Replacing The Glass Fiber Yarn Packing Of The Silencer - KTM SUPERMOTO FACTORY REPLICA 660SMS 2004 Owner's Manual

Replacing the glass fiber yarn packing of the silencer *

The silencer is filled with glass-fiber yarn to reduce the noise. The effect of
heat causes the glass fiber yarn to become loose. This may lead to a loss of
performance and reduce the silencer's muffling power.
To replace the glass-fiber yarn, remove the silencer. Bore out all 8 rivets and
disassemble the silencer. Clean parts and check for cracks.
For easy mounting of the glass-fiber yarn pack, wrap fabric tape around the
1
rear end of the exhaust pipe . Slide the glass-fiber yarn pack onto the
exhaust pipe. Mount the outer pipe and fix in the front with 4 rivets. Center
the exhaust pipe. Mount the end cap and the rivets.
