I have been fighting this problem on a 10 ultra since 2,000 miles. don't ask about the warranty as that is another story. I have replaced the bearing 4 times, the seal 6 times and the entire trans at 18,500 miles. I currently have 37,816 showing and this thing is dripping badly. I haven't ridden it since it was shipped home by haulbikes.com in August.(another nightmare). I am about ready to tear it apart for the last time and need serious help with why this leak cannot be stopped. is the engine out of square to the trans or do I need a new inner primary cover that may be warped or machined wrong. no help from HD so I need real experts. I have all winter as I have an rk police I'm riding now with no problems. HELP!
