I recently purchased a used 2004 KX250F. I have installed a Boyesen water pump/oil cover with impeller to aid in cooling. I am thinking of running coolant, what would you recommend?
We used WaterWetter or Maxima Coolanol on our 2004 KX250F (both were recommended by the Pro Circuit team). We also changed the stock radiator cap for one with a 1.6 pressure rating.
