But, that does not answer his question, and I can't answer it either. The "squirrel cages" for the no cabin filter setup are smaller (in both diameter and length) than the "squirrel cages" for the with cabin filter setup. Gsxr documented that.

I don't know if the diameter of the rod the "squirrel cage" is pressed on is the same the both model blower motors. I recently replaced the blower in my 300TE, and the diameter of that rod is 8mm, the distance from the outer end of the left rod to the outer end of the right rod is approx. 220mm, and the diameter of the motor body is 73mm.
