Kawasaki KFX 700 Problems 

Most of the problems discussed here are common to the 2004 model year. Other model years rarely display problems. So, these are very reliable machines nonetheless. 

Common Problems of Kawasaki KFX 700

1. Mechanical Problems

Stock tie rods, tires, shocks, and the frame near the front “spar” area all wobble with the ’04 KFX 700 model.

Also, the steering hoop, swingarm bearings, intake valves, rocker arm shafts, and tail light all can have issues. 

The steering hoop bends easily when rolled. And there will be cracks/rust in the factory powder coat on the hoop itself.


These issues can be solved by replacing the problematic parts with aftermarket ones. 

TireReviews recommend replacing the tie rods and tie rod ends, replacing tires with aftermarket tires, replacing shocks with aftermarket shocks, and swingarm bearings with aftermarket bearings for example.

Although replacing tie rods and the ends may damage the stock frame. Either way, one will go bad. 

2. Overheating Problems

Some KFX 700s may provide you with overheating or cooling system problems. This can cause the engine to fail.


Check the coolant level and quality. Low or dirty coolant can cause overheating. If the coolant level and quality are good, the radiator or water pump may need to be replaced.

If there is even a little bit of mud in the radiator, it will overheat. So, always keep it clean. 

3. Electrical Problems

In some models of this ATV battery drain or ignition or lighting system issues are quite common. No dash lights problems are also pretty common. 


If the battery is good and fully charged, then you have a bad connection somewhere. Check the battery voltage, connections, and fuses. 

If the battery, connections, and fuses are fine, replace the faulty electrical component or repair the electrical system.

4. Starting Problems

When you crank the KFX 700 for a while, especially a ’04 model, it idles poorly.  Eventually, the starter would just spin.

When you take the side cover off, you may notice metal teeth missing from the starter gear. This easily causes the idling problem. 


Replace the stator and the starter gear. Also, you could have possibly not seated the flywheel or starter gear all the way when putting it back in. So make sure you do that. 

Check the battery voltage and connections. If the battery and connections are fine, the starter motor may need to be replaced.

5. Misfire/Backfire Problems

At idle, and through low RPM, it often misfires. But with the air box open, it may sound like a backfire. Especially through the carburetor from the cylinder.


The misfire may be happening due to a loose plug wire. It could also be a vacuum leak or bad valves. A common cause of misfires in the KFX 700 is a dirty or faulty spark plug.

Replace the spark plugs with new ones.

Additionally, clean or replace the air filter. Finally, check and fix any loose or damaged electrical connections.
