Looks good for an old sled. I used to ride my dad's '68 Olympique (single cylinder 333cc I think) back when I was 12. I remember having to squirt gas in the cylinder to get it started on cold days. From the serial number, I think it is a 1969 but from my memory, it looks pretty much the same as what I used to ride.
