FOR CLEANING PURPOSES AND TO OIL THE AIR FILTER
.
Thoroughly wash the air 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 air filter with a high-grade filter oil. Also clean the air filter box.
Check the carburetor collar for damage and that it is filled correctly.
Mount the air filter on the filter support. Mount the filter together with the
filter support in the filter box, making sure to center them, and fix them
properly with the filter holding bracket.
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
4
to the inner tube
5
. Remove screws
6
and the end cap
7
.
Pull of the outer tube and remove the old glass-fiber yarn packing
8
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
6
. 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.
