Changing the engine oil and the oil filter, cleaning the oil screen *
NOTE: The LC8 engine has a dry-sump lubrication system. The engine oil is
pumped from the oil sump in the engine case to the oil tank. The engine oil
must also be drained from the oil tank during an oil change. Since many parts
must be demounted for an oil change, we recommend having the engine oil
changed by an authorized KTM workshop.
During the guaranty period, the oil change must be performed by an author-
ized KTM mechanic. Otherwise, the guarantee will become void.
The engine oil change is to be carried out when the engine is still warm.
AN ENGINE HAVING BEEN RUN WARM, AND THE ENGINE OIL IN IT IS VERY
HOT – DO NOT BURN YOURSELF.
Park the motorcycle on an even surface in an upright position. Place a ves-
sel under the engine to catch the used oil and remove the oil drain plug [1].
Remove the oil drain plug [1], take off the cap [2] and pull the oil sieve out
of the engine case with a pair of pliers.
Remove the oil filter cover [3] and pull the oil filter out of the engine case
with circlip pliers (upside-down).
Remove the screws [4], loosen the screws [5] by 2 turns and remove the front
spoiler towards the front.
Remove the drain plug [6] on the oil tank and allow the oil to drain into a
receptacle. Remove the screws [7] and tilt the oil return valve [8] to the side.
Carefully pull the oil screen [9] out of the oil tank.
Thoroughly clean the drain plugs, the cover and both oil screens. Clean all
rubber seal rings and check for damage. Replace if necessary.
