Replacing the glassfiber yarn packing of the silencer *
Aluminum silencers are filled with glassfiber yarn to muffle noise. Have the
filling checked regularly by an authorized KTM workshop (see Lubrication and
Service Chart). The insulating material fibers escape through the holes in the
perforated pipe with time, causing the silencer to “burn out“. In addition to
causing a higher noise-level, it will also affect the power characteristic. The
insulating material suitable for your exhaust is available from your authorized
KTM workshop.
To replace, remove all screws, take off the cap
[1]
and outer pipe
[2]
. Pull
the glass fiber yarn packing
[3]
out of the inner pipe
[4]
. Clean all parts thoroughly.
Slide a new glass fiber yarn packing over the inner pipe. Mount a new O-ring
[5]
and slide the outer pipe over the glass fiber yarn packing.
Mount a new O-ring
[6]
and insert the cap in the outer pipe; mount and tighten
all screws.
NOTE:
In every exhaust repair procedure, the O-rings must be replaced by new ones.
Glass fiber yarn packings are available from your licensed KTM mechanic.
Make sure the caps are screwed on tightly. Mount the muffler stress-free before
tightening the fixing screws.
The exhaust system becomes very hot while the motorcycle is running. to avoid
burns do not start work on the exhaust system until it has properly cooled
down.
