No can do, my Famas assault rifle is welded to my moped. And yeah a G might be hard to get for a pa50ii (I got a pa50ii 83 black with blinkers and in great shape for 300 in Boston).
But she is pretty and all that work does equal to be a ripper moped! Dont sell it, keep it!
Posting on CL might get you some good results too.
