Here's a site that will give you some ideas on proper engine break in...

This is my advice for breaking in a new motor.

Find a road where there is no traffic and get it up to third gear. Accelerate from 30-60 using a substantial amount of throttle (around 3/4 + ) and coast back down to 30 again letting the engine do the breaking for the bike.
Do this 10 times and your rings are seated. Keep speed to a reasonable limit and vary it on the parkways with no lugging and no high RPM's. Change the oil and filter at 100 miles,then enjoy it.

What this does is to load both the top and the bottom of the rings forcing them out against the cylinder so that they seat evenly all around the circumference.
