I've also been doing a "hard" break-in for my cars and motorcycles as well.
Warm up the motor to operating temp
avoid highway, I do most driving after midnight, less stop and go driving
hitting 70% of the redline for the first 150 miles
hitting 90% of the redline from 150~400 miles
routinely hit the redline after 400 miles (with the engine warmed up of course)
lots of engine brake and varying RPMs
