It is also important to ac-custom the rider to the motorcycle dur-ing this time. Please read the followinginformation carefully.Since the engine is brand new, do notput an excessive load on it for the first 5hours of operation. The various parts inthe engine wear and polish themselvesto the correct operating clearances.During this period, prolonged full-throt-tle operation or any condition that mightresult in engine overheating must beavoided.
