I would reckon "cruising" at 10k would boil your oil
Twenty years ago when I lived in the Chicago area we used to run some top end runs down US41 south of St. John IND on early Sunday mornings. The road is dead flat and straight for over 25 miles and only ONE stoplight!! I always geared my bikes to pull redline in top gear. My Kz1000 and my GSXR750RG would sit at redline for mile after mile down this road. We always turned off US41 onto the same side road to hit the backroad twisty's. Always stopped at the same gas station at where we turned off for a can of pop and a few cigarettes. You could always feel the heat rolling off the bike's motors and oil coolers, but they all fired right back up!!!!
I always rode with a Cop or two just in case we got stopped for speeding. In all those years of doing those high speed runs we never saw a Cop on the road!!! Its funny when I would drive down that same road in a car it took almost a half hour to drive that same distance that we did in something around 10 minutes or so on the bikes!!!
