Engine Manufacturer:
Arctic Cat (engine design based on Hisun partnership)
Engine Displacement:
641cc
Engine Configuration:
V-twin
Engine Cooling:
Liquid-cooled
Engine Valvetrain:
SOHC (Single Overhead Camshaft), 4 valves per cylinder (typical for this engine)
Bore X Stroke:
Specifics typically found in the manual, but commonly around 80mm x 64mm for this engine displacement.
Horsepower Estimate:
Approximately 45-50 HP (manufacturer figures vary, this is a common estimate for this class)
Torque Estimate:
Approximately 35-40 ft-lbs (estimated)
Fuel Delivery:
Likely Carbureted (Mikuni 36mm twin carburetors common on this model/year), though some markets might have had EFI options. Manual would detail the specific system.
Fuel Type:
Unleaded gasoline (87 octane recommended)
Engine Oil Change:
Every 100 hours or annually, whichever comes first. Manual will provide exact interval based on usage type.
Air Filter Cleaning:
Inspect every 50 hours, clean/replace as needed. More frequent cleaning in dusty conditions. Manual details specific cleaning procedures.
Spark Plug Replacement:
Typically every 200-300 hours or as recommended by the manual. Manual will specify part number and gap.
Cv Belt Inspection:
Inspect for wear and damage every 50-100 hours. Replace as needed. Manual details inspection procedure.
Engine Oil Type:
Arctic Cat recommends specific API SG or higher, SAE 10W-40 synthetic or semi-synthetic engine oil. Manual will list exact specification and capacity.
Coolant Type:
