I had a very mild close encounter with a cage that cut me up end ended with the bike laying on its right side. the only visible damages are a few scratches on the mufflers heat shields and rear indicator. I have since noticed a small oil patch under the bike. At first, I thought that it came from having had the bike on its side or from the oil tank drain hose or the transmission drain plug that might have been damaged as the result of bottoming on a speed bump. On closer inspection, however, I found that the oil was collecting behind the rear cylinder and that the leak originated in the area marked by the arrow on the picture. The leak is small, the oil is clean and the bike feels and performs as usual. The bike is a 2007 Sporty with 7000 odd miles on it and is not ridden unreasonably hard. Any suggestions? Thanks in advance.
