I bought a used 2010 RZR "S" with about 500 miles on it that is bone stock and wondering if it suffers from the filter intake problems of previous years? Is there something I should do to it or just the regular keep up on the filter maintenance? Also is there anything else particular to this year that I need to keep my eye on? I am hoping to eventually turn this one into a race RZR that I can do some WORCS series races in since I can't really afford a 900. I know it won't be competitive like the 900's but I would still have a blast even coming in last.. Any tips or tricks you can help me with would be appreciated..
