The black PRO is a 2013 800 PRO RMK with maybe a 1000 miles. It's a friend of mines and it's been sitting in my shop for over two years and it's been over two years since he used it last. For some reason oil keeps leaking out of the exhaust. I have moved it several times and after I move it a new oil leak shows up on the floor. The red one is my 2014 800 with just over 1000 miles and there is no leaks from that one at all. Ever. I use it every winter. I am totally confused as to how it can keep dripping oil.
