As far as burning oil. After doing a oil change, try keeping it under 5,000 rpm.
My 2011 used a little oil, at first, when I would run over 5,000 rpm.
Since then, I have kept it under, except for passing etc. No prolonged running over that rpm.
I have over 28K on it now, and don't burn any oil, in my 3,000 mile oil change interval.
I know some have to ride at that speed, but here in N.H. I can cruse the highway at 70 mph=5,000rpm, and am good with that speed.
I try to ride as many back roads as possible. More to see.
