Nice, thanks for the heads up! Luckily the guy I bought it from included the original manual, so I've been reading over that in my spare time.
As for quirks, one example is that one of the previous ownes deemed to fit air horns onto it and wire them to the main horn button, while keeping a smaller switch for the OEM horn (which still works fine). I recently got it back from a local shop, where they changed the ignition, ar filter, battery, spark plugs, and both tires.
For now, it runs and I'm using it to learn. I'm inspecting and refreshing components as I go.
