I read somewhere on the forum that some folks who were considering buying the UMP—-were concerned about excessive oil residue build up in the fresh air intake area (from the small FRAM PVC filter) that is relocated there with the UMP kit install.
I’m still sitting on the fence and was planning to buy the UMP for my RZR 800—before I saw this (“potential” problem). Most folks won’t be removing the bed on their machines that often to inspect the fram filter and fresh air intake area.

What are your thoughts on that? My worry would be that the oily residue could find its way into the CVT system. Can anyone with the UMP system chime in and offer any input on their machine? Thanks everyone!
