decompressor spring

  1. Brass Plug Found in oil

    Engine/EFI/Drivetrain
    I recently traded for a 2009 kfx 450r with a cracked engine case. When I was draining the oil out of the cases I found a small brass plug with a spring connected at one end. At first I thought this was part of the decompresser assembly, but I am now not sure. All comments are appreciated!
