Break in period

One question for everyone that likes to hit red-line before the first oil change: are you not worried about metal shavings cycling through the engine with the oil? Isn't that one of the main reasons for low RPM's at first, to cycle the oil at a slower rate, increasing the chances metal will stay at the bottom of the oil pan?

Simplest way to understand this - assuming you've ridden a mountain bike or multi-speed bike. Put your pedal bike in 1st gear and sprint to your maximum speed. You should reach your maximum speed quickly and with little effort.

Now do it again in a middle gear... it'll take a lot more effort to get to that max speed (load to an engine), not just time.

If you're a glutton for punishment, put it in its top gear now (10th, 18th, 24th, whatever) and repeat. Have water handy and be ready for your quads to scream at you.
