Thanks. It's a 2010 . They usually are just a wavey washer and a formed circle seal with holes in the right place. I guess 6 different sizes would cover 90% of bikes made since Indian Boardtrackers (facts and figures purely made up). I could pull the thing down and with a friendly shop match up with a 1998 KTM 250. For which I won't be able to get parts for anyway.
