General Maintenance
Exhaust System
Check the exhaust system for wear or damage at approximately 1000
miles (1600 km). To inspect, allow the engine and exhaust system to
cool completely. Open the hood and inspect the muffler and pipes for
cracks or damage. Check for weak or missing retaining springs or
damper/support grommets.
Engine Cooling - Liquid Cooled Models
The cooling system on liquid cooled models consists of the following
major components:
S
Coolant bottle
S
Water pump
S
Cylinders
S
Heads
S
Inlet and outlet manifolds
S
Pressure cap
S
Heat exchangers
Coolant Mixture
The coolant supplied in the system is a 50/50 mixture of
ethylene-glycol and distilled water. This mixture provides protection
against freezing at temperatures to -34° F (-37° C). If greater
protection is required, the percentage of antifreeze to water may be
increased. Use Premium 60/40 anti-freeze coolant, which is already
premixed and ready to use. Do not dilute with water. Never exceed a
60% antifreeze/40% water mixture. Contact you dealer if greater
protection is required.
NOTE: Never add tap water to the cooling system. Minerals cause
deposits and may react adversely with the metals in the engine and
cooling system.
Hot exhaust system parts can cause serious burns. Allow
adequate time for the exhaust system to cool. Never perform
this procedure with the engine running.
