(1200cc) Big Twin engines, though smaller displacements might have been offered in earlier or specific configurations. Manual will cover applicable variants. Bore X Stroke: For 74 cu. in. (WL/WLA based engines): 3.375 in. x 4.25 in. Compression Ratio: Varies by year and specific model, typically around 5.0:1 to 7.0:1 for this era. Performance Horsepower: Estimated 20-30 HP (at the crankshaft) depending on exact engine variant and tuning. Torque: Significant low-end torque, characteristic of Harley-Davidson Big Twins. Fuel System Carburetion: Single carburetor, typically a Linkert M series (e.g., M74, M88) or similar for the period. Manual will detail specific models. Fuel Type: Leaded gasoline (specific octane ratings will be detailed in manual). Lubrication System: Total loss oil system (oil is consumed/burned, requiring constant replenishment and management). Oil Type: Specific Harley-Davidson recommended oils for the era (e.g., SAE 50 motorcycle oil, potentially with specific additive packages). Manual will specify. 🔧 Transmission Standard Type: 3-speed, constant mesh, foot-shift (left foot clutch, right foot shift lever) and hand clutch lever on some models, evolving to foot clutch and hand shift on others within this range. Optional Options: Not typically offered with transmission options for this utility model. Features Drive: Chain drive to rear wheel and drive shaft to the third wheel/differential assembly. Fluid Type: Specific Harley-Davidson transmission lubricant for the period (likely a heavier weight gear oil). Manual will specify. 📐 Dimensions Exterior Wheelbase: Approximately 64.5 inches (dependent on specific Servicar configuration). Length: Varies by body configuration, but significantly longer than a standard motorcycle due to the sidecar/cargo unit. Weights Dry Weight: Estimated 600-700 lbs, depending on configuration (single driver, dual driver, cargo box, etc.). Gross Vehicle Weight Rating: Not explicitly defined as a modern GVWR, but capacity for rider, passenger, and cargo is critical. 🛡️ Safety Features Ratings Crash Tests: N/A - Vehicles of this era were not subject to modern crash testing standards.
