Engine Type:
Air-cooled, 4-stroke, SOHC, V-twin
Displacement:
1602 cc (97.7 cubic inches)
Bore X Stroke:
95.0 mm x 113.0 mm
Compression Ratio:
8.0:1 (typical for this engine)
Horsepower:
Approx. 63 hp @ 4000 rpm (variant dependent)
Torque:
Approx. 97 lb-ft (131 Nm) @ 2700 rpm (variant dependent)
Carburetion:
Twin VM-type carburetors (likely 37mm or similar, specific size in manual)
Fuel Type:
Unleaded gasoline (minimum 87 octane recommended)
Oil Capacity:
Approx. 4.2 Liters (4.4 US qts) with filter change (verify in manual)
Oil Type Recommendation:
Yamalube 4 (or equivalent SAE 20W-40 motorcycle oil, verify spec in manual)
Oil Change:
Every 5,000 km (3,000 miles) or 6 months, whichever comes first (typical recommendation, verify in manual).
Air Filter Check:
Every 5,000 km (3,000 miles) or annually.
Spark Plug Check:
Every 10,000 km (6,000 miles).
Valve Clearance Check:
Every 20,000 km (12,000 miles) or as specified in manual.
Belt Tension Check:
Every 5,000 km (3,000 miles) or annually.
Engine Oil Grade:
SAE 20W-40 (Yamalube 4 recommended, verify in manual)
Brake Fluid Type:
DOT 3 or DOT 4 (verify in manual)
Final Drive Oil:
Hypoid gear oil SAE 80 or 90 (verify in manual)
Common Issues:
Carburetor synchronization may require periodic adjustment. Belt drive requires proper tensioning to prevent premature wear. Some owners report regulator/rectifier failures over time. Starter drive gear wear can occur if the starter button is held too long after the engine starts.
Preventative Maintenance Focus:
Regular inspection and proper lubrication of the belt drive, timely oil changes, and checking electrical connections are crucial for longevity.
