Hey folks. I just bought this 1995 Honda vfr 750 and within a couple minutes dropped it on it's side. After cussing profusely and picking it back up, I noticed this small circular piece laying on the ground. I for the life of me can't figure out where exactly it came from. I included some pictures. Any help would be appreciated. It's made out of metal and I dropped it gently and gracefully on its right side. Thanks!
