Did you know that Yamaha big bear 350 was introduced into the market by the Yamaha brand in 1987? Although it looks brilliant to date, it has a long-dated history.
As decades go by since its innovation, it won’t be a surprise if you experience problems with the Yamaha machine.
This article examines the common problems you may encounter while riding this Yamaha ATV.
So, Which Are Those Common Problems To Look Out For In Yamaha Big Bear 350?
Most Yamaha Big Bear Problems May Arise Due To Torque Issues
Your Yamaha four-wheeled machine will exhibit torque issues if it starts and slowly loses its torque. This issue may come up 5 to 10 minutes after starting the vehicle.
Signs Of Torque Problems Include The Following
The rider may lose torque after 5-10 minutes of starting up
The ATV acts to be flooding out
Solution
A torque problem occurs when the float gets cracked or sticks. It also could be due to a faulty spark plug.
To correct this problem, you need to replace the faulty part. For successful correction, we recommend looking for a qualified, certified mechanic.
If You Have Problems With Your Machine, It Could Be Carburetor Issues
The carburetor works by combining spray liquid fuel with air in a combustion engine. The carburetor may get dirty and faulty as you continuously ride your ATV.
The result will be a failing carburetor that brings problems to your rides.
Signs That The Problem Might Be The Carburetor
The carburetor often idles up
Frequent ATV cut-offs
Solution
The first step to repairing a faulty carburetor will be to soak it in carburetor cleaner for up to 48 hours. Let it dry out after the cleaning process.
If it proves problematic, you will need a Yamaha professional to check it out. Very damaged carburetors need replacing to guarantee excellent service.
It Could Be Throttle Issues
Have you had issues starting and running your big bear? Throttle issues will cause this machine to run terribly, and you might think the gas isn’t getting where it needs to be.
But on the contrary, this machine could run if allowed to warm up first. If you had left it under cold temperatures for a while, you could suffer the throttle issues.
Signs That You Are Experiencing Throttle Issues
The big bear has a rough start.
You might find the drive terrible if it finally starts.
Solution
You will need to conduct professional maintenance on your ATV. Let the regular maintenance involve cleaning the air filter.
Also, you might dissemble the carburetor and clean it often to prevent future throttle issues.
It might also do wonders if you may assemble new carburetor rebuilding and cleaning kits.
We recommend you look for a qualified Yamaha specialist to help you conduct regular cleaning maintenance. The Yamaha ATVs require unique skills to keep running longer.
Transmission Problem Signs With Your Yamaha Big Bear 350
Sometimes, the problem you experience with your machine could come from the transmission region.
Most UTVs come with a continuously variable transmission (CVT) system.
This system will allow the engine operation to work at optimum levels of power and efficiency.
The operation may vary depending on various conditions. The gear level will change per speed, load and rpm.
When the transmission system blows, your Yamaha UTV starts misbehaving and having trouble starting and running.
Signs That You Have Transmission Issues
Often, the big bear fails to start
Solution
You might have to let your Yamaha ATV get an inspection from a certified Yamaha specialist. If the problem proves challenging to resolve, you might get forced to replace it.
Note
UTVs come with a specified speed limit. Most Yamaha big bear 350 designs operate at 40 MPH.
You should not exceed this limit. Exceeding puts your UTV at risk of transmission blowing.
Is Your Big Bear Experiencing Problems? It Could Be The Carburetor
The carburetor combines fuel-to-air proportions in the correct proportions for combustion in the engine.
This combustion propels the machine forward, causing a successful movement. If your motor doesn’t start, it could mean that the carburetor has spoiled.
How Do You Tell If Your Yamaha Big Bear 350 Has Carburetor Issues?
The machines have a maximum idling time.
The machine cuts off and fails to start successfully.
Solution
Cleaning the carburetor might be the magical step to getting your ATV back on the terrain.
Once cleaned, the carburetor allows air and fuel to move and mix as intended to bring about combustion.
To clean the carburetor, soak it for 24-48 hours in carburetor cleaner. After the soaking, let it dry and assemble it back to the UTV.
If you still have issues with the carburetor, contact a Yamaha big bear 350 specialist for more help.
CDI Issues
UTVs prove to be very delicate machines. If you have CDI issues, it might be a problem for your big bear.
The CDI is a battery storing energy that, once released, helps achieve a successful ignition. If this part you find below the seat gets faulty, it may render your machine immobile.
Signs Of A Faulty CDI
The big bear might fail to ignite and start.
You hear a beeping sound when you measure it with a digital multimeter.
Solution
We recommend that you replace a faulty CDI for a better UTV experience.
Electrical Issues
Have you lost electric power with your Yamaha machine while on a ride? It happens often, and the lights flicker and go off, followed by a mega shutdown.
Often, when this happens, you go ahead and recharge your battery. Charging the battery and not solving the electrical issue results in a similar experience shortly after.
Signs Your Electric System Needs Attention
Flickering lights
Lights go off
The electric system shuts down
Solution
You will need a Yamaha electrical specialist to take a look at it. The battery connections, the rectifier, or the wiring might be causing the electrical problem.
Troubleshooting these areas could solve the problem.
If not, a proper diagnosis and replacement of major electrical components will have the big bear running in no time.
On And Off Start Struggles
Sometimes, your big bear may act out on you. If you start it and it slows down and finally shuts down, you need to understand the problem and how to solve it.
Have you given it some gas for it to start?
Or is it not idling as it should? All these problems might need you to try a few tricks to troubleshoot their problem.
It could be that the ATV has several problems limiting its potential. Remember always to conduct routine maintenance to keep all parts running smoothly.
Solution
Check the carburetor and clean it out.
Also, try changing the carburetor’s plug.
Check the choke mechanism and check for any blockages. If any, remove them for it to give a high idle.
Takeaway
To enjoy ATV riding experiences, you must learn about all possible problems.
We have provided you with this list of significant problems with your Yamaha big bear 350 and hope it gives you an upper hand.
We recommend that you perform DIY maintenance on simple problems. Remember to contact a Yamaha mechanical expert for challenging problems.
