2-24 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Exhaust System Inspection
The exhaust system, in particular the muffler body, is de-
signed to reduce exhaust noise and conduct the exhaust
gases away from the rider while minimizing power loss. If
carbon has built up inside the muffler body, exhaust effi-
ciency is reduced, causing engine performance to drop.
If the muffler body is badly damaged, dented, cracked or
rusted, replace it. Replace the muffler baffle if the exhaust
noise becomes too loud or engine performance drops.
Muffler Baffle Change
Remove the muffler (see Muffler Removal in the Engine
Top End chapter).
Remove the muffler pipe mounting bolts [A].
Tap the bracket [A] of the muffler body with a plastic mallet
[B] to separate from the inner pipe.
Pull off the old muffler baffle assembly [A].
Install the new muffler baffle assembly [A] into the muffler
When replacing the muffler baffle assembly, first insert
the muffler baffle assembly into the muffler body, and
align the exhaust hole of the muffler body with the muf-
fler baffle assembly hole while turning the muffler baffle
assembly. Then, install the inner pipe by pushing the
inner pipe into the muffler body with aligning the inner
pipe with the exhaust hole.
Apply a non-permanent locking agent to the muffler pipe
Tighten the muffler pipe mounting bolts.
