Diagram Clarity:
Exploded diagrams are typically clear, illustrating the order of assembly and individual components.
Engine Type:
2-stroke, single-cylinder
Displacement:
Approx. 125cc (specific bore and stroke not detailed in product info but inferable for the 125 class)
Cooling System:
Air-cooled
Ignition System:
Magneto ignition (typical for this era)
Kickstart:
Standard kickstart mechanism
Horsepower Estimate:
Estimated 20-25 HP (typical for performance 125cc off-road bikes of the era)
Fuel Delivery:
Carburetor
Fuel Type:
Pre-mix gasoline (typical for 2-stroke engines)
Engine Rebuild Interval:
Highly variable based on usage; top-end rebuilds (piston, rings) every 50-100 hours of use, full engine rebuilds less frequent but dependent on conditions.
Air Filter Cleaning:
Frequent cleaning and re-oiling, often after every few rides in dusty conditions.
Chain Lubrication:
Regularly, ideally after every ride, especially in wet or muddy conditions.
Transmission Oil:
Typically SAE 80 or SAE 90 gear oil (specific viscosity should be confirmed by actual manual or historical data).
Fork Oil:
Specific viscosity and quantity would be detailed in a service manual, not typically in a parts catalog. Common values were around SAE 5W or 10W.
2 Stroke Oil Mix:
Specific ratio and type of 2-stroke oil recommended by Husqvarna for their engines (e.g., Motul, Castrol, or Husqvarna branded oil).
Common Wear Items:
Piston and rings, clutch plates, wheel bearings, swingarm bearings, fork seals, ignition points (if applicable).
Carburetor Tuning:
Can be sensitive to altitude, temperature, and jetting, requiring periodic adjustment.
Clutch Slippage:
Common with hard use; may require adjustment or replacement of plates/springs.
