Thanks! With the warning that I'm not recommending anyone deviate from the owner's manual, personally I didn't want to wait until 1000 miles to seat the rings and I also didn't want to just flip a switch at 1000 miles and suddenly start ripping to 7400 RPM at full throttle. So this was my break-in:
500 miles: 4500 RPM, 1/2 throttle
600 miles: 5000 RPM, 1/2 throttle
700 miles: 6000 RPM, 2/3 throttle*
800 miles: 6500 RPM, full throttle*
900 miles: 7000 RPM, full throttle*
1000 miles: 7400 RPM, full throttle*
*When I went 2/3 throttle and up, it was only at 3000+ ft elevation where cylinder pressures are lower due to decreased air density.
Lastly I also using engine braking at around 600 miles to try to seat the rings. So I'd gently rev to 6000 or 6500 RPM and then engine brake back down to 2000 RPM.
