Yamaha PZ50RTH, PZ50XTH, PZ50MTH 2017 Venture Multi Purpose Owner's Manual

The recommended maintenance intervals are every 500 miles or every season, whichever comes first. This includes checking the oil, spark plugs, brake system, and drive belt.
To store your snowmobile, first clean it thoroughly and ensure it is dry. Add fuel stabilizer to a full fuel tank, change the oil, and lubricate all components. Remove the battery and store it in a cool, dry place. Cover the snowmobile with a breathable cover.
First, check the battery to ensure it is charged. Verify that the fuel tank has fresh fuel and that the fuel lines are not blocked. Inspect the spark plugs for wear or damage and replace them if necessary. Also, check the kill switch and ensure it is in the correct position.
Overheating can be caused by a lack of coolant, so check the coolant level and top it off if necessary. Inspect the cooling fins for debris and clean them. Ensure that the thermostat is functioning properly and the water pump is working efficiently.
Yamaha recommends using Yamalube 4-stroke oil, specifically formulated for their snowmobiles. Using the correct oil ensures optimal performance and longevity of the engine.
To adjust the track tension, lift the rear of the snowmobile and support it securely. Loosen the axle bolts and adjust the tension bolts until the track has about 1 inch of slack when lifted at the midpoint. Tighten the axle bolts once the correct tension is achieved.
Before each ride, check the oil level, coolant level, and fuel level. Inspect the brakes, throttle, and steering for proper operation. Verify that the skis and track are in good condition, and ensure all lights and signals are functioning.
To clean the carburetor, remove it from the engine and disassemble it. Use a carburetor cleaner to spray all jets, passages, and components. Carefully reassemble the carburetor, ensuring all parts are dry and free of debris before installation.
While aftermarket parts can be used, it is recommended to use genuine Yamaha parts for replacement and repairs. Genuine parts ensure compatibility and maintain the integrity of the snowmobile's performance and warranty.
Common signs include unusual vibrations, a burning rubber smell, or visible wear and tear on the belt. If the belt is frayed, cracked, or glazed, it should be replaced immediately to prevent further damage to the snowmobile.
