Cleaning of air filter *

To do this, remove the seat and the air filter cover from the air filter box. Unclap
the filter holder [1], swing back and remove air filter plus filter carrier 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 and 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 support [2]. Grease the front side [A] of the
filter, to improve the seal. Mount the air filter and the filter support in the fil-
ter box. Make sure they are centered [B], and lock into place with the filter
holder [1].
– DO NOT CLEAN AIR FILTER WITH FUEL OR PETROLEUM SINCE THESE WILL
DAMAGE THE FOAM. KTM RECOMMENDS THE PRODUCTS MADE BY MOTOREX
(BIO DIRT REMOVER AND LIQUID BIO POWER) FOR AIR FILTER MAINTENANCE.
FOR CLEANING PURPOSES AND TO OIL THE AIR FILTER.
– NEVER OPERATE YOUR MOTORCYCLE WITHOUT AIR FILTER. OTHERWISE,
DUST AND DIRT MAY GET INTO THE ENGINE AND LEAD TO INCREASED WEAR.
– HAVING MOUNTED THE AIR FILTER, CHECK IT FOR CORRECT FIT. THE FRONT
END A MUST ABOUT THE AIR FILTER BOX. OTHERWISE, DUST AND DIRT MAY
GET INTO THE ENGINE AND LEAD TO INCREASED WEAR.

Exhaust system *

660 SMC silencers are filled with glass-fiber yarn in the front and insulation
matting in the rear for dampening. The influence of heat causes the glass-
fiber yarn to become loose. This can lead to a loss of power and reduce the
silencer's dampening effect, therefore only the front glass-fiber yarn set [7]
must be replaced.
To replace, detach the silencer from the motorcycle and remove the front cap
[8]. Pull the front glass-fiber yarn set including the inner exhaust pipe [9] out
of the silencer. Clean the front inner exhaust pipe.
Slide a new set into the silencer. Replace O-Ring [10]. Then push the inner
exhaust pipe into the silencer and mount the cap.
THE EXHAUST SYSTEM BECOMES VERY HOT WHILE THE MOTORCYCLE IS RUN-
NING. TO AVOID BURNS DO NOT START WORK ON THE EXHAUST SYSTEM UNTIL
IT HAS PROPERLY COOLED DOWN.
