Yes the motor has had minor changes, if you care so much and you must, because you seem to just troll the new posts waiting to jump in on any thread to do with polaris. We get it, you hate Polaris, you ride the greatest mountain specific sled on the market, good for you, to bad for us. Why on earth do you care about what Polaris is doing? Why not just google polaris to find out all about them. You are the classic Internet troll. Go back to doo-talk.
Seems like a legit answer. Also heard there has been no change.
