All good advice. If S&S says don't lug it under 2,700 then don't. It's hell on the motor and the compensator will complain. It will not be happy. Even at 3,000 when I need to pick it up quickly I will downshift. The only time I run it lower is when there is absolutely no load. Some call it coasting...

What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.
