5 Common Problems of CFMoto CForce 600 and Their Solutions:

Do you want to buy a CFMoto CForce 600 but wondering which problems you might have to confront while riding it? Or are you an owner who is struggling to find a reliable solution to your CFMoto CForce 600 Problems? Well, you’ve come to the right place.

CForce 600 has been in the market for so long, and since its arrival, it’s known for its high speed and power. Another reason why people are funding CForce 600 is its affordable price.

Despite all these things, although it is a fun vehicle, it still comes with many common flaws we have encountered while going through different forums. Let’s dig into them.

CFMoto CForce 600 Problems

These 5 common problems Shifting Gears Issues, Slow Throttle Response, Louder Engine Noise, Excessive Heat Exhaust, and Engine Not Starting that CForce 600 are facing, to help them out, I have discussed some of the best possible solutions.

1. Shifting Gears Issues

This is the first and most common problem the CForce 600 has, and it occurs when owners try to go into any gear from a complete stop on an incline.

Signs to know Shifting Gears is Troubling:

When you feel like your gears are stuck to some point, it becomes difficult to move them, or while shifting gears, if you’re hiring grinding noise or after shifting gears, it is throttling directly. This all indicates that there is something wrong with its shifting gears. 

Then happens when both or either one lock nuts loosen, which results in the shift’s transfer to the wrong position. 


  • To fix this, remove the plastic cover from the gear shift along with the plastic covering plate installed below the gear shift. For better results, you can remove the plastic cover from where “CFORCE” is spelled out. Now you can easily place back the shift linkage to its original position. While doing this, you need to ensure the transmission is neutral. 
  • If it is, take an 8mm wrench, hold the turnbuckle in place, and lose both locking nuts using a 10mm wrench. After loosening it completely, rotate the turnbuckle counter-clockwise to tighten the nuts and lock it back into place. 
  • Lastly, it’s time to check your vehicle to see whether it’s working. If not, you can try making a few more adjustments until your issue is resolved.

2. Slow Throttle Response

The next one is poor throttle response that occurs when you’re trying to run your ATV in 5th gear. While throttling the machine, the RPM shoots up and doesn’t get much response from the engine leaving the high gear useless, and then the owners are left with no choice other than to run it in low gear.

This causes your rides to be quaking at times because your vehicle is not getting enough power as it is supposed to be.  This problem is also the same in other CF models like CFMoto UForce 1000, and CFmoto CForce 400.


  • You can upgrade your primary clutch with new springs and weights to eliminate the causes. To do this, you’ll need an aftermarket clutch kit with upgraded components or purchase and install them on your own. 
  • You can also reclock the secondary clutch to a different setting so that you can get an increase in the throttle response. The setting is adjustable, having 3 different letters and 4 different number settings, so make sure to give it a factory setting and set it at B1. 
  • Now if you want a better experience, you can also set it at C1 for your convenience. 

3. Louder Engine Noise

We have also seen many owners complaining that their CFMoto CForce 600’s engine makes a thunderous noise during rides which becomes louder even after adjustments.

CForce 600 is designed with a big bore single cylinder engine and no wonder its sound is supposed to be louder because of its nature. But many owners don’t know that, and while trying to slow down the sound, they mess it up.


  • Valves play a vital role in making louder sounds; if you’ve loosened or tightened them more than required, they amplify the noise. So first, you need to ensure that all of its specs are set correctly, and if not, you have to adjust to their ideal specs to quieten your engine. 
  • You can also remove the plastic covering and use sound-deadening mats to help soften the engine noise. 
  • Clutch kit installation can also help you through this, as it will lower RPMs and cause high revving that cuts down on the noise.

4. Excessive Heat from Exhaust

Many riders have encountered this issue, especially those who run their ATVs at slower speeds in low gear. They have mentioned that the side where the exhaust pipe vents become hot from the heat, and that heat warms up the plastic fuel tank cover and outer plastic shell so much that there is no way out for the rider to ride on it without burning his leg.


  • Use the heat shield or heat wrap to cover the entire exhaust pipe as in this way, less heat will be warming the plastic shell and will make your rides more comfortable. 

5. Engine Not Starting

CForce 600’s owners have many times complained that their vehicle’s engine is not starting at all. This could be because of several reasons like Battery, Spark Plugs, Wiring, Valves, or Starter solenoids.


  • Battery-  CForce 600 is known for having a weak battery which gets drained a bit more quickly than others. So to check whether it is because of battery drainage or not, you’ve to test its battery voltage while giving it 12+ volts as to function properly, a battery needs at least 12 volts. Or you can also connect the battery to a tender.
  • Spark Plugs- Check out the spark plugs thoroughly and make sure there are no foreign substances such as oil, fuel, or coolant coated on it. This can also be determined by looking at its tip’s color, so you must ensure it looks like and is not burnt.

If it is, then it would be because of fouling, so it’s high time to replace them with top-quality iridium spark plugs. 

  • Wiring- There is a high chance that the reason could be battery wiring/terminals, so you need to inspect the wires and make sure that the grounding wires are still connected to the battery a that there is no debris and corrosion stuck to the battery terminals. Clean the terminals thoroughly, even if you feel like it’s not needed, before applying dielectric grease or petroleum jelly on top of them to prolong theirs. 
  • Starter Solenoid- While trying to start your vehicle, if you’re only hearing the clicking sound, but the engine is not getting fired up, then this could be because of starter solenoid issues. So here, the first thing you need to do is check all of the connections on the solenoid and make sure they aren’t loose at all.

Then the next thing you have to do is try adjusting the solenoid even if you think it isn’t needed, as it is one of the most highly effective tricks. Now if it still doesn’t work, then you should test the solenoid using the screwdriver and laying it across the two large lugs and then try to start it up. At this time, if your engine is firing, then it indicates that you need to replace the solenoid.

  • Valves- Valves could also be the cause of your vehicle’s engine starting issues because of their intake or exhaust properties. There is a higher chance that it is happening because the valves are making compression loss, but it could also be because of loosening.

So, in short, either tightening or loosening can cause this issue, so you need to maintain the valves at the proper level (written in the owner’s manual) as if not, that can result in loss of compression.

Final Verdicts:

CFMoto CForce 600 has been a player in the ATV industry for a longer time, and as it’s been a long time, there will be a lot of buyers too. Just like other ATV vehicle owners, its owners have several different problems too. 

Some of the most common problems which its owners are facing are mentioned above that will help you in either case whether you’re thinking of buying this one or have already bought it.
