If it has the covers like shift shaft, that has a flat spot milled into it for chain clear. Also the breather cover has reeds on the top., other then that they are the same.   Also maybe the # may start with a certain number. I know gen 1 I have seen 7 as the first. The gps is different too, it has no springs or plungers in the drum, just on the gps itself. The drum star is different as are the forks and the gear shifting shaft with the spline is longer then Gen1

GEN 1 oil pressure sensor is pointing directly down , but GEN2 oil pressure sensor points to the side a bit diagonally  :wink: Because there is a fairing mount in the way of sensor .  Am I correct ???
