Engine Type:
Evolution (Evo) V-twin, air-cooled, pushrod overhead valve (OHV)
Engine Displacement Variants:
Common displacements include 883cc (53.9 cu in) and 1100cc/1200cc (67.5 cu in/73.2 cu in) across the covered years. Specific variants depend on model year and trim (e.g., Sportster 883 Hugger, Sportster 1200 Custom).
Horsepower Torque:
Varies by displacement and year, typically ranging from approximately 50-65 HP for 883cc models and 60-75 HP for 1200cc models. Torque figures are also displacement-dependent.
Carburetion:
Primarily Keihin CV (Constant Velocity) carburetors (e.g., CV 34mm for 883, CV 40mm for 1200). Some earlier models may have used different carburetor types, and later models within this range might see fuel injection.
Fuel Type:
Unleaded gasoline, typically requiring 91 octane or higher depending on compression ratio.
Transmission Type:
5-speed constant mesh manual transmission
Optional Transmissions:
None standard; all models in this range are 5-speed manual.
Clutch Type:
Wet, multi-plate clutch, operated by cable.
Final Drive:
Primary drive: Chain. Final drive: Belt (most common across the range, though some early models might have used chain final drive).
Safety Standards:
As a motorcycle, formal crash ratings are not typically applied. Focus is on rider protection through design and components.
Braking System Type:
Hydraulic disc brakes front and rear. Early models might have single front disc, later models often dual front disc for 1200cc variants. Rear is typically single disc.
Lighting:
Halogen headlight, taillight, brake light, front and rear turn signals.
Infotainment System:
This era of Sportster generally did not feature sophisticated infotainment systems. Basic features include analog speedometer, tachometer (on some models), odometer, and warning lights.
Driver Assistance Features:
None standard. Focus is on mechanical controls and rider feedback.
Connectivity Options:
None. Communication is purely mechanical and electrical.
Oil Change Interval:
Typically every 2,500-5,000 miles (4,000-8,000 km) or annually, whichever comes first. Refer to specific manual for exact mileage and oil type.
Primary Drive Oil Change:
Recommended at similar intervals to engine oil changes, or as specified in the manual.
Engine Oil:
Harley-Davidson Genuine V-Twin Synthetic 20W-50 or equivalent high-quality motorcycle-specific 20W-50. Specific API service classification might be noted.
Primary Chain Case Oil:
Harley-Davidson Primary Chaincase Lubricant or equivalent. Capacity typically around 1 quart (0.95 L).
Transmission Oil:
Harley-Davidson Transmission Lubricant or equivalent SAE 80W-90 gear oil. Capacity typically around 1 quart (0.95 L).
Brake Fluid:
DOT 4 hydraulic brake fluid (for models equipped with hydraulic brakes).
Carburetor Performance:
Keihin CV carburetors can sometimes experience diaphragm issues or require jetting adjustments for altitude or modifications.
Ignition Module Failures:
Older electronic ignition modules can be a point of failure, leading to no-spark conditions.
Regulator Rectifier:
Common wear item in many Harley models of this era; failure leads to charging system issues.
Cam Chain Tensioners:
Early Evolution engines had spring-loaded cam chain tensioners that could wear; hydraulic tensioners were introduced later, but checking for wear is advisable.
Belt Drive Wear:
The belt drive can wear over time and require replacement; proper alignment and tension are crucial.
Oil Filter Example:
Common Harley-Davidson oil filter part numbers for this era include 63796-77A, 63805-80, and later variations. The manual will provide specific part numbers for each year/model.
Harley Davidson Legacy:
The Sportster line is one of Harley-Davidson's longest-running and most iconic models, originating in 1957. It represents a more agile and sporting alternative to the larger V-twin touring bikes.
Sportster Xl Evolution:
The 1986 model year marked a significant evolution with the introduction of the rubber-mounted Evolution engine, addressing vibration issues and improving rider comfort. This manual covers the primary years of this modernized Sportster platform.
Manufacturing Location:
York, Pennsylvania, USA (Harley-Davidson's primary manufacturing facility).
