Tonight I was working on my clutch, when I happened to get curious and shine a light into one of the oil channels going into the center of the motor. I saw something that didn't belong there, which when I pulled it out turned out to be a washer about 1 inch in diameter. I have a feeling that it got in there a couple months ago when I had the shop put a new starter clutch in. Any ideas what this came from and if I should be worrying about it at all? I swear every time I fix something on this warrior I find 5 new problems with it.
