Diagnostic Level:
Covers basic operational checks, fluid level verification, wear inspection, and simple component replacement/adjustment.
Repair Complexity:
Focuses on owner-level maintenance and simple repairs, such as bulb changes, fluid checks, and basic adjustments. Does not detail engine rebuilds or complex electrical diagnostics.
Scope Of Documentation:
Comprehensive owner guidance covering operation, maintenance, and basic servicing. Includes essential technical data and troubleshooting for common issues.
Engine Type:
Two-stroke, single-cylinder (typical for 50cc scooters of this era).
Displacement:
Approximately 49cc (standard for a 50cc class scooter).
Cooling System:
Liquid-cooled (common for performance-oriented 50cc two-strokes to maintain consistent temperatures).
Horsepower:
Estimated 5-7 HP (typical for a de-restricted 50cc two-stroke scooter).
Torque:
N/A (Specific figures not provided in product info, but would be modest for its class).
Carburetor:
Likely a small-diameter carburetor (e.g., Dell'Orto PHVA 12 or similar).
Fuel Delivery:
Gravity feed from the fuel tank.
Oil Mixing:
Automatic oil injection system (as indicated by 'MIXER OIL TANK').
Dashboard Features:
Includes instruments and indicators, with a specific table listing their functions, covering speed, fuel level (likely), turn signals, high beam, and possibly oil level warning.
Lighting System:
Features automatic light switching (on some versions), headlight beam adjustment, and detailed procedures for changing various bulbs.
Wiring Diagram:
A comprehensive wiring diagram for the Rally 50 is provided, essential for electrical diagnostics and repairs.
Regular Service:
The manual includes a 'REGULAR SERVICE INTERVALS CHART' covering various maintenance tasks at specified mileage or time intervals.
Transmission Oil:
Specific Aprilia-branded or equivalent gear oil for scooters is recommended for transmission lubrication.
Brake Fluid:
DOT 4 brake fluid is typically recommended for Aprilia scooters of this era, as indicated by the 'BRAKE FLUID (recommendations)' section.
Fuel:
Unleaded gasoline, likely with a minimum octane rating of 95 RON (Super Unleaded).
2-Stroke Oil:
High-quality synthetic or semi-synthetic 2-stroke oil for automatic injection systems, as specified in the 'MIXER OIL TANK' section.
Common Wear Items:
As with many 50cc two-stroke scooters of this age, common wear items include drive belts, spark plugs, brake pads/shoes, and the battery. The manual provides guidance on checking and replacing these.
Carburetor Maintenance:
Carburetor cleaning and adjustment may be required periodically due to the nature of 2-stroke fuel/oil mixtures and potential for gumming.
Electrical Corrosion:
Older scooters can sometimes suffer from electrical connector corrosion; the manual's wiring diagram can aid in troubleshooting.
Lubricant Chart:
The manual contains a dedicated 'LUBRICANT CHART' detailing specific lubricant types and viscosities for various components.
Identification Data:
The manual includes a section for 'IDENTIFICATION DATA,' likely referring to VIN, engine number, and other crucial identifiers for accurate servicing.
