2009年9月30日 · YAMAHA YZ250F JETTING:FROM 2001-2009 (9/2009) As the original 250cc four-stroke of the modern era, the Yamaha YZ250F has the most development and refinement time of any bike of the track.

2010年3月25日 · green antifreeze mixed 50/50 with water will work just fine. you can buy it premixed or you can buy it straight and mix it your self. a gallon of 50/50 is about half the cost of a gallon of straight because obviously you are buying half a gallon of antifreeze and half a gallon of water. don't ever mix orange and green antifreeze they will coagulate and cause all sorts of …
