Greetings, just purchased a 97 Wave Venture 1100 as a project ski. I was told by the previous owner that he took it into a dealer and was told #2 cylinder was siezed so it needed a rebuild. I got it home and noticed that inside on the bottom there was a bunch of oil (and sludge) sitting in there. I feel this is odd because the oil resivor is still full. Does anyone have an idea what this might be from? Thanks.
