Yamaha part number LIT-19626-00-33 is the service manual for the carbureted Fleet Classic, and for 1991 the model code on the car is G8AG.
Two seasons are covered, 1990 and 1991. Buyers should note the part number carefully, since a similarly numbered Fleet Classic manual carries a different and wider coverage span; quoting LIT-19626-00-33 with the code G8AG removes the doubt.
The work is laid out system by system. Engine and carburetor procedures with clearances and torque values, transmission and drive service, brake adjustment and overhaul, steering and suspension, then electrical diagnosis against the factory wiring diagram. Each inspection step names the measurement to take and the limit that governs it, so a rebuild finishes to the same standard the dealer network worked to when these cars were new.
