Common CFMoto UFORCE 600 Problems

Here we outline the most reported CFMoto UFORCE 600 problems based on owner experiences. We cover symptoms, causes, and solutions to get your UFORCE back on the trails.

1. Fuel Pump Failure

One of the most frustrating CFMoto UFORCE 600 problems is fuel pump failure. Symptoms of a bad fuel pump include:

  • Engine not starting or immediately dying after starting
  • Sputtering, stalling or loss of power while riding
  • Long cranking before engine starts

The fuel pump pushes gasoline from the tank to injectors. When it fails, the engine can’t get the fuel it needs to run properly.

What causes fuel pump failure? On the UFORCE 600, it seems the pumps themselves are prone to premature wear and electrical issues. Fuel contamination like dirt or varnish can also seize up the pump internals over time.

Diagnosing the problem involves first verifying fuel pressure coming from the pump. There should be around 40 psi. No pressure indicates pump failure. Also check for power getting to the pump when the key is on.

Replacing the fuel pump and filter is the fix in most cases. For access, you’ll need to remove the bed cargo box. Refer to a repair manual for detailed steps. Be sure to clean any fuel contamination from the tank when installing the new pump.

2. Torn CV Boots

The constant velocity (CV) joints on the UFORCE 600 front and rear drive axles are vulnerable to torn CV boots. These rubber boots keep dirt and grit out of the joints. When torn, contaminants wear down the joint leading to accelerated failure.

Symptoms of a damaged CV boot include:

  • Clicking or popping sounds when turning
  • Excess play felt in the axles
  • Grease splattered on inside of wheels
  • Visible tear or rip in rubber boot

Inspect the inner and outer CV boots closely for any cracks or holes. Also look for excessive grease splatter around the rims indicating leaks. Catch tears early before major joint damage occurs.

Replacing torn CV boots is recommended to prevent further contamination. The joint itself may need replacing if too worn. Take care to thoroughly clean joints and repack with fresh grease when installing new boots.

3. Overheating Problems

Another issue reported by CFMoto UFORCE 600 owners is overheating while riding or idling. Symptoms of overheating include:

  • High engine temperature warning light
  • Steam or coolant spraying from radiator
  • Loss of power as engine computer limits output
  • Sweet, odd smelling exhaust

When engine temperatures rise too high, it risks head gasket failure and other damage. What causes overheating on the UFORCE 600? Here are some common culprits:

  • Low coolant – Check radiator and overflow tank levels
  • Leaking hoses, gaskets, or water pump seals – Inspect for leaks
  • Defective radiator cap unable to hold pressure
  • Plugged radiator – Clean fins carefully
  • Stuck thermostat not opening – Test and replace
  • Cooling fan failure – Test fan operation

Start diagnosis by checking coolant level and inspecting the cooling system for leaks. Flush contaminated coolant and refill with a 50/50 antifreeze mix. Replace any defective cooling components like the thermostat or hoses. Keep radiator fins cleaned.

Providing the engine proper cooling will prevent harmful overheating conditions. Take action at the first sign of rising temperatures.

4. Premature Battery Failure

Some CFMoto owners report batteries dying prematurely, sometimes within months of purchasing. Symptoms of a worn out or defective battery include:

  • Dimming headlights when idling
  • Slow cranking or clicking sound when turning key
  • Battery gauge showing low charge
  • Eventual failure to start the engine

Why do some UFORCE 600 batteries fail so quickly? The OEM batteries may not handle vibration well or are undersized. Upgrading to an absorbed glass mat (AGM) battery adds resilience.

Test battery voltage – it should be 12.6-12.8V with engine off. If low, charge fully and retest. Clean corroded battery connections. If it still discharges quickly, replacement is needed. When installing a new battery, avoid overtightening terminals.

Also have the charging system inspected – a defective stator or voltage regulator can fry new batteries in short order. Maintaining good batteries is key for reliable starting.

5. Engine Misfires

Engine misfires cause a loss of power or uneven surging feeling when accelerating. Misfires occur when fuel isn’t igniting properly in one or more cylinders.

On the UFORCE 600, common misfire causes include:

  • Fouled or dirty spark plugs
  • Malfunctioning fuel injector
  • Loss of compression in cylinder
  • Damaged ignition coil

Start diagnosis by inspecting the spark plugs – look for wetness or black carbon deposits indicating a rich fuel mixture. Replace plugs if fouled or over 10,000 miles old.

Next, check fuel injectors using resistance tests and atomization patterns. Replace any injectors not performing as expected.

An engine compression test can pinpoint compression loss related to piston ring, valve, or head gasket issues. Compare readings across cylinders – low cylinders are suspects.

While not typical, damaged ignition coils can prevent proper sparking. Swap coils between cylinders to isolate bad coils.

Addressing misfires promptly will restore lost performance and prevent further engine damage from detonation or overheating.

6. Other Issues

While the above are the most prevalent CFMoto UFORCE 600 problems, here are some other issues reported:

  • Leaking differentials – Gear oil leaks indicate worn axle seals. Reseal differentials to prevent contamination.
  • Faulty throttle position sensor – Check and replace TPS if throttle response is erratic or stalling occurs.
  • Slipping drive belt – Belt wear causes loss of CVT engagement. Replace worn belt. Check clutch tuning.
  • Bad wheel bearings – Inspect for play and noise in wheel hubs. Replace faulty bearings before they seize.
  • Electrical gremlins – Corroded grounds, loose connections, or sensor failures can cause hard-to-diagnose electrical issues. Methodically test circuits and components.

While no machine is problem-free, paying attention to potential trouble spots on the UFORCE 600 can help catch issues early. Proper care and maintenance makes a big difference in longevity and avoiding breakdowns.
