I have not been able to ride my 04 S4R for the last 4 months or so due to a knee surgery. I finally rode it for the first time a few days ago for about an hour ride. When I got back I noticed a few drops of oil coming out of the large bolt holding on the left rearset and runing down the rearset, which is completely new. I could not find oil any where else around the area. Does anyone have any ideas on this?
