After riding through some mud I decided to pressure wash my 500. During the cleaning operation I found an aproximately 4" round rubber plug type part that I must have blown off. I looked the machine over a few times and looked through a few parts diagrams to try to figure out where it came from. It is definitely from my pioneer as it has Honda printed on the inside and also 040. If anyone knows where it came from I'd love to find out.
