Horsepower Torque General:
Specific horsepower and torque figures vary between the 400 H.O. and 500 H.O. models. The 500 H.O. generally produces more power and torque, suitable for heavier loads and more demanding terrain. This manual will contain precise specifications.
Compression Ratio:
Specific compression ratios for both engine variants will be detailed in the manual, crucial for diagnosing engine health.
Fuel Delivery:
Likely utilizes a fuel injection (EFI) system for optimal fuel/air mixture control, particularly for the 'EFI' variant mentioned, and potentially for all 2012 models for emissions and performance benefits. Carbureted models might still exist in some international markets, but EFI is prevalent for this era.
Fuel Type:
Unleaded gasoline.
Efi System Components:
Includes details on throttle body, fuel pump, fuel filter, fuel injectors, and ECU (Engine Control Unit) for EFI models.
Atv Platform Dimensions:
Dimensions vary slightly between 400 and 500 models and touring vs. standard configurations. Typical Sportsman dimensions are around 83-85 inches in length, 46-48 inches in width, and 47-50 inches in height. The manual will provide exact chassis dimensions.
