I Purchased 2011 HDX 700 yesterday. Looking to replace the stator. I see Artic Cat OEM stator (PN: 0802-041) for $450 to $500. I also see several on ebay & elsewhere that are non-OEM options for $75 or so (Caltric & Celox are 2 of mfgs. shown for aftermarket options). Has anyone tried out the cheaper non-OEM options & if so are they worthwhile or are they cheap knockoff junk to be avoided?
