1450cc (88 cubic inches)
Bore X Stroke:
3.75 in x 4.00 in (95.25 mm x 101.6 mm)
Compression Ratio:
8.8:1 (typical)
Valvetrain:
Overhead valves (OHV), 2 valves per cylinder, pushrod actuated.
Horsepower Est:
~60-65 HP @ 5000 RPM (approximate, varies by tuning)
Torque Est:
~75-80 lb-ft @ 3000 RPM (approximate, varies by tuning)
Carburetion:
Keihin CV (Constant Velocity) 40mm carburetor (standard for most models in this range).
Fuel Type:
Unleaded gasoline, 87 octane or higher.
Oil Change:
Every 2,500-5,000 miles or annually, depending on usage and oil type.
Primary Chain Tension:
Check at 1,000 miles and then every 5,000 miles.
Spark Plugs:
Replace every 10,000-20,000 miles (depending on plug type).
Belt Drive Inspection:
Inspect for wear and tension at regular intervals (e.g., 5,000 miles).
Engine Oil:
Harley-Davidson 20W50 motorcycle oil (or equivalent API CI-4/SJ or higher).
Primary Chain Case Oil:
Harley-Davidson primary chain case lubricant, or SAE 75W/90 gear oil (API GL-4).
Transmission Oil:
Harley-Davidson transmission fluid, or SAE 75W/90 gear oil (API GL-5).
Brake Fluid:

Fork Oil:
Specific weight oil (e.g., 10W or 15W) as per manual, capacity varies by fork type.
Cam Chain Tensioners:
Early Twin Cam engines (pre-2007) were known to have issues with cam chain tensioners wearing out, potentially leading to engine damage. This manual would detail inspection and replacement procedures.
Rear Cylinder Overheating:
Air-cooled V-twins can experience increased heat in the rear cylinder, especially in hot weather or stop-and-go traffic. Proper lean mixture and maintenance are crucial.
Carburetor Tuning:
CV carburetors can require periodic adjustment for optimal performance and fuel economy.
Electrical Connections:
Vibrations can sometimes lead to loose electrical connections or corrosion, requiring inspection and tightening.
Heritage:
Harley-Davidson has a long-standing reputation for building iconic American motorcycles with a focus on rider experience and a distinctive sound and style.
Dyna Platform Introduction:
The Dyna platform was introduced in 1991, evolving from earlier Big Twin models with a focus on improved handling and a more modern riding experience. The Wide Glide variant is characterized by its raked-out front end and extended forks, reminiscent of classic chopper styling.
Fxwdg Specifics:
The FXDWG Dyna Wide Glide combines the classic 'chopper' aesthetic with the Dyna chassis. Throughout the covered years (1999-2005), the model received evolutionary updates, particularly in the engine and braking systems, and refinements to suspension and electrical components.
Manufacturing Location:
United States
