Diagnostic Capability:
Advanced diagnostic procedures for identifying root causes of problems.
Engine Manufacturer:
Arctic Cat (likely sourced from a third party like Rotax or Suzuki for the core engine, but serviced by Arctic Cat specs).
Engine Displacement:
Approximately 375-400cc (specific displacement not provided, but '400' in the model name is indicative).
Engine Type:
Likely a single-cylinder, four-stroke, liquid-cooled engine.
Engine Configuration:
SOHC (Single Overhead Camshaft) with 2 or 4 valves per cylinder is probable.
Horsepower:
Estimated 25-30 HP (typical for this class).
Torque:
Estimated 28-32 lb-ft (typical for this class).
Fuel Delivery:
Carbureted (likely Keihin CVK 36 or similar) or potentially electronic fuel injection (EFI) depending on specific sub-model, though carburetors were more common at this displacement for 2011.
Fuel Type:
Unleaded gasoline, 87 octane recommended.
Coolant Type:
Ethylene glycol based antifreeze coolant (e.g., SAE J1941 compliant).
Coolant Capacity:
Approximately 1.5 - 2.0 liters (specific value to be found in manual).
Rollover Resistance:
ATVs are inherently prone to rollovers; proper training and adherence to safe operating practices are crucial.
Braking System:
Hydraulic disc brakes front and rear.
4Wd Engagement:
Provides enhanced traction in challenging terrain.
Curtain Shield Air Bag Assy:
N/A - Airbags are not a standard feature on ATVs of this era.
Throttle Governor:
May be present to limit top speed, especially on certain models or configurations.
Operator Training:
Crucial for safe operation; manual emphasizes safe riding practices and protective gear.
Oil Change Interval:
Typically every 100-200 operating hours or annually, whichever comes first. Check manual for exact hours/months.
Air Filter Cleaning:
Inspect every 20-40 operating hours, clean or replace as needed.
Spark Plug Check:
Inspect every 50-100 operating hours, replace as needed.
Drive Belt Inspection:
Inspect every 50 operating hours for wear and damage, replace as recommended by wear indicators.
Engine Oil Type:
SAE 10W-40 motorcycle/ATV specific oil, API SG or higher, JASO MA certified. (Refer to manual for exact specification).
Engine Oil Capacity:
Approximately 1.5 - 1.8 liters (check manual for exact capacity).
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Gearcase Oil Type:
Specific gear oil for differentials (e.g., SAE 80W-90 GL-5 or Arctic Cat branded fluid).
Common Wear Items:
CVT belt, wheel bearings, tie rod ends, brake pads, and suspension bushings are common wear items on ATVs of this age and usage.
Carburetor Issues:
Carburetors can become clogged with ethanol-affected fuel or debris, leading to poor running conditions.
