Cleaning the air filter *
The air filter must be cleaned at intervals depending on the amount of dust
accumulated. To clean the air filter, first remove the seat. Then press both
retaining clips
1 , remove the filter holder and the air filter 2 . The air filter
consists of a foam rubber insert soaked with filter oil.
! CAUTION !
– D O NOT CLEAN THE FOAM FILTER WITH FUEL OR PETROLEUM SINCE THESE WILL
DAMAGE THE FOAM . KTM RECOMMENDS THE PRODUCTS MADE BY T WIN A IR FOR
AIR FILTER MAINTENANCE .
– N EVER OPERATE YOUR MOTORCYCLE WITHOUT AN AIR FILTER . O THERWISE , DUST
AND DIRT MAY GET INTO THE ENGINE AND LEAD TO INCREASED WEAR .
– T HE HOLDER MUST RETAIN THE AIR FILTER THROUGHOUT ITS ENTIRE CIRCUMFERENCE .
I F THE FILTER HAS BEEN MOUNTED INCORRECTLY , THE ENGINE WILL TAKE IN UNFILTERED
AIR , THEREBY CAUSING INCREASED ENGINE WEAR .
Thoroughly wash the foam filter in special cleaning fluid and allow it to dry
well. Only press out the filter, do not wring it out under any circumstances.
Oil the dry foam filter with a high-grade filter oil. Also clean the air filter
box. Check carburetor collar for damage and that it is filled correctly.
Insert the air filter in the opening and fasten it with the filter holder. Then
mount the seat.
Exhaust system *
The silencer is filled with glass-fiber yarn for damping. When in use, the
glass-fiber yarn becomes loose or coked with oil carbon. This can lead to a
power loss and a reduction of the silencer damping. The glass-fiber yarn
packing can be replaced in a few easy steps.
To replace, remove the silencer from the vehicle and mark the position of
the outer tube
3 to the inner tube 4 . Remove screws 5 and the end cap
6 . Pull of the outer tube and remove the old glass-fiber yarn packing 7
from the inner tube. Thoroughly clean all parts.
To assemble, mount a new glass-fiber yarn packing onto the inner tube (see
illustration) and slide into the outer tube. Mount end cap and fix with
screws
5 . Before tightening the screws, turn the outer tube until they
match the positions you marked. Mount the silencer and check the exhaust
system for tightness.
NOTE: Glass fiber yarn packages are offered by your licensed KTM dealer.
