Engine Family:
Shovelhead (evolution of the Panhead design, characterized by its 'shovel' shaped rocker boxes)
Displacement:
74 cubic inches (1211 cc)
Bore X Stroke:
3.4375 in x 4.25 in (87.3 mm x 108 mm)
Compression Ratio:
Approximately 8.0:1 (stock)
Horsepower:
Estimated 60-65 HP (at crank, stock)
Torque:
Estimated 70-75 ft-lbs (at crank, stock)
Carburetor Type:
Likely a Keihin butterfly carburetor (e.g., CV or Linkert on earlier models, though 1980 would be post-Linkert transition)
Fuel Requirement:
Unleaded gasoline, typically 87 octane (AKI) or higher
Transmission Type:
4-speed constant mesh, foot shift, hand clutch
Primary Drive:
Multi-plate dry clutch, chain drive to transmission
Secondary Drive:
Belt drive to rear wheel
Gear Ratios:
Specific ratios would be detailed in the manual (e.g., 1st: ~2.44, 2nd: ~1.77, 3rd: ~1.34, 4th: 1.00)
Transmission Fluid Type:
Likely Harley-Davidson transmission lubricant or equivalent 75W-90 synthetic gear oil (check specific manual for OEM spec)
Audio System:
Optional factory or aftermarket AM/FM radio with CB/Intercom capabilities, typically integrated into the fairing.
Instrumentation:
Analog speedometer, tachometer (optional), oil pressure gauge, ammeter, fuel gauge, indicator lights for turn signals, high beam, oil pressure.
Assistance Systems:
None (Era-appropriate features only)
Connectivity Features:
None (Era-appropriate features only)
Oil Change Interval:
Typically every 2,000-3,000 miles or annually. Specific recommendations are in the manual.
Transmission Fluid Change:
Typically every 5,000-10,000 miles. Refer to manual for exact interval.
Primary Chain Tensioner Check:
Regular checks and adjustments are critical for primary drive longevity.
Engine Oil Type:
API SG or higher, SAE 20W-50 or 20W-40 motorcycle-specific oil (check manual for exact viscosity and API rating)
Engine Oil Capacity:
Approx. 4 US quarts (3.8 liters) with filter change
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid (check manual for specific recommendation and compatibility)
Shifter Pawl Wear:
Potential wear on the shifter pawl mechanism in the transmission, leading to difficulty shifting or false neutrals.
Primary Chain Tensioner:
The automatic tensioner design on early models could wear, requiring manual adjustment or replacement with later-style tensioners.
Carburetor Tuning:
Shovelhead carburetors often require periodic fine-tuning for optimal performance and fuel economy.
Oil Leaks:
Characteristic of Shovelhead engines; diligent maintenance of seals and gaskets is important.
