(not mine)
Looks pretty nice and original. Just some corrosion on the fork lowers, split fork dust covers, and the rib on the seat cover looks to be a little low on the front half (cover pulled too tight?).
Low miles, claimed mileage of only 1,020. Wonder if that's true? Tires look as if they may even be the original Yokohama bias ply shoes (couldn't see any date codes when zoomed in), and the carb vent and overflow hoses may be original too.
