i think he is talking about the stator
to do this u first remove the stator cover which is the plastic piece on the left hand side sitting on the quad
then u need a flywheel puller to remove the flywheel (or if u have air power u can use a impact wrench but the puller is the best way)
and then lastly u take out the two screws holding the stator in place
hope thats what ur talking about
