I am coming to the party late and really don't want to read the entire thread. I have had my 2015 for about 4 months. There is a noticeable whine at take off. From what I gather that is not normal or good?! And I should replace or add to the Angle drive oils with Lucas Heavy Duty Oil Stabilizer? I have also noticed that my belt tension seems a little looser then I would have it. Is there a spec or recommendation as to what it should be? Thanks in advance for your help.SlingLow; I don't consider your comments argumentative at all. Its always worthwhile to get as much feedback as possible and then a person can make his own mind up about it. Personally, I feel comfortable using the extra amount of gear oil. If you read all of LILB93's engineering action's with the AD and accept his premise, and others as well, that it is a poorly made drive, and that's putting it mildly, then there is much room for improvement. Based on his findings, I don't believe one should necessarily buy into the argument that "the Polaris engineers know best". If they did we wouldn't have had so many recalls.
Hopefully some of the other folks who are running extra oil will report how its worked out for them. I'll let you all know if it causes any problems in mine. I has decreased the noise level, and hopefully will better oil the bearings and gears and make them last longer. Cheers.
