      Common misconception is that you need to return to the dealer for an exact
      oil filter for your ATV.  Aftermarket companies actually make filters for
      the O.E.M. market. Why go to the dealer when you can get the exact filter you
      need at your local auto parts store such as CARQUEST or NAPA. Wix corporation
      makes ATV filters that you'll find in most of your popular autopart stores. 
      In most cases, you'll pay allot less! 
      WIX is a leader in the filter business.  Check out this
      ATV FILTER CATALOG.  Remember, you can
      right down the filter # and have it cross-referenced at your local autopart
      store if they don't carry WIX, CARQUEST, or NAPA.
      You can also click on the part # for the filter image.

      I have a 1995 Yamaha 350 big bear and I am having trouble starting it. You can hear the solenoid click but starter motor won't engage. Should I be looking at the starter motor or solenoid?  Any suggestions are appreciated.
