Well, not today, but this weekend. Finished top-end inspection reassembly after a partial seize-up on the highway. Nothing serious, thank goodness. Got back from three-mile test ride early Saturday evening and discovered my right leg covered in oil and my oil cap missing. Living in a suburban neighborhood, all the streets are curbed. Suggested to my wife that we take a Sunday morning walk with the casual intension to find the cap. We both decided this would be a nice way to start-off our 40th anniversary (also yesterday). Anyway, after tracking gutters on the righr-hand side of the street for about a mile, there it was, peacefully lying in the gutter. We both had a sense of accomplishment and amazement that this was a success. Also, it was a kind and inexpensive reminder to check oil flow after every startup, or, at least, the first startup of every day.
One more thing about this, not so straightforward if you drive on the left side of the street.
