciate the aid. 

I'll forego posting the listed name on the registration paper.
