Does anyone know the # of teeth for a 550 SXV stock starter setup (Double gear, Intermediate Gear, and sprag gear???) vs the "updated" gears?

Or does anyone know any other way to see if the gears have been updated? ( based on serial no? production date?)
Thanks
Tim

Is that the updated gears for the 06 and 07 bikes?
