I have a brand new never opened Mountain Performance Transfer Enhancement kit that I don't need. I have one on one of my sleds and it's the best $50 you can spend on your Yamaha. They're $50 plus shipping or tax if you get it at your shop. I'll sell it to ya for $40 shipped (US only please). Here is some info on it from MPI:
