I really wasn't surprised. I think break-in is more important for valves and rings and such.
That said, I did keep it under 4k for about 500 miles, which for me was less than 2 weeks to work and back.

I rarely take it over 6k. Scares the heck out of me on the roads around here.
There's too many moguls.
I've gotten air a couple of times at about 6500.
