I have a box of engine parts from a chinese mini bike similar to the honda trail...forget the name, but its the one that is in all of the bikes that use the three speed gear box deal.
My boss has one of these sitting in the back of the store, Its mint. I think he said he has never seen one with as low of miles. I'll see if he wants to get off it, but He knows it got some value.
You wouldn't be interested in a couple of motorized scooters would you? As in a larger version of a razor type scooter with a weedwhacker motor on it type of thing.
