Fuel Type:
Unleaded gasoline (typically 87 octane or higher).
Oil Mixture:
Premix (oil mixed with gasoline) or Autolube (oil injection system) depending on specific configuration. The ZR 500 typically used an oil injection system.
Oil Type:
2-stroke synthetic or semi-synthetic snowmobile oil (follow manufacturer recommendations for specific API/TCW rating).
Crash Test Results:
Snowmobiles of this era are not subject to traditional automotive crash testing standards. Safety focuses on operational design and user responsibility.
Braking System:
Hydraulic disc brake, providing reliable stopping power.
Throttle Control:
Thumb throttle with return spring for controlled acceleration.
Lighting:
Headlight, taillight, and brake light for visibility.
Kill Switch Lanyard:
Essential safety feature to shut off the engine if the rider is separated from the snowmobile.
Gauge Cluster:
Basic instrumentation including speedometer, tachometer, odometer, and indicator lights (e.g., oil, engine temp).
None:
Snowmobiles of this era are mechanically focused; advanced electronic driver assistance systems are not present.
None:
No electronic connectivity features like Bluetooth or GPS are standard on this model.
Initial Break In:
Specific break-in procedure (e.g., mileage or time) for new engines, crucial for longevity. Detailed in the manual.
Spark Plug Replacement:
Typically every 1,000-2,000 miles or annually, depending on usage and plug condition.
Drive Belt Inspection:
Inspect every 500 miles or annually for wear, fraying, or damage. Replace as needed.
Clutch Service:
Clutches should be inspected periodically for wear on buttons, rollers, and sheave surfaces. Specific intervals will be in the manual.
Track Tension Adjustment:
Check and adjust track tension regularly, especially after initial use or in varying snow conditions.
