Valvetrain:
SOHC (Single Overhead Camshaft) or DOHC (Double Overhead Camshaft) depending on specific model year and variant; 2 valves per cylinder common for earlier models, some later models may have had 4 valves.
Bore X Stroke:
Varies by displacement. E.g., XV750 often around 83mm x 68mm, XV1100 around 95mm x 75mm.
Compression Ratio:
Typically in the range of 8.5:1 to 9.5:1.
Typical Horsepower Range:
Approximately 45-65 HP, varying by displacement and year.
Typical Torque Range:
Approximately 45-60 lb-ft, varying by displacement and year.
Fuel Delivery System:
Carburetor(s) (e.g., Mikuni constant velocity carbs) for most models; some later or specific market variants may have featured fuel injection.
Fuel Type:
Unleaded gasoline
Oil Change Interval:
Typically every 3,000-5,000 miles or 6 months, whichever comes first (refer to manual for exact specification).
Spark Plug Replacement Interval:
Approximately every 10,000-15,000 miles (depending on spark plug type).
Valve Clearance Adjustment:
Typically at 10,000-15,000 mile intervals, or as per manual recommendation.
Engine Oil Type:
API SG or higher, SAE 10W-40 or 20W-50 motorcycle-specific oil is commonly recommended.
Brake Fluid Type:
DOT 3 or DOT 4, depending on the specific model year and original specification.
Final Drive Oil Type:
Hypoid gear oil, SAE 80W-90 API GL-5 is typical for shaft drives.
Engine Oil Capacity:
Varies by model, typically around 2.5-3.0 liters (approx. 2.6-3.2 US quarts) including filter. Exact capacity must be confirmed in the manual.
Transmission Oil Capacity:
Not typically a separate fill; engine oil lubricates the transmission.
Final Drive Oil Capacity:
Typically around 0.1-0.2 liters. Exact capacity must be confirmed in the manual.
Common Wear Items:
Carburetor diaphrams (especially on CV carbs), regulator/rectifier units, brake components (pads, seals), fork seals, drive shaft splines (lubrication is key).
Electrical Gremlins:
Corrosion in connectors, failing stator or rotor on higher mileage units.
Carburetor Performance:
Varnishing and clogging of jets over time due to fuel degradation, leading to poor idling and running.
Yamaha Motorcycles:
Yamaha has a long and storied history in motorcycle manufacturing, known for innovation, performance, and reliability across various segments.
Virago Line Introduction:
The Virago line was introduced in the early 1980s, establishing Yamaha as a strong contender in the cruiser market. The XV700 was initially released due to US import restrictions on larger displacement motorcycles, later followed by 750cc, 1000cc, and 1100cc variants.
Production Period:
1981-1999
Manufacturing Location:
Japan (primary manufacturing for Yamaha vehicles)
