    Have anyone used any aftermarket valve seat cutters on 04 WR250f or a 06 yz250f 5 valves heads. If so what brand you get ?? How did it work ?? Thank you
  2. Motocross and Offroad
    Can anyone give me any tips as to why I keep fouling my plugs. I have a 2021 yz125x with about 12 hours on it and I went through about three plugs. I don’t lug it or ride it soft so it’s run mostly wide open. I’m running yamalube 2r with 93 pump gas.
