Yamaha G9 Serial Number Location

The serial number has a prefix, that designates the model, starting with a 'J' followed by 1 more letter and 1 number, or just 2 numbers. Following the prefix is a six digit extension. The serial number does NOT indicate the year of manufacture. You need all of these numbers and letters to assure that the correct parts are sent.

The early model G2 has the serial number under the rear bumper, toward the passenger side. It is stamped into the square tubular frame that the bumper bolts on to. The gas cars will have a 'J38' prefix and the electric cars will have a 'J41' prefix (i.e. J38-000204). I suggest a flashlight and damp rag to help find the number. In 1988 the serial number moved to the very rear edge of the floorboard, just behind the back edge of the mat, under the seat pedestal in the engine compartment. The number is a little easier to find in this location. The G9 models started in 1991 with the prefix 'JG5', also found under the seat pedestal.
