Vehicle Information
Ski-Doo Cheyenne 503 Snowmobile (1987-1991)
The Ski-Doo Cheyenne 503, produced from 1987 to 1991, was a popular snowmobile model often positioned within the broader Safari line. It consistently featured a reliable 496cc/497cc fan-cooled twin-cylinder Rotax engine. This engine, similar to the Rotax 503 aircraft engine, provided approximately 37 kW (50 hp) at 6800 rpm, ensuring robust performance for its class. The sources indicate no significant mid-cycle generation changes or major engine overhauls for the Cheyenne 503 during this period. The 'R' designation, as seen in 'Safari Cheyenne R', likely denoted a specific trim level or package rather than a fundamental generational shift. The core engine and platform remained consistent from 1987 to 1991. FAQ:

Maintenance
| Component | Interval | Details |
| Injection Oil Reservoir | Before every ride | Check and refill with manufacturer-specified injection oil. Insufficient oil can severely damage the engine. |
| Drive Belt | Inspect before every ride; replace if worn or every season | Visually check for wear (cracks, fraying, flat spots). Replace if signs of wear are present or every 2 400 to 4 800 km. |
| Spark Plug | Every 50 hours or annually | Inspect or replace every 50 hours of operation. Replace annually to prevent issues. Common types are BR9ES or BR9EIX. |
| Air Filter | Annually or pre-season | Inspect the airbox and air filter. Clean or replace as needed based on condition. |
| Coolant | Check before every ride; change every 2 years | Check level when cold before every ride. Change coolant every two years, regardless of use. Use a 50/50 premix specified for powersports. |
