I just wanted to let everyone no that I just got off the phone with unifilter and they are now available for the DS650.I talked to someone in technical support who told me they were already shipping but they did not sell from the factory.So I called about 20 places in dirt wheels magazines and no one had heard of the part # that they gave me at uni.So I ended calling back uni and talking with the lady at the front desk and she said she didnt no why the guy in the back said I cant order through the factory and she took my order right then and there.Who ever said that secretarys dont no there stuff She should be in the back and the dumbass in the back should be up front answering the phones.Well if anyone wants to order one the part # is nu-8701st and they are $29.95.I forget their phone # but its on their web site at www.unifilter.com.
