The Yamaha XS750 was a significant motorcycle in Yamadas lineup during the late 1970s, featuring a distinctive 747cc DOHC inline three-cylinder engine that offered a compelling balance of performance, smoothness and reliability. Shaft drive made it a practical touring companion while the triple cylinder configuration delivered power in a way no twin or four could match. Available standard, as the custom-styled Midnight Special, and as the sport-touring XS750G, this platform earned a loyal following that endures today. This comprehensive workshop manual provides everything required for proper maintenance and restoration including complete engine rebuild procedures, triple carburetor synchronization instructions, shaft drive service, electrical system diagnosis with full wiring diagrams, chassis and suspension overhaul, and detailed exploded views with factory torque specifications. Whether maintaining a daily rider or restoring a classic to concours condition, this manual is the definitive reference for XS750 ownership.
1976-1981 Yamaha XS Series XS750 Service Repair Workshop Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The Yamaha XS750 emerged in 1976 as Yamahas bold answer to the popular inline twin and inline four motorcycle segment of the 1970s. Designed to bridge the gap between the XS500 twin and the legendary XS650, the XS750 featured a pioneering inline three-cylinder engine configuration that was relatively uncommon in Japanese motorcycles of the era. Built at Yamadas facility in Japan, the 747cc DOHC triple delivered smooth, torquey power with less vibration than singles and twins while offering better fuel economy than inline fours. The XS750 evolved through several variants including the XS750-2, XS750D Midnight Special with its distinctive custom styling, and the sport-touring XS750G. The shaft drive system eliminated chain maintenance and positioned the XS750 as a capable highway touring machine.
