KTM 990 SUPER DUKE User Manual

To completely bleed the cooling system, the motorcycle must be raised approx. 50 cm (20
in) in the front.
Add cooling liquid until it runs out of the vent holes without bubbles and immediately mount
the screw to prevent air from entering the radiator.
Completely fill the radiator with cooling liquid. Mount the radiator cap and move the motor-
cycle into a horizontal position again. Now fill the compensating tank [6] with cooling liq-
uid until it reaches a level between the MIN and MAX marks. Close the compensating tank
and mount both spoilers.
