Asking this question for a relative. He has an '07 600rr. It's been leaving oil spots, just a drop or two, when he stops for about an hour or so. We took the fairings off and found the left side was covered in oil. Cleaned it up a little, fired it back up, and found that the pulser is where the leak is originating. The o-ring looks fine, but I guess that will be the next thing to try. Anyone else have this issue?
