According to Moto Tune USA's website, you must make sure that you seat the piston rings right off the bat. This is done by gradually accellerating to high rpms, and then let the motor decellerate with pressure on the motor. This will force the rings against the cylinder walls. Not doing this, according to them, is a surefire way to decrease engine life and performance. Most engine builders will tell you to break in a bike, or any four stroke motor, by riding/driving it like you intend to drive/ride it on a regular basis. This doesn't mean to go out and beat the snot out of it right off the bat, but you should run through the gears with a decent amount of throttle.
They also express the importance of running the engine through "heat cycles". Run the engine for 10-15 minutes, letting the engine get up to temperature, then shut it down, and let it cool off for an hour or two, and repeat this cycle four or five times. Your engine is now broken in correctly.
I've used this program on my last five four wheelers, and they don't burn a drop of oil, and they seem to run stronger than friends that have the same quad, and babied them for the first two tanks of gas.
