Occasionally I see threads about whether it's better to keep the engine revved up closer to the "sweet spot" or always seek to get it into 6th gear for better mileage. I rented an FLHT in San Francisco for the day Tuesday and decided, what the heck, it's a rental, let's experiment. I rode 215 miles of mixed type roads from VERY twisty to 80 MPH on I280. I intentionally never put it into 6th gear and spent the majority of the day between 3000 and 4000 RPM (I know Hobbit rides like this simply leaving his driveway!). I topped off the gas tank twice and guess what? Averaged 40 MPG both times. This is about what I get day in and day out on my FLHX so I was a bit surprised. Guess I'll be edging my riding style a little more towards the high revvers.
