Stay tuned to my thread this weekend, I am sure I'll have more questions!
It is a damper for the cam chain. It goes to the front of the cam chain tunnel between the cylinder and head. DONT assemble without it. It will become obvious when you look at where it goes but if not you can probably look up placement on fiche and ronayers.com
