Engine Type:
Air-cooled, Evolution (Evo) V-twin
Displacement:
1340 cc (82 cubic inches)
Bore X Stroke:
3.50 in x 4.25 in (88.9 mm x 108.0 mm)
Compression Ratio:
8.5:1 (typical for this era)
Cylinder Configuration:
45-degree V-twin
Valve Train:
Overhead valves (OHV), pushrod actuated
Horsepower:
Approximately 65-70 hp (Estimate, factory figures often not explicitly published for this period)
Torque:
Approximately 75-80 ft-lbs (Estimate, factory figures often not explicitly published for this period)
Fuel Delivery:
Keihin CV (Constant Velocity) Carburetor, 40mm
Fuel Type:
Unleaded gasoline, 87 octane minimum (check manual for specific recommendations)
Oil Type:
Harley-Davidson SYN3 (synthetic) or compatible V-Twin specific motorcycle oil (e.g., 20W-50)
Oil Capacity:
3.0 US quarts (2.8 liters) (Check manual for exact capacity with filter change)
Oil Filter Part Number:
e.g., Harley-Davidson 63796-77, 63805-80, 63731-57T (Verify with manual for specific fitment)
Initial Service:
First service typically at 1,000 miles (1,600 km) or 6 months, whichever comes first.
Routine Maintenance:
Engine oil and filter change every 5,000 miles (8,000 km) or 12 months. Primary chaincase oil change every 10,000 miles (16,000 km) or 24 months. Check and adjust drive belt tension every 5,000 miles (8,000 km). Inspect and lubricate steering head bearings annually.
Engine Oil Viscosity:
20W-50 recommended for most conditions (check manual for specific temperature ranges).
Brake Fluid Type:
DOT 4 hydraulic brake fluid (ensure cleanliness during replacement).
Fork Oil Type:
Harley-Davidson Type 'E' or equivalent 10W fork oil (check manual for specific weight and capacity).
Primary Chain Tensioner:
Early models (pre-2001) used an automatic hydraulic tensioner that could wear out, leading to noise and potential primary chain damage. Manual replacement with an upgraded component is often recommended.
Carburetor Idle Issues:
The CV carburetor can sometimes develop idle stability problems due to worn internal components or improper adjustment.
Rear Brake Drum Wear:
In some cases, the rear brake drum could experience premature wear, requiring replacement.
Electrical Connector Corrosion:
Like many motorcycles of this era, electrical connectors can be susceptible to corrosion over time, leading to intermittent electrical issues.
Brand Establishment:
Harley-Davidson Motor Company, founded in 1903, renowned for its iconic V-twin motorcycles and cruiser culture.
Dyna Lineage:
The Dyna platform, introduced in 1991, offered a blend of classic styling with modern performance. The Wide Glide variant distinguished itself with its raked-out front end, ape hanger handlebars, and distinctive styling cues.
Engine Development:
The 1340cc Evolution engine, introduced in 1984 for the Softail models, was adapted for the Dyna line, providing robust torque and character. This engine became a staple for Harley-Davidson for many years.
Production Period:
1991-1998 for the FXDWG Dyna Wide Glide with the 1340cc Evolution engine.
