One of CFMoto’s UTVs is the UForce 600, which is a really good piece of equipment and definitely a high value for money. If you are in the market for a new or used UForce 600, you are also curious about what problems can occur with this ATV.

We have highlighted 6 of these problems and also tell you how to fix them and what the costs are. Even though 6 issues are discussed, it doesn’t mean it’s a bad vehicle, every ATV from every supplier has issues, so does the UForce 600.

1. Malfunctioning Speedometer

A typical issue reported by UForce 600 owners is a defective speedometer. It may break down due to bad wiring, a faulty speed sensor, or a damaged gauge. A malfunctioning speedometer gives inaccurate speed readings, which might be hazardous.

Start by examining the wiring and speed sensor if this problem persists. Make that the speed sensor is not broken, the wiring is not disconnected, and both are in good condition. If they are damaged, you may need to replace the wiring or speed sensor. Further, replace the gauge cluster if the gauge is defective. Recalibrate the speedometer following any component replacement to ensure accurate readings.

2. Hard Shift

Difficulty shifting gears can be a bothersome problem because it can make driving the vehicle smoothly challenging. Several different factors can lead to this issue, but fortunately, there are also several solutions you can attempt:

  • A clutch issue is one potential reason for the difficulty of gear-shifting. It may be difficult to correctly engage or disengage the gears if the clutch is worn out or damaged. It would be best to have the clutch fixed by a qualified mechanic or replace it completely to resolve this problem. You can get CFMoto UForce 600 for $149.99
  • Low transmission fluid is another potential reason why gears are difficult to shift. Gear grinding or slipping may occur if the fluid levels are too low. Make sure to check the fluid levels and top off as necessary regularly. Consider changing the oil if it has been a while since it has been changed. CFMoto Oil Change Kit is around $61.95.
  • Shifting gears can also be problematic if the gear selector is broken. The selector might not properly engage the gears if worn out or damaged. You should hire a qualified mechanic to replace the selector. The gear shifter kit can cost $161.18.
  • Changing gears at higher RPMs. It is more difficult to shift gears when the RPMs are high. To smoothly change into a different gear, you must find the sweet spot where the load on the gears is the least. It’s the main reason why the problem arises more often when on an incline. You can tap the brake and the gas pedal simultaneously when shifting gears; it makes the shift less difficult. In addition, adjusting the shift linkage should help.
  • Misaligned shift linkage. The shift linkage frequently moves to the wrong position because the lock nuts that keep it in place vibrate loose over time. It must be set back into the proper position to resolve the issue. You can correct it by finding and readjusting the shift linkage cable under the passenger seat toward the middle of the UTV. Two locking nuts help to secure it. To go to the right, loosen the back nut by 1.5 to 2 turns. Then, to secure it in place, tighten the front nut in the same direction. You can use the gear shift as you adjust to ensure the shift linkage resets in the proper position.

3. Engine Noise

Despite having a single cylinder, the UForce 600’s engine makes much more noise than the UForce 800 and UForce 1000s V-Twin engines, which are more potent. This engine noise, which is increased in vehicles with a full cab enclosure, can be so loud that it’s occasionally difficult to hear your passenger while driving.

Many owners have gotten around this by installing soundproofing mats in their rigs. Sound insulation in places like the motor cover, the motor tunnel, the exhaust manifold beneath the motor, and the storage boxes under the seats can help to reduce noise.

Many things, such as low oil levels, dirty oil, loose valve tappets, worn-out piston rings, and faulty timing chains, may also cause excessive engine noise. Abnormal engine noise might cause expensive repairs if it is not addressed.

Check the condition and level of the engine oil first before trying to resolve this problem. If the oil condition and level are ok, you may need to replace the worn-out piston rings or damaged timing chains. A UForce 600 piston ring set costs around $60, and a timing chain about $50. In some cases, tightening loose valve tappets can also help reduce engine noise.

4. Insufficient Accelerator Pedal Response

A jerky ride arises from a poor gas pedal response at lower speeds. Although the jerkiness largely goes away once the vehicle exceeds a speed of 15 to 20 mph, the problem can make trail riding or stop-and-go riding challenging.

A flaw in the original clutch system primarily causes this problem. It also affects several CFMoto ATV models and the UForce 1000.

You can eliminate this jerkiness at low speeds in one of two ways:

Adjusting the electronic control unit (ECU)

Calibrating the ECU for each throttle position and RPM range helps recalculate your vehicle’s ideal air-to-fuel ratios. It leads to a significantly improved throttle response, which aids in reducing the jerkiness felt at low speeds.

Also, modifying the ECU has additional advantages, such as boosting horsepower and torque. Moreover, it can typically be programmed to cause the radiator fan to turn on at a lower engine temperature, which helps prevent overheating.

Upgrading the Clutch

There are two ways to upgrade the clutch, both of which should resolve the jerkiness issue:

  • A Primary Clutch Kit
    You can install a clutch kit for their primary clutch, which typically improves the stock clutch system’s spring and weights. Different aftermarket clutch kits can assist in resolving the UForce 600’s clutch problems and lead to a comfortable ride at slower speeds. Clutch kits are available for $149.95 – 485.94
  • Re-Clocking the Secondary
    An adjustable spring in the secondary clutch may re-clock to a different setting if you want to save some money and handle this task yourself. Twelve different settings are available this spring, each with a unique combination of power, acceleration, and speed. The B-1 setting is the default setting for the UForce 600. You can reduce the jerky ride by re-clocking the spring to the A-1 or C-1 settings.

5. Coming to Halt while Turning

Many UForce 600 Owners frequently complain that their UTVs come to a stop while turning. This can be quite risky, particularly if it occurs while traveling at a greater speed. A malfunctioning fuel pump is the most probable source of this issue.

The engine may stall while turning if the fuel pump is not producing enough pressure. If necessary, replace the fuel pump after using a fuel pressure gauge to measure the pressure in the fuel pump during routine operations. Also, ensure that the fuel lines are free of obstructions and debris.

An unreliable ignition switch is another potential root cause of this problem. The engine may stall if the switch does not supply enough electricity to the fuel pump. Inspect the ignition switch and, if necessary, replace it. It costs $49.99

6. Abnormal Heat Under Seats and in the Cabin

The UForce often produces excessive heat in the cab and underneath the seats. It can make riding uncomfortable, particularly in hot weather. The increased heat has various potential causes, such as a broken fan or a clogged radiator.

To resolve this problem, you should first check the radiator and fan. Ensure that the fan is functioning properly and that the radiator has no blockages or debris. Replacing the fan or radiator might be necessary if broken or malfunctioning.

You can also put in heat shields or insulation to keep the heat out of the cab and from under the seats. If you have one fitted, a windshield will worsen the heat issue on hotter days. Keep it fully open and cracked, as this should improve airflow in the cab. The Heat shields cost between $22.45 and 942.86.

If you have side doors, there may be better solutions than taking them out, but it will much assist with the heat problem. In addition, adding a fan under the seat can improve airflow in the cabin, reducing the heat.
