Engine Type 300:
Likely a 2-stroke, single-cylinder engine (specific displacement: ~299cc). Common for the era and model name.
Engine Type 400:
Likely a 2-stroke, single-cylinder engine (specific displacement: ~375-400cc). Common for the era and model name.
Estimated Horsepower 300:
Approximately 18-22 HP (typical for 300cc class 2-stroke ATVs of this period).
Estimated Horsepower 400:
Approximately 22-28 HP (typical for 400cc class 2-stroke ATVs of this period).
Carburetor Type:
Likely a Mikuni VM series or similar single carburetor with automatic choke.
Fuel Type:
Unleaded gasoline, typically requires a mix with 2-stroke oil for lubrication (oil injection system or premix).
Cooling Method:
Liquid-cooled (typical for Polaris models of this era for better performance and reliability).
Transmission Type:
Automatic (CVT - Continuously Variable Transmission) with forward, neutral, and reverse gears.
Optional Transmissions:
N/A (CVT was standard for this model class).
Drive System:
2WD (Rear Wheel Drive) is most common for the Xpress line of this era. Some later models might have offered 4WD, but the Xpress was primarily a recreational 2WD unit.
Clutch Type:
Primary and secondary clutch (CVT) with a drive belt.
Transmission Fluid:
Specific CVT fluid (e.g., Polaris Angle Drive Fluid or equivalent) is required for the transmission and final drive.
Length:
Approx. 70-75 inches (typical for this class).
Width:
Approx. 40-45 inches (typical for this class).
Height:
Approx. 45-50 inches (typical for this class).
Dry Weight:
Approx. 400-450 lbs (typical for this class).
Ground Clearance:
Approx. 5-7 inches (typical for this class).
Rack Capacity:
Front and rear racks with estimated capacity of ~50-75 lbs each.
Engine Oil Change:
Typically every 20-40 operating hours or annually, depending on usage severity.
Spark Plug Inspection:
Inspect every 20 operating hours, replace as needed.
Air Filter Cleaning:
Clean every 10-20 operating hours, replace when damaged.
Cv Belt Inspection:
Inspect every 40-60 operating hours for wear, cracks, or glazing. Replace if any signs of damage are present.
Engine Oil Type 300:
Polaris Premium 2-Cycle Oil or equivalent API TC-W3 rated oil (for premix) or specific Polaris 2-stroke oil injection fluid.
Engine Oil Type 400:
Polaris Premium 2-Cycle Oil or equivalent API TC-W3 rated oil (for premix) or specific Polaris 2-stroke oil injection fluid.
Transmission Fluid Type:
Polaris Angle Drive Fluid or equivalent SAE 80W-90 GL-4 gear oil (confirm with manual for specific final drive).
