On my new (used) 2007 450 Rhino I just got I noticed what appears to be a problem. When going down hill it, to put it best comes out of gear and freewheels until I slow back down. This does not seem natural to me, is it the clutch going bad? I am new to the Rhino lifestyle so I am learning the quirks as I go. Thanks for any help. And my Rhino has 27" Maxxis Bighorn tires. I do not know of any previous maintenance on the Rhino.
