The recommended oil type for Yamaha FX Nytro models is Yamalube 4W 10W-40 or an equivalent 4-stroke engine oil that meets the API service classification of SJ or higher.
To adjust the track tension, lift the rear of the snowmobile and ensure the track hangs freely. Measure the deflection at the midpoint of the track by applying a 10-pound weight. Adjust the tension bolts located at the rear axle until the track deflection is within the specified range in the owner’s manual.
The correct spark plug gap for the Yamaha FX Nytro 2014 models is 0.024–0.028 inches (0.6–0.7 mm).
The drive belt should be inspected regularly for wear and replaced if there are signs of cracking, fraying, or significant wear. Yamaha recommends checking the belt condition every 1,000 miles and replacing it as needed.
If your Yamaha FX Nytro won't start, check the following: ensure the kill switch is in the 'run' position, verify the fuel tank has gas, check the battery connections, inspect the spark plugs, and examine the fuses. If the problem persists, consult a professional technician.
To improve fuel efficiency, maintain proper track tension, ensure the engine is well-tuned, keep the ski alignment correct, and avoid aggressive acceleration. Regular maintenance and using the recommended oil can also help in achieving better fuel efficiency.
For off-season storage, clean the snowmobile thoroughly, change the oil and filter, lubricate all moving parts, stabilize the fuel, remove the battery and store it in a cool, dry place, and cover the snowmobile to protect it from dust and moisture.
Adjust the suspension settings by first setting the preload on the front and rear shocks to match your weight and riding style. Then, adjust the compression and rebound settings according to the terrain. Refer to the owner’s manual for specific adjustment procedures and recommended settings.
Overheating can be caused by clogged radiators, low coolant levels, or a malfunctioning thermostat. To prevent overheating, ensure the cooling system is clean and full, check for leaks, and regularly inspect the thermostats and radiator caps. Regular maintenance is key to preventing overheating issues.
To replace the headlight bulb, first remove the hood of the snowmobile. Disconnect the electrical connector from the back of the headlight assembly, remove the rubber boot, and release the spring clip holding the bulb. Insert the new bulb, secure the spring clip, replace the rubber boot, and reconnect the electrical connector.
