MAINTENANCE
Exhaust System
Check the exhaust system for wear or damage at approximately 2000
miles (3200 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.
Variable Exhaust System (VES)
Maintenance of the VES is limited to a periodic inspection and cleaning
of system components. Every 1000 to 2000 miles (800-1600 km), bring
the machine to an authorized Polaris dealer to have the VES disassem-
bled, inspected, and cleaned.
NOTE: To ensure maximum performance and minimize required main-
tenance, follow the oil recommendation chart on page 58. The
use of other lubricants may cause improper function of the
valve mechanism and increase the frequency of required
cleaning due to excessive build-up of carbon deposits.
WARNING
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.
