Exhaust Muffler - Husqvarna WR 250 2011 Manual De Uso Y Mantenimiento

EXHAUST MUFFLER

The muffler reduces the noise of the exhaust gases, but it is an
integral part of the exhaust as well. As such, its conditions affect
the motorcycle performance.
When the noise on the exhaust is too high, it means that the
deadening material set on the holed tube inside the muffler
is deteriorated.
WARNING: Check the deadening material af-
ter every competition and replace it if neces-
sary.
REPLACING MUFFLER DEADENING MATERIAL
First turn counterclockwise fastening rear pin (A) then remo-
ve saddle, screws (1) andR.H. side panel (2). Remove the two
exhaust silencer fastening screws (3). Extract the silencer from
the union manifold to the
exhaust pipe. Remove the screws (4), the inner tube (5) and
replace the old silencer packing. Check the
O-Ring (6) for wear and replace it, if necessary. Cheek the ma-
nifold (7) for wear and replace it, if necessary.
Note*: If silencer or exhaust are difficult to
remove, help to slide them apart by tapping
gently with a rubber or plastic hammer.
