OPERATION AND IMPORTANT RIDING POINTS6-36FrontRearEAU42031Engine break-inThere is never a more important periodin the life of your engine than the first 5hours of riding. It is also important toaccustom the rider to the motorcycleduring this time. Please read the fol-lowing information carefully.Since the engine is brand new, do notput an excessive load on it for the first5 hours of operation. The various partsin the engine wear and polish them-selves to the correct operating clear-ances. During this period, prolongedfull-throttle operation or any conditionthat might result in engine overheatingmust be avoided. However, momen-tary full-throttle operation under load(i.e., two to three seconds maximum)does not harm the engine. Each full-throttle acceleration should be fol-lowed with a substantial rest period forthe engine. To allow the engine to cooldown from the temporary buildup ofheat, cruise at a lower engine speed.After the first 5 hours of operation,thoroughly check the motorcycle forloose parts, oil leakage and any otherproblems. Be sure to inspect and makeadjustments thoroughly, especially ca-bles. In addition, check all fittings andfasteners for looseness, and tighten ifnecessary.NOTICEECA10271If any engine trouble should occurduring the engine break-in period,immediately have a Yamaha dealercheck the vehicle.
