I hope the asking price was a typo, the seller claims it is untouched and has only done seven hours, how does he know? They don`t come with an hour meter.
The paint on the crankcase is a different color from the paint on the cylinder and cylinder block and it has copper cooling connections.
Just about everything about this unit makes me suspicious but what is much more worrying is that there are 15 stupid people who have added it to their watchlist!
