Section 8
8.) Exhaust systems:
Considerable effort has gone into the design of the ROT AX exhaust systems. Any changes may
severely deteriorate performance, reliability, engine life, fuel economy, and the system's ability to
reduce noise to acceptable levels. Do not use other exhaust systems claimed to improve over the stock
components. Do not make any changes to the exhaust system supplied.
•
Vibration due to
improper
suspension is any exhaust system's worst enemy. Properly mounted and
maintained, your
exhaust
system
will provide a long service life.
.•.
Never remove coupling spring with a sharp object which could mark the spring material. A rounded
screw-driver shank or a hook fashioned from 1/8" bar is
ideal.
Safety-wiring of springs is highly re-
commended.
Exhaust ball sockets should be kept lubricated by a heat resistant grease to allow for
movement between engine and
muffler.
