Polaris 600 800 Switchback Assault User's Guide

To break in your Polaris 600/800 engine, start by running the machine at varying RPMs for the first few hours, avoiding prolonged full-throttle operation. This process helps seat the piston rings and ensures optimal performance.
Perform the first oil change after the initial 500 miles. Regularly check and replace the oil every 1,000 miles or annually. Inspect the drive belt, suspension components, and brake system every 500 miles or as needed.
If the engine is not starting, check the battery connections and charge level. Ensure the kill switch is in the 'run' position and inspect the spark plugs for fouling or damage.
Ensure the coolant level is sufficient and inspect the radiator for obstructions. Check the thermostat and water pump for functionality. Cleaning the heat exchangers and ensuring proper airflow can also help prevent overheating.
Adjust the preload on the front and rear shocks to match your riding style and weight. For firmer handling, increase the preload. Refer to the owner's manual for specific settings based on terrain and rider preference.
Use 91 octane or higher gasoline without ethanol for optimal performance. Avoid using fuel with more than 10% ethanol as it can cause performance issues and engine damage.
Consider installing studs on the track for enhanced grip on icy or hard-packed snow. Adjusting the track tension and ensuring it is properly aligned can also help improve traction.
Power loss can be caused by clogged air filters, fuel delivery issues, or worn spark plugs. Regularly clean or replace the air filter, inspect fuel lines for blockages, and check the spark plugs for signs of wear or fouling.
Identify the source of the noise. Loose components, worn bearings, or drive belt issues can cause unusual sounds. Tighten loose parts, replace worn bearings, and inspect the drive belt for damage.
Consider upgrading the exhaust system, clutch kit, or installing performance reeds. Regular maintenance, including cleaning the carbs and ensuring optimal engine tuning, can also enhance performance.
