Expert Pro-Tip:

Precision is vital when overhauling these 4-stroke engines. We highly recommend using an official Yamaha service manual to guide your assembly, ensuring all bolts are tightened to factory torque specifications. Properly cleaning the crankcase and all oil passages before reassembly is critical for the long-term health of your new bearings.
