Engine Type:
Air-cooled, V-twin, OHV (Overhead Valve)
Engine Displacement:
74 cubic inches (1213 cc)
Bore X Stroke:
3.4375 in x 4.25 in (87.3 mm x 108 mm)
Compression Ratio:
Approx. 7.0:1 to 8.0:1 (depending on specific variant and tuning)
Horsepower:
Estimated 50-60 HP (at the crankshaft, not wheel) - specific figures varied.
Torque:
Estimated 65-75 lb-ft - specific figures varied.
Carburetor:
Keihin butterfly or Linkert (early models), then likely replaced by later Keihin or Mikuni in some aftermarket scenarios, but factory spec was typically Keihin.
Fuel Type:
Unleaded gasoline (with appropriate octane rating, often 87-91 RON or equivalent).
Oil System:
Dry sump lubrication system (oil tank separate from engine crankcase).
Oil Type:
Harley-Davidson recommends specific motorcycle-grade oil (e.g., SAE 20W50, or equivalent for vintage bikes). Avoid modern car oils with friction modifiers.
Ignition Type:
Contact breaker points, ignition coil, distributor (if applicable, usually separate from ignition module), spark plugs.
Wheelbase:
Approx. 62.5 inches (1588 mm) - can vary slightly with fork rake.
Overall Length:
Approx. 90-95 inches (2286-2413 mm)
Dry Weight:
Approx. 600-650 lbs (272-295 kg), depending on model and accessories.
Gross Vehicle Weight Rating:
Not typically specified for motorcycles in the same way as cars, but relates to rider, passenger, and cargo capacity.
Oil Change:
Typically every 2,000-3,000 miles (3,200-4,800 km) or annually, whichever comes first. Check manual for exact specification.
Filter Replacement:
Oil filter: Replace at every oil change. Air filter: Inspect regularly, replace as needed.
Spark Plugs:
Inspect every 3,000-5,000 miles (4,800-8,000 km), replace as needed. Common plugs were Champion or AC.
Chain Adjustment:
Check and adjust drive chain slack every 1,000 miles (1,600 km) or as needed. Specified slack is typically 0.5-0.75 inches.
Engine Oil Capacity:
Approx. 3 quarts (2.8 liters) for the engine and oil tank combined. Exact capacity to be verified in manual.
Transmission Fluid Capacity:
Approx. 1 pint (0.47 liters). Verify in manual.
Brake Fluid:
If equipped with disc brake: DOT 3 or DOT 4 hydraulic brake fluid (check manual for specific type). Drum brakes do not require fluid.
Fork Oil Type:
Specific type and viscosity of fork oil will be detailed in the manual, typically a light-weight hydraulic fluid.
Common Problems:
Oil leaks (pan gasket, pushrod tubes, primary cover), primary chain adjustment issues, generator output, carburetor tuning, clutch drag, wear in suspension bushings, points ignition timing drift.
Carburetor Tuning:
Keihin butterfly carburetors can be finicky and require precise adjustment for optimal performance. Linkert carbs are known for their simplicity but can be prone to wear. Manual provides detailed tuning procedures.
Electrical System:
Early generator systems can sometimes have output issues. Wiring harnesses can degrade over time. Manual provides detailed troubleshooting and wiring diagrams.
Heritage:
Harley-Davidson, an iconic American motorcycle manufacturer founded in 1903, known for its V-twin engines and long-distance touring motorcycles.
Evolution:
The Electra Glide and Super Glide lines represent Harley-Davidson's flagship large touring motorcycles, evolving from earlier FL models. The 1970-1972 era saw the introduction of significant updates including the electric starter becoming more common and advancements in braking systems.
Key Advancements 70S:
The early 70s saw Harley-Davidson transitioning towards more user-friendly features like electric starters becoming standard on many models, improved braking systems (disc brakes appearing on some), and continued refinement of the Shovelhead engine architecture (though the '70-'72 bikes often still carried Shovelhead aspects from the later 60s).
Production Years:
Electra Glide and Super Glide models have been in continuous production in various forms since the 1960s.
Manufacturing Location:
Milwaukee, Wisconsin, USA.
