Electrical Diagnostics:
Procedures for testing ignition components, stator output, and troubleshooting electrical faults using a multimeter.
Depth:
Comprehensive, factory-level detail covering everything from basic maintenance checks to complete engine and drivetrain rebuilds.
Engine Type:
Two-stroke, piston-ported, fan-cooled
Engine Displacement:
Approximately 464cc (derived from Rotax 467 engine family).
Bore X Stroke:
Specifications typically available in manual (e.g., 76mm x 74mm).
Carburetion:
Single Mikuni VM Series carburetor (e.g., VM32 or VM34).
Horsepower Estimate:
Estimated 45-55 HP (varies by tuning and specific model year adjustments).
Fuel Type:
Leaded or Unleaded gasoline mixed with two-stroke oil (e.g., 20:1 or 25:1 ratio recommended by manufacturer).
Cooling Method:
Fan-cooled (forced air cooling).
Spark Plugs:
Check and clean/replace annually or as needed. Gap specification typically 0.025-0.030 inches.
Chaincase Oil:
Change annually or every 1000 miles. SAE 80W-90 hypoid gear oil is commonly used.
Clutch Inspection:
Inspect primary and secondary clutches annually for wear on buttons, rollers, and sheave faces. Check belt condition and tension.
Track Tension:
Adjust track tension seasonally and as needed. Typical sag is 1-1.5 inches.
Engine Oil:
API-TC certified two-stroke engine oil. Mixing ratio specified by manufacturer (e.g., 20:1, 25:1, or 40:1 depending on oil type and manufacturer recommendation).
Chaincase Oil Type:
SAE 80W-90 hypoid gear oil. Capacity typically around 200-250 ml.
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid (if equipped with hydraulic brakes).
Common Wear Items:
Clutch buttons/rollers, drive belts, ski carbides, track lugs, recoil starter cord, and carburetor diaphragms.
Engine Considerations:
Carbon buildup in exhaust ports and power valves (if applicable), potential for crank seal leaks over time, and carburetor jetting sensitivity to altitude/temperature.
Manufacturer:
Bombardier Recreational Products (BRP), a Canadian company renowned for snowmobiles, ATVs, and personal watercraft.
Everest Line:
The Everest line was a key offering for Ski-Doo, evolving through various engine sizes and chassis updates to meet diverse rider needs. The 500 E represented a mid-range option in the 1982 lineup.
Production Era:
1982 model year, part of Ski-Doo's extensive product range during the boom years of snowmobiling.
