Cleaning the air filter (LC4 Enduro) *
It is very important for the engine's life expectancy to clean the air filter
regularly.
To clean the air filter, remove screws [1] and the filter box cover. Detach retain-
ing clip [2] and remove the air filter [3] including the filter holder [4] from
the filter box.
Remove the air filter from the filter holder and wash thoroughly in special
cleaning fluid. Motorex offers environmentally-friendly products for professional
oil filter maintenance (Motorex Bio Dirt Remover + Motorex Liquid Bio Power).
Press out the water from the air filter but do not wring and allow the filter to
dry. Lubricate the dry air filter thoroughly with highgrade filter oil, rubbing to
coat the entire filter surface.
Clean the filter box and cover and check the carburetor connection boot for
damage.
Mount the air filter on the filter holder, position in the filter box (make sure
to center) and fix with the retaining clip. Check whether the air filter is posi-
tioned correctly and mount the filter box cover.
– DO NOT CLEAN AIR FILTER WITH FUEL OR PETROLEUM SINCE THESE WILL
DAMAGE THE FOAM. KTM RECOMMENDS THE PRODUCTS MADE BY TWIN AIR
FOR AIR FILTER MAINTENANCE. FOR CLEANING PURPOSES AND TO OIL THE
AIR FILTER.
– NEVER START YOUR MOTORCYCLE WITHOUT ANY AIR FILTERS. OTHERWISE,
DUST AND DIRT MAY PENETRATE AND CAUSE DAMAGE AND INCREASED WEAR.
– DUST AND DIRT CAN ACCUMULATE AND DAMAGE THE ENGINE IF THE AIR FIL-
TER IS NOT MOUNTED CORRECTLY.
