I have a 2012 Rincon with extremely low miles and hours, sadly only serviced once. It was last ridden 18 months ago and has been sitting in my garage. Any recommendations on what all needs to be flushed and a reasonable cost at a service provider? I figure oil, coolant, transmission fluid, brake fluid, diffs and drain the gas tank. I finally have some folks to ride with again and want to throw it on the trailer and go again. It has been too long. Thanks for the advice.
