Same code, different book. A 2014 Adventurer Sport EFI still reads YTF1AX4_SPORT, but Yamaha moved its service coverage to part number LIT-19616-29-12, which spans 2014 and 2017 and ten configurations in total, from the Adventurer One EFI and the DC Adventurer Sport through the Drive Adventurer Sport 2+2, the Concierge four- and six-passenger cars, the Drive Fleet EFI, both Drive PTV variants and the Fairway Lounge beverage car.
Use the EFI chapters: injector and fuel pump testing, pressure specifications, sensor values, throttle body service and the diagnostic order for a fault under load. Valve clearance and torque data are given as published figures.
The shared chassis material covers clutch and belt, rear gearcase, brake adjustment, steering, front suspension, wheels and frame. Wiring is diagrammed per configuration.
Confirm both the code and the model year before ordering.
