Varies, but typically longer than a standard motorcycle to accommodate the cargo bed.
Length:
Varies by specific Servicar configuration and cargo bed size.
Dry Weight:
Typically in the range of 600-700 lbs (270-320 kg) depending on configuration.
Gross Vehicle Weight Rating:
Significantly higher than a standard motorcycle, rated for commercial payload.
Cargo Bed Dimensions:
Variable based on specific Servicar body style (e.g., open bed, enclosed box).
Payload Capacity:
Designed to carry substantial loads, often hundreds of pounds.
Safety Standards:
Reflects era-specific safety considerations for motorcycles and utility vehicles. No modern crash test ratings apply.
Braking System:
Drum brakes on front and rear wheels, potentially a mechanical parking brake.
Lighting:
Headlight, taillight, brake light, and possibly turn signals depending on local regulations and factory options.
Engine Oil Change:
Every 1,000 - 2,000 miles or annually, whichever comes first (typical for the era).
Transmission Oil Change:
Annually or as per manual recommendations, typically alongside engine oil service.
Spark Plug Service:
Inspect and clean/gap every 2,000-3,000 miles, replace as needed.

Check and adjust chain tension every 500-1,000 miles.
Primary Chaincase Oil:
Specific Harley-Davidson primary lubricant or equivalent (e.g., SAE 50).
Brake Fluid:
N/A (Mechanical drum brakes, no hydraulic fluid unless later modified).
Carburetor Tuning:
Linkert carburetors can be finicky and require precise adjustment for optimal performance. Susceptible to wear.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical faults. Generator charging systems may require regular maintenance.
Gasket Leaks:
