Engine Type:
2-stroke, liquid-cooled, single-cylinder
Displacement:
398cc (approximately)
Bore X Stroke:
Typically around 80mm x 79mm (specifics in manual)
Compression Ratio:
Typically 6.5:1 to 7.0:1 (specifics in manual)
Horsepower:
Estimated 28-32 HP (specifics in manual)
Torque:
Estimated 28-32 lb-ft (specifics in manual)
Carburetor Model:
Likely Mikuni VM34 or similar
Fuel Type:
Unleaded gasoline (87 octane or higher)
Fuel Mixture:
Requires 2-stroke oil mixed with gasoline (ratio specified in manual, typically 40:1 or 50:1)
2 Stroke Oil Type:
High-quality 2-stroke engine oil (e.g., JASO FD rated)
Engine Oil Change:
Typically every 50-100 operating hours or annually (specifics in manual)
Air Filter Cleaning:
Every 20-40 operating hours or as needed based on conditions (specifics in manual)
