Here is a pic with the motor against a Pletty, C50 Hacker and a 1512 Tekno Neu. Yes that is a 3 slot stator, just like the little x12 brother and x11, x10, x9 cousins. The rotor is 13mm. Stock Timing insert is -5 degrees. Instruction manual states that the fan has to be used at all times. Go figure.
