Whats the real proper break-in procedure?
The factory recommended break in procedure is designed to minimize early life problems and not necessarily to produce the best performing engine. Race engines are broken in on a dyno in a very short period of time. The consensus seems to be that a break in procedure which will produce an engine with the highest power output focuses on repeated heat cycles with incremental increases in both rpm and load over the break in period. So, what you should do is to break in your engine with numerous short duration rides that bring the engine up to operating temperature. Allow the engine to fully cool between each of those rides. Each ride should slowly increase the maximum rpm at which you bring the engine. In addition, you should also slowly increase the load on the engine. That is, the amount the engine must struggle to achieve rpm. For example, full throttle, up hill, in top gear is high load. At the end of the break in period you are running up to redline at full throttle. The worst thing y
