I just replaced with an orginal sherco key, but now i don't find anyone chisel mark ! Now the only way is the dial gauge?

 

-Second question is.... What yellow do I have to buy for the '13 frame?

Thank you so much!!

From what I can see your woodruff key was 3/4 sheared rather than made that way. Just refit the stator in the same position that it was in, looks like centre of the slot going on the witness marks from the washers

Should be pretty close to right

It change the ignition timing maybe of 2 degree.    If you tell me "use the old position" i use the old position , thank you !  ;)

This would work. The key is just for alignment. It isn't what holds the flywheel in position. Ask anyone who didn't use a proper torque wrench to reinstall the flywheel.
