Bore X Stroke:
Varies by specific model. For example, Kz550: 66.0 mm x 81.0 mm (approx.).
Compression Ratio:
Typically around 9.0:1 to 10.0:1 depending on the specific model and tuning.
Horsepower Range:
Estimated 48-60 HP at the crankshaft, depending on the specific model and state of tune.
Torque Range:
Estimated 28-35 lb-ft, depending on the specific model.
Carburetion:
Typically dual Mikuni VM or BS series carburetors (e.g., VM26, BS30).
Fuel Type:

Oil Change Interval:
Typically every 3,000-6,000 miles or annually, depending on riding conditions. Consult manual for specific recommendations.
Valve Adjustment Interval:
Usually around 6,000-12,000 miles. Precision is critical for performance and longevity.
Chain Lubrication And Adjustment:
Regularly, every 500-1000 miles and after washing or riding in wet conditions.
Engine Oil Type:
API SE, SF, or SG classification, SAE 10W-40 or 20W-50 motorcycle specific oil is generally recommended. Always verify with the manual.
Engine Oil Capacity:
Approximately 2.5 - 3.0 liters (with filter change), specific capacity detailed in the manual.
Brake Fluid Type:
DOT 3 or DOT 4 (check master cylinder cap for specification). Always use fresh, high-quality fluid.
Fork Oil Type:
Typically SAE 10W or 15W fork oil. Specific viscosity and quantity are crucial for correct damping.
Carburetor Issues:
Gumming and clogging of carburetors due to fuel degradation over time, requiring cleaning and synchronization.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical issues. Regulator/rectifier failures are also common on bikes of this age.
Suspension Wear:
Fork seals can leak, and rear shock absorbers may lose damping effectiveness over time.
Engine Seals:
Age-related degradation of engine and transmission seals can lead to oil leaks.
Spark Plug Type:
Commonly NGK or Denso plugs, e.g., NGK CR9E or similar. Specific type and gap are detailed in the manual.
Valve Clearance Intake:
Typically a small clearance, e.g., 0.05-0.10 mm. Exact figures are model-specific.
Valve Clearance Exhaust:
Typically a small clearance, e.g., 0.05-0.10 mm. Exact figures are model-specific.
Tire Pressure Front:
Typically 28-32 PSI (cold). Check sidewall for recommendations.
Tire Pressure Rear:
Typically 32-36 PSI (cold). Check sidewall for recommendations.
