Default Re: Engine break in?

When I'm breaking in an engine or have changed piston rings I'll break it in by running a richer oil/fuel ratio than normal for the first tank, and for the first half a tank try keeping at or below half throttle, and finding lots of hills to go up while at half throttle, for the remainder of the tank, riding like normal but trying not to keep full throttle for more than 5-10 seconds at a time.
