Regular maintenance should include checking the oil level every 10 hours of operation, changing the oil and filter every 50 hours, inspecting the air filter every 25 hours, and replacing it as needed. Additionally, inspect and clean the spark arrestor every 100 hours and check the drive belt every 50 hours.
If the RZR XP 900 won't start, check the battery connections for tightness and corrosion, ensure the battery is fully charged, and inspect the fuses. Additionally, check the spark plug for fouling and ensure that fuel is reaching the engine.
Polaris recommends using their PS-4 Extreme Duty 10W-50 synthetic oil for optimal performance in the RZR XP 900, especially under extreme conditions.
To enhance suspension performance, consider upgrading to aftermarket shock absorbers, adjust the preload settings to suit your riding style, and regularly check and maintain the suspension components for wear and tear.
First, ensure that the radiator is clean and free of obstructions. Check the coolant level and top off if necessary. Inspect the fan and thermostat for proper operation, and ensure there are no leaks in the coolant system.
To replace the drive belt, remove the clutch cover, take note of the belt's orientation, and slide the old belt off the clutches. Install the new belt by following the reverse procedure, ensuring the belt is properly seated before replacing the cover.
Common electrical issues include blown fuses, corroded connectors, and faulty switches. Regularly inspect the wiring harness for damage, clean and tighten all connections, and replace any faulty components as needed.
Regularly inspect the brake pads for wear and replace them when necessary. Check the brake fluid level and top off with the recommended DOT 4 fluid. Bleed the brake system to remove air and ensure optimal braking performance.
The recommended tire pressure for the RZR XP 900 is typically 12 PSI for all tires. However, consult your owner’s manual for the exact specifications as they may vary based on the terrain and load.
To improve off-road performance, consider installing larger tires with a more aggressive tread, upgrading the suspension system, and tuning the engine for increased power output. Also, ensure that all maintenance is up-to-date to prevent mechanical failures.
