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 af-
fect 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

saddle, screws (1) andR.H. side panel (2). Remove the two ex-
haust silencer fastening screws (3). Extract the silencer from
the union manifold to the

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.
