Initial Break In:
Specific break-in procedure outlined in the owner's manual and detailed in the service manual, typically involving varied RPMs and gentle operation for the first ~500 miles/10 hours.
Oil Change Engine:
2-stroke engines do not have oil changes in the traditional sense; oil is consumed via injection. Monitor oil injection system and ensure oil reservoir is topped up.
Clutch Maintenance:
Inspect primary and secondary clutches every 50-100 hours or annually for wear on rollers, buttons, springs, and helix. Clean sheaves.
Chaincase Oil Change:
Every 100 hours or annually. Check for leaks or contamination.
Spark Plug Replacement:
Inspect every 50-100 hours, replace as needed. Recommended plug type often NGK BR9ES or equivalent.
Coolant:
Ethylene glycol-based antifreeze. 50/50 mix with distilled water. Capacity typically 1.5-2.0 quarts.
Brake Fluid:
DOT 4 hydraulic brake fluid.
2 Stroke Oil:
Polaris VES (Variable Exhaust System) Synthetic 2-Stroke Oil or equivalent API TC-W3 certified oil.
Common Wear Items:
Clutch bushings/rollers, shock absorber seals, track drivers, hyfax (slider wear), and carbide wear bars on skis.
Engine Specific:
Potential for crank seal leaks on high-mileage units, exhaust valve maintenance (cleaning and lubrication for VES system), and proper jetting for altitude/temperature changes.
Polaris Legacy:
Polaris has a long history in snowmobiling, dating back to the 1950s, known for innovation and performance-oriented machines.
Rmk Lineage:
The RMK (Ranger Mountain Kayak) line has been a cornerstone of Polaris's mountain segment, evolving through chassis and engine advancements to meet the demands of backcountry riding.
2009 Specifics:
The 2009 models benefited from chassis improvements focusing on weight reduction and improved handling, with the 'Shift' model introducing adjustable front suspension geometry for fine-tuning ride height and roll center.
Manufacturing Location:
Roseau, Minnesota, USA (Polaris's primary snowmobile manufacturing facility)
