Engine Type:
Air-cooled, four-stroke, OHV V-twin
Bore X Stroke:
Approximately 3.4375 in. x 4.25 in. (87.3 mm x 108 mm)
Compression Ratio:
Typically around 8.0:1 to 9.0:1 depending on specific model year and configuration.
Valvetrain:
Overhead Valve (OHV) with pushrod actuation
Horsepower Estimate:
Approximately 50-60 HP at rear wheel, depending on tuning and specific year.
Torque Estimate:
Around 60-70 lb-ft (81-95 Nm) at approximately 3000-4000 RPM.
Carburetor Type:
Often Linkert M-series or early Keihin butterfly carburetors.
Fuel Capacity:
Typically 3.5 to 4.0 US gallons (approx. 13-15 liters).
Oil Change:
Typically every 2,000-3,000 miles or annually, whichever comes first. Manual will specify exact interval and type.
Primary Chain Case Oil:
Check and change as per manual, often more frequently than engine oil.
Spark Plugs:
Inspect and replace as needed, typically every 5,000-10,000 miles.
Drive Chain:
Lubricate and adjust chain tension every 500-1,000 miles.
Engine Oil:
Manual will specify viscosity (e.g., 20W-50) and API service classification. Often a specific V-twin motorcycle oil is recommended.
Primary Chain Case Oil:
Manual will specify type, often a dedicated primary lubricant or HD-specific fluid.
Transmission Oil:
Manual will specify type and viscosity, often a heavier gear oil or HD-specific transmission fluid.
Brake Fluid:
If hydraulic brakes are present, manual will specify DOT rating (e.g., DOT 3 or DOT 4).
Engine Oil Leaks:
Common on older V-twins due to seal aging. Manual provides seal replacement procedures.
Carburetor Tuning:
Linkert carburetors can be finicky; proper adjustment is key for performance. Manual details tuning steps.
Electrical Reliability:
Aging wiring and components can lead to intermittent issues. Manual's wiring diagrams are critical.
Shovelhead Engine Characteristics:
Known for its distinctive sound and heat generation. Manual covers proper operation and maintenance to mitigate common wear.
Brand Legacy:
Harley-Davidson, founded in 1903, is an iconic American motorcycle manufacturer with a rich history of producing powerful, custom-inspired, and durable motorcycles.
Super Glide Origin:
The FX Super Glide, introduced in 1971 (for the 1971 model year), was designed by Willie G. Davidson. It featured a distinctive 'boat-tail' or 'eyebrow' rear section and a 'dogleg' front fork, intended to appeal to custom bike enthusiasts.
Fx Design:
The 'FX' designation historically indicated a blend of the 'FL' (more comfortable, often touring) and 'XL' (sportier, often Sportster) chassis components, creating a unique ride and handling characteristic.
Manufacturing Location:
Milwaukee, Wisconsin, USA
Production Period Context:
This period (1970-1978) saw significant styling and mechanical evolution for Harley-Davidson, including the introduction of the AMF era and the gradual refinement of the shovelhead engine and its associated components.
