Hello all, new guy to the forum here. I just purchased a new to me 2015 Sportsman 570 a few days ago, and I already bought a winch to install on it. I have already had some experience with Viper winches and was happy with their performance, so I decided to go that route again. After doing some reading, it seemed that the KFI mount was the best mounting option. I just got both items in today and decided I would see about installing them on the quad this afternoon. I was shocked to find that my winch doesn't fit inside the mount. I'm not sure why as I seem to recall seeing people say they had used this combination before. Maybe something changed, but there is no way the winch will go inside the mount without doing some serious modification. I just wanted to put this out for someone else in case they run into the same problem
