The Radiator is made in a “V” shape.

  • The 5/8inch 1,8288 meter long part is straight.
  • The bend starts there where the 1/2 inch tubing starts.
  • At that point the radiator is 0,956 Meter seperated from the reflector
  • At the end of the radiator the radiator is 0,565 Meter seperated from the reflector
  • In total the length of the 1/2 inch part should be 1,720 Meters ,making the total lenght of the radiator: 5,2688 Meter.
