I was riding Saturday and...something didn't sound right, so I headed home. Sunday morning I checked the primary chain tension, it was 7/8. I adjusted it to 5/8 It looked like the rivets on the side of the chain were lightly scuffed. Here's a link to a photo of it. Anyhow, I changed all the fluids Sunday and took it for a test ride tonite, everything seems to be OK, shifts smooth, runs quiet, and finds neutral very easy.
