Horsepower:
Estimated 30-40 HP (typical for this displacement and era). Exact spec not provided.
Torque:
Not specified in product information, but typical for a two-stroke of this size.
Carburetion:
Dual carburetors, likely Mikuni or Amal. Specific model number not provided.
Cooling Type:
Fan-cooled (air-cooled) is most probable for this model. Liquid cooling was less common on mid-range models in '75.
Oil Mixture:
Pre-mix gasoline/oil ratio (e.g., 40:1 or 50:1). Automatic oil injection was not universal on all models of this era.
Clutch System:
Automatic CVT (Continuously Variable Transmission) utilizing a primary (drive) clutch and secondary (driven) clutch.
Gearbox:
Not applicable; snowmobiles of this era typically used a single-speed CVT system.
Clutch Service:
Manual covers clutch inspection, adjustment, belt replacement, and spring/roller servicing.
Overall Length:
Not specified in product information, but typically around 80-90 inches for this class.
Dry Weight:
Not specified in product information, but likely in the range of 350-450 lbs.
Track Width And Length:
Not specified in product information, but typical track widths were 15 or 20 inches.
Display Features:
Basic dashboard with speedometer, engine temperature light (if equipped), and odometer. No advanced infotainment systems.
Assistance Systems:
N/A. Focus is on mechanical operation and rider input.
Connectivity Features:
N/A. No electronic connectivity features.
Engine Tune Up:
Recommended annually or every 100-150 operating hours, focusing on spark plugs, carburetor adjustments, and belt inspection.
Clutch Service:
Periodic cleaning and inspection of clutch sheaves, weights, and springs. Belt inspection for wear and damage every season.
Track Tension:
Check and adjust track tension before each riding season and periodically during use.
2 Stroke Oil:
API-TC rated, high-quality 2-stroke snowmobile oil. Specific brand recommendations would be in the manual, but generic API-TC is a safe bet.
Chaincase Oil:
Likely a light-weight gear oil or specialized chaincase oil. Specific viscosity (e.g., 0W-30 or 5W-30) would be detailed.
Common Wear Items:
Drive belts, clutch components (rollers, buttons, springs), track lugs, suspension bushings, and carburetor diaphragms/jets.
Ignition Reliability:
Older CDI units or stators can become a failure point; the manual provides testing procedures.
Carburetor Cleaning:
Essential for optimal performance, especially with fuel variations. Manual provides step-by-step cleaning and jetting guides.
