For the 2005 G22-AB G-MAX, the factory reference is LIT-19616-22-04. Yamaha's records give the code G22AA for this car, which is worth noting when a badge and a code do not read the same.
The manual covers the whole 2003 to 2007 G22 and G23 range, fifteen variants including the electric cars and the UMAX Medium Duty utility models, so the shared chassis and drive material is written once and applies across them.
Engine chapters take the carbureted motor apart in the factory sequence, with the valve, cylinder and piston limits printed where you need them. Fuel system, starter generator, clutches, brakes, steering, suspension and bodywork each follow the same pattern. The electrical section carries complete diagrams and the expected readings for switches, solenoid and charging.
Use the part number and the code together when checking fitment; on a car with several close siblings that is the only reliable way.
