I have found that exactly 65 is the sweet spot for my bike. 63-56 or something, vibrates too much in 5th. Once i hit 65 it all smooths out. 70 is not bad either but i just don't really care for the wind at speeds above 70

I will undoubtedly be told how wrong I am, but here goes anyway. You will be pretty close if you figure an average speed of about 43 mph. When I was flying one of my flight instructors said "Most people have about a two-hour bladder." The Savage/S40 has about a 110-120 mile range to reserve, which is about two hours. So, every couple of hours you will be stopping for at least a few minutes. Those stops lower your average speed. If you are on the Interstate running 70 or so, your fuel mileage drops and so does your range - which means a stop about every 90 minutes. For a longer trip such as an all-day run, figure in at least half an hour to an hour for lunch. That cuts the average speed considerably. Feel free to cite the examples of the Iron Butt guys running 1000 miles in 24 hours - then calculate the average speed as 41.7 mph.

By the way, if you travel with a group and plan to stay together, the fuel stops will be more frequent and longer. There will always be someone who "doesn't need gas yet" but who will before the next planned stop. And, unless you stop at the fabled Little America Truck Stop in Western Wyoming (which was said to have 100 fuel pumps) everybody cannot fuel at the same time.
