Hey, I am looking to buy a LT and I have a question concerning a 2006 I am looking at. I got down on the floor and looked at the bottom of the engine around the area of the center stand. In that smooth area under the motor right behind the oil filter cover the bike has black oil film on it. I have read in this forum concerning a leak between the engine and transmission, but this are is in front of that. It is the smooth area that is about 4 or 5 inches long right behind the oil filter cover. It is a black color oil mixture. The bike has around 39K miles on it. Please let me know if this a issue I need to be concerned about. I don't want to buy a LT and have a big repair bill before I even get started riding it. I appreciate all the expert help from the experienced owners on this site.
