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
1
to the inner tube
2
. Remove screws
3
and the end cap
4
. Pull of the outer tube and remove the old glass-fiber yarn packing
5
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
scews
3
. 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.
