Here is a picture of a true '69:
Telescoping forks, plastic cover on frame downtube, rear rack, but NO snorkel tube from the airbox going up to the rack.
It's also my understanding that titling year vs. VIN wasn't required in the US until 1974, so a dealer would title a bike in the year it was sold, not (necessarily) the year it was built. The VIN is your best indicator of build date.
The best I can tell is it is a late model 1969. It shares some things with the 1970 model, but has a correct frame number for 1969. In researching this I've come across other 69's with a few of the newer parts, and some have newer yet parts. It seems that Honda made running changes to the bike, rather then a true model year change.
Thanks for your insight. Who know it may turn out to be the piece in the puzzle that changes everything.
