They do that to all the machines......not just the XMR. But yes, I did the same thing when mine was new.....greased every connector before it left my garage. Much easier to do when everything is NEW and CLEAN!
For the dielectric grease. It depend more on the type of riding that you intend to do. I have been riding bikes of one sort or another for 50+ years and not had a problem. But then I do not run in the water. I do from time to time cross a stream or run in wet areas but do not have the bike submerged in the water. The ones that are having the problems are those who want to run the ATV as if it were a PWC. (Personal Water Craft)
No not havin any problems, just wanting to know where everythings at and how to fix/clean. In the process of greasing the connectors, some already had it but gonna put another layer to be safe. Thanks for the help
