ULMER RACING has made oil changes easier for your RX-1 (or Warrior) or Apex (or Attak). Some folks find accessing the stock oil filters somewhat difficult with these sleds, but not anymore! With this kit a do-it yourselfer can move the stock oil filter on a Yamaha 4-cylinder snowmobile for better accessibility. The kit is available for 2003-2005 Yamaha RX-1 models, 2006-2010 Apex models and 2011-2012 Apex models. Cost is $175. More info:
