Considering a 800GS. I have a couple of questions. First, what is the valve adjustment interval. Second, can it cruise at 80 MPH comfortably. What's the tack at? Third, what is the average range on a tank? Lastly, can you run regular in it? On the BMW web site it says Premium but I have also seen that you can run regular. Thank you!
