Engine Type:
Air-cooled, four-stroke, 45-degree V-twin
Engine Displacement:
1200 cc (approx. 74 cubic inches)
Engine Designation:
Shovelhead (referring to the distinctive shape of the rocker boxes)
Bore X Stroke:
Typically 3.4375 in. x 4.25 in. (87.3 mm x 108 mm). Manual will confirm exact figures.
Horsepower Range:
Typically 50-65 HP, depending on specific year and tuning. Exact figures vary.
Torque Output:
Strong low-end torque, characteristic of Harley-Davidson V-twins. Specific figures depend on variant and year.
Compression Ratio:
Varies by year and model, generally between 7:1 and 9:1. Manual will provide specific data.
Carburetor Types:
Primarily Keihin butterfly (CV) carburetors from the mid-70s onwards, and earlier models may feature Linkert or other configurations. The manual will detail their service and adjustment.
Fuel Type Recommendation:
Leaded or unleaded gasoline, depending on engine compression and valve seat material (manual will specify).
Oil System Type:
Dry sump lubrication system with oil tank typically located in the crankcase or frame.
Oil Capacity:
Approximately 3-4 quarts (3-4 liters) including oil tank. Manual will provide exact figures and filter part numbers.
Ignition System:
Contact breaker points ignition system. Manual will cover timing, adjustment, and replacement of points and condenser.

Gearbox Oil Type:
Manual will specify appropriate gear oil viscosity and type (e.g., 85W-140 gear oil or Harley-Davidson specific lubricant).
Safety Standards Era:
Safety standards for this era were less stringent than modern motorcycles. The manual will detail mechanical safety checks and adjustments.

Significant tune-ups, valve adjustments, and inspections often recommended every 5,000-10,000 miles (8,000-16,000 km).
Engine Oil Type:
Manual will specify appropriate Harley-Davidson approved motorcycle oil, typically a 20W-50 or 30W for air-cooled V-twins of this era, potentially with specific additives.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid, depending on the specific brake system components used in a given year and model. Manual will specify.
Primary Chain Case Fluid:
Manual will detail the correct lubricant for the primary chaincase, often a dedicated primary lubricant or transmission fluid (e.g., Type 'F' or similar, depending on transmission design).
Fork Oil Type:
Manual will specify appropriate fork oil viscosity and quantity for the front suspension. Harley-Davidson often recommended specific fork oils or a blend.
Common Wear Items:
Valve guides, piston rings, lifters, cam followers, and oil leaks (common with older V-twins). Clutch wear and primary chain adjustment are also critical.
Electrical Component Reliability:
Voltage regulators, ignition coils, and wiring harness integrity can be points of concern. Manual provides diagnostic procedures.
Carburetor Issues:
Float bowl leaks, worn throttle shafts, and jetting issues can lead to poor running. Keihin CV carburetors require careful adjustment of the diaphragm and needle.
Engine Fasteners Torque:
Specific torque values for critical engine fasteners such as cylinder head bolts, crankcase bolts, and rocker box bolts will be detailed in the manual.
Wheel And Axle Torque:

Harley Davidson Legacy:
Harley-Davidson, founded in 1903, is an iconic American motorcycle manufacturer with a rich history of producing large-displacement V-twin motorcycles known for their torque, sound, and distinctive styling.
Shovelhead Era:
The 1970-1980 period covers the 'Shovelhead' engine era for Harley-Davidson's big twins, a significant evolutionary step from the Panhead engine. These models represent a blend of classic styling and performance for their time.
Electra Glide Role:
The Electra Glide, introduced in the 1960s, became Harley-Davidson's premier touring motorcycle, featuring large fairings, saddlebags, and comfortable seating.
Super Glide Role:
The Super Glide, introduced in the early 1970s, offered a more stripped-down, performance-oriented riding experience compared to the Electra Glide, often featuring custom styling cues.
