Engine Type:
V-twin cylinder, 4-stroke
Engine Displacement:
1096 cc (for XV1100 models, though '1981' and 'XV1100' might indicate an early or representative specification; actual 1100cc models appeared later, so the '1981' designation might be a slight anomaly for an '1100' model, or represent an early prototype/variant designation).
Horsepower Estimate:
Approx. 65-70 HP (typical for this engine class and era, though specific 1981 XV1100 data is scarce and may refer to development or a less common variant; standard XV1100 models typically produced around 64 HP).
Carburetion:
Dual Mikuni carburetors (likely 35mm or similar, specific details within the manual)
Fuel Delivery:
Gravity feed with vacuum-operated petcock
Oil Change Interval:
Typically every 3,000-5,000 miles or annually (specific details in manual)
Spark Plug Replacement:
Recommended replacement at 10,000-15,000 mile intervals (specifics in manual)
Engine Oil Type:
Yamalube 20W-40 API SE or SF (or equivalent motorcycle-specific oil, manual will provide exact specs)
Engine Oil Capacity:
Approx. 3.2 liters (with filter change, manual will confirm)
Brake Fluid Type:
DOT 3 or DOT 4 (manual will specify)
Coolant Type:
If liquid-cooled, specified coolant mix (XV1100 is air-cooled, so this would not apply to the engine itself but potentially other systems if present).
Carburetor Issues:
Carburetor synchronization and cleaning often required for smooth running.
Electrical Connections:
Corrosion or loosening of electrical connectors can lead to intermittent issues.
Fuel Delivery Problems:
Clogged fuel filters or issues with the petcock can affect fuel flow.
Driveshaft Boot Wear:
Wear on the driveshaft boot can lead to lubrication loss and component damage.
Yamaha Legacy:
Yamaha's history in motorcycle manufacturing, known for innovation and performance.
Virago Lineage:
The Virago line was Yamaha's entry into the cruiser market, known for its stylish V-twin engines and custom looks. The XV1100 specifically was a significant iteration.
Initial Release Period:
The XV1100 Virago was primarily produced from the mid-1980s onwards, with the '1981' designation for this manual potentially referring to an early development phase or a specific regional/prototype model.
