Sportsman 400 HO: Approximately 375cc to 400cc (estimated, actual '400' designation might refer to a range or specific engine variant). Bore X Stroke: Not explicitly provided, but standard specifications for these engine displacements would be detailed within the manual. Compression Ratio: Not explicitly provided, but would be detailed within the manual. Performance Horsepower: Not explicitly provided. Typical outputs for these displacements range from 20-30 HP for the 300cc class and 25-35 HP for the 400cc class. Torque: Not explicitly provided. Torque specifications and curves would be available in the manual. Fuel System Fuel Delivery: Electronic Fuel Injection (EFI). Specific injector types and pressure specifications would be covered. Fuel Type: Unleaded gasoline (Octane rating specification would be in the manual). Fuel Tank Capacity: Typically around 3.2 to 3.7 gallons for this class of Polaris ATV, specific capacity would be in the manual. Lubrication Oil Type: Polaris branded or equivalent synthetic ATV engine oil (e.g., SAE 5W-50 or 10W-40, depending on climate) meeting specific API or JASO standards. Specific part numbers and viscosity grades would be detailed. Oil Capacity: Approximately 1.5 to 2.0 quarts (1.4 to 1.9 liters) without filter change, and slightly more with filter. Exact capacity with and without filter change will be in the manual. Oil Filter Part Number: Likely Polaris part number 3086703 or similar for this era. Specific part numbers for both models and engine options will be confirmed in the manual. Cooling System Cooling Type: Liquid-cooled Coolant Type: Ethylene glycol based antifreeze, typically a 50/50 mix with de-ionized water. Specific color and type (e.g., Asian vehicle formula) might be recommended. Capacity and bleeding procedures would be detailed. 🔧 Transmission Standard Transmission Type: Automatic Polaris Variable Transmission (PVT) with engine braking. Drive Modes: On-Demand All-Wheel Drive (AWD) with 2WD/AWD selector, and VersaTrac™ differential lock. Gear Selection: High (H), Low (L), Neutral (N), Reverse (R), Park (P). Features Clutch Type: Primary and Secondary clutch system for the PVT. Belt condition and replacement intervals are critical maintenance items detailed in the manual. Drive Chain Sprockets: The manual will cover inspection, adjustment, and replacement of drive chains and sprockets where applicable (though many Polaris ATVs of this era use shaft drive or belt drive systems primarily). The 'Drive Chain & Sprockets' section suggests this is relevant. Fluid Specifications Transmission Fluid Type: Typically SAE 10W-40 or 20W-50 Synthetic Gearcase Lubricant, or specific Polaris AGL (All-Season Gearcase Lubricant) fluid.
