I'm sure this aluminum spacer is an aftermarket, that sits between the left engine case and the stator cover. Anyone know why it would be there?

Years ago I had a wr 400 that I put a Steahly flywheel weight on. It had the spacer like you discribe, it was needed because the flywheel weight made the flywheel wider (and heavier)

I think I'll have to take it apart and find out sometime. Not today though. I just got my license plate today so when it warms up outside (maybe in june) I'll see if the headlight is up to snuff. I still run that on the ac current. Thanks for all your replies.
