The Yamaha Wolverine 850 has been known to deliver an exceptional off-road experience to riders.
However, as with any mechanical device, it may occasionally encounter certain problems.
In this article, I will highlight some of the common issues Yamaha Wolverine 850 owners reported and provide solutions.
Yamaha Wolverine 850 Problems
1. Inadequate Heating
The heating problem seems to plague the Wolverine 850 models exclusively. Users have reported that the heating system doesn’t produce as much heat as expected.
The issue could be attributed to the default thermostat settings, which start opening at 154°F and are fully operational at 180°F.
However, when the vehicle is in motion, the thermostat doesn’t rise above 170°F, inhibiting the heater’s functionality.
Solution: Some users have suggested blocking off the radiator and insulating the pipes to increase heat generation.
However, this solution might only be effective in moderately cold conditions.
Yamaha is reportedly aware of the issue and is working on a permanent fix.
2. Rider Discomfort
One significant issue riders face is discomfort due to foot positioning while navigating challenging terrains at low speeds.
However, the foot angle is comfortable at 30 mph; it can become painful at 2-3 mph.
Solution: You can use a wooden block in front of the gas pedal because it can elevate the foot’s heel to a comfortable angle at any speed.
However, this is a workaround and not a permanent solution.
3. Throttle Responsiveness
Some Wolverine 850 models have reported unresponsive throttles or harsh acceleration.
Although dealers often say this is due to poor fuel quality, a slack throttle cable, or a faulty seat/seatbelt sensor, it is usually due to fuel insufficiency.
Solution: Monitor how long it takes for the machine to show issues, and check if your fuel line or pickup is defective.
You also need to inspect the choke butterfly, clean the carb and air filter, and drain the tank completely.
4. Fuel Tank Issues
Water leakage into the fuel tank can occur due to rainwater infiltration or a loose tank top.
This can be especially detrimental to motorcycles equipped with YFI, as water can damage engine components and fuel injectors.
Solution: If you notice starting problem during acceleration.
You should immediately remove the water from your tank by siphoning it from the gas cap or draining it via the drain plug.
5. Cab Heat Intensity
A frequently discussed issue with the Yamaha Wolverine 850 is the intensity of the cab heat.
This is primarily due to cooling lines running along the firewall, causing the driver’s right foot and the passenger’s left foot to heat up.
Solution: Opening the door and insulating the tunnel alleviates this issue.
6. Parking Brake Issues
The Wolverine’s engine braking system (EBS) is exceptional, but the parking brake can occasionally get stuck.
Solution: Never leave your brake on overnight to prevent this issue.
If it does occur, you can disengage the brakes by rocking your vehicle back and forth or manually pulling the brake wires.
7. Engine Problems
Engine problems can range from reduced engine power to overheating and starting issues.
It is mostly due to a blocked injector, empty fuel tank, dirty or broken spark plug, damaged ignition coil, or a blown crankshaft position sensor.
Solution: Replacing the faulty part can resolve Most of these issues.
