I am the senior tech at a Polaris dealer in north central NE. I have developed a product that will stop your 850’s from melting the plastic on the right side where the exhaust is. I will have this ready around the first of the year. It will come with detailed instructions and only takes 10 minutes to install. Patent pending and then will be ready to hit the market. I have several out in testing for 6 months of continuous use and the plastic still looks like new and nothing has caught on fire. So bear with me until I can get this thing going.
