      Worked great!
      Travis W. on 07/27/2010
      Pros: Worked great on my 2008 Yamaha WR250R.
      Be sure and get the Graves Motorsports EXUP Servo Eliminator if you're removing the EXUP.
      Dimple/dent just before the muffler can is in fact supposed to be there for passenger foot peg clearance.
