There seems a dearth of literature on proper ways to break-in or run-in a new engine, whether for a virgin car or motorbike. Car manufacturers recommend a gentle break-in, especially from 0km – 3,000kms. Motoman, a tuner based in the States, however, seems to think otherwise.
The controversial MotoMan wrote “Break-in Secrets” after applying his methods on over 300 new engines. He claims that by using his methods, engines would experience a dramatic increase in power over all RPMs, internals remaining cleaner and more efficient overall. His principles and examples apply to all 4-stroke engines – motorbikes, cars, airplanes, snow mobiles, lawn mowers!
So really, how true is this?
