Hi Jon,
the part you mean is the gasket ring between cylinder and head. He is made of several steel-rings pressed together with gasket-material. This gasket is needed to seal the space between cylinder and head. I hope I could help you!

Hi Jon.....Bob here. I have an XV920RH. A couple of years ago I renewed the rings. At that time I used aftermarket head gaskets (those springy things you wrote about). The aftermarket gaskets are not the same as the genuine Yamaha ones. Using the cheaper aftermarket gaskets cost me a head, as the front cylinder gasket failed and scoured out a large area of the head. The Yamaha gaskets look like inner and outer copper rings with a grooved ceramic material between. Spend the extra $$$ and get the Yamaha gaskets.
Bob
