Typical Horsepower Range:
Ranges from approximately 100 HP to 150+ HP, depending on the specific engine displacement and model year.
Injection Type:
Primarily Electronic Fuel Injection (EFI) with throttle body injection (TBI) or multi-point injection (MPI) depending on engine. Carbureted models may be present in early years or specific configurations.
Ignition Control:
Digital CDI with electronic timing control.
Oil Type:
Likely SAE 0W-40 or 5W-40 synthetic 4-stroke engine oil. Specific Polaris-branded or API certified oils recommended. (Consult manual for exact specifications).
Transmission Type:
CVT (Continuously Variable Transmission) system utilizing a P85/P90 primary clutch and an AD/ADL/ACK secondary clutch assembly, depending on model and year.
Optional Transmission:
N/A (CVT was standard for 4-stroke models in this era).
Clutch Maintenance:
Detailed procedures for clutch inspection, belt replacement, spring and weight adjustments, and sheave maintenance.
Chaincase Lubrication:
Specifications for chaincase oil type and change intervals, along with inspection of drive chains and sprockets.
Instrumentation:
Digital/analog instrument clusters displaying speed, RPM, fuel level, engine temperature, and diagnostic indicator lights. Some models may feature basic LCD displays.
Rider Aids:
Reverse gear (on many models), hand and thumb warmers, electric start, and integrated lighting systems.
Diagnostic Ports:
Diagnostic connectors for use with specialized Polaris diagnostic tools (e.g., Digital Wrench) for reading fault codes and performing system checks.
Oil Change Interval:
Typically every 1,000 miles or annually, whichever comes first. (Refer to manual for precise mileage/hours and specific engine types).
Clutch Service Interval:
Inspection recommended annually or every 1,000 miles. Belt replacement based on wear or failure.
Spark Plug Replacement:
Typically every 2,000-3,000 miles or as specified by Polaris.
Coolant Type:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Polaris recommends specific coolant formulations. (Verify in manual).
Chaincase Oil:
Specific gear oil or chaincase lubricant recommended by Polaris. (e.g., Polaris Synthetic Gearcase Lube).
Common Wear Items:
CVT belt wear, shock absorber seal leaks, track tension adjustments, and potential ECU firmware updates for engine performance and emissions.
Potential Failures:
Inconsistent fuel delivery due to injector clogging, voltage regulator failures, and occasional primary clutch bearing issues, depending on usage and maintenance.
Heritage:
Polaris Industries Inc. has a long history in motorsports, particularly with snowmobiles, dating back to the 1950s. They are known for innovation and performance in the segment.
Evolution 2006-2014:
