Exhaust systems:
Considerable
effort has
gone
into the
design of the
ROTAX
exhaust
systems. Any
changes may
seveEly detedonte
performance,
rcliability, engine life, fuel economy,
and the system's
ability to
reduce
noise
to acceptable
levels.
Do not use other exhaust
systems clairrd to improve
over the stock
components. Do
not
make any changes to the exhaust system supplied.
Vibotiou due to
imprcper
suspcnsion is
any
exhaust
system's wont enemy,
Prcperly mounted
and
maintained,
your
exhaust system will
provide
a
long
service life.
Never
remove
coupling spring
with
a sharp object which could Dtark
the spriDg material.
A rounded
scrcw-driver shank
or a hook fashioned froDl 1/8"
bar
is
idea.l. Safety-widng
of springs is highly
re-
cornmended. Exhaust ball sockets should be kepr lubdcated
by a heat Fsistaot
grease
to allow for
movement belween ensine and nuffler.
