Josh - if the feaux velocity stacks on your 1st bike are original, then that would be an '85. The other year Honda offered that color on the 700s was '84, but those had the black plastic velocity stacks.
Unlike Mike's observation, my first motorcycle was a 1979 Yamaha XS750 Special. In line triple, shaft drive, disc brakes. Really nice.
A few years later, I bought my first dirt bike, a 1970 Yamaha YZ250. Sweet mother of pearl, that thing was possessed!!!! You couldn't "ride" that bike in the conventional sense of the term. You "aimed" it and hoped for the best.
