I just read thru this whole thread, start to finish. Very entertaining! I've run entire tanks of gas at or above 90mph on long expressway trips. Never had a problem. Change the oil a little more often if you're worried about it.
On the other topic in this thread, my stock 1600 would hit the wall at about 105-107 indicated (my speedo is about 3mph off) After the 42mm Mikuni, Dyna
3000, ported intake manifold, Dyna coils, and K&N, she indicates 120mph on a nice long stretch of road
that was nothing on an R1, but I like to keep this one under 100mph.
