If you want to buy a new lawnmower, you need to know about the Kawasaki FX730V. This is one of the best riding mowers on the market. It has many features that make it stand out from all others. However, before buying it, you should be aware of some negative aspects of this mower.

All Common Problems Kawasaki Fx730v

Here are some of the problems of this machine:

Kawasaki Fx730v Problems - Troubleshooting For All Users

Steering Problems

The Kawasaki FX730V has a problem with its steering. The steering needs to be better with other models in its class and may get stuck on uneven ground or slopes. This can be quite dangerous when trying to maneuver around objects like trees or bushes while driving your lawnmower around your yard.

Fuel Problems

The Kawasaki Fx730v is not a very fuel-efficient lawn mower. It uses a lot of gas and does not have as much power as other models today, such as John Deere or Toro mowers, which have much more powerful motors than this one when running at full speed while cutting grass. 


Deafening Problems

Another problem with this model is that it is deafening when compared with other models on the market today, such as John Deere or Toro mowers, which have much quieter motors than this one does when running at full speed when cutting grass. This makes it difficult for people living in neighborhoods where noise pollution is against local laws. 

Battery Problems

The battery of your Kawasaki Fx730v is a vital component that enables the vehicle to start. Battery draining fast is one of the most common issues that Kawasaki Fx730v drivers face. This issue can be caused due to a fault battery or electrical system. If the battery is not working properly, you may have to replace it as soon as possible. The following is the problems that you may encounter with your Kawasaki Fx730v battery:

Battery Problems

Battery Draining Fast

If the battery has loose connections, then it would enable the battery to drain very quickly. You can check the connections by disconnecting them and reconnecting them back again. If they are still not working properly, you should get them checked by a professional mechanic or replace them with new ones.

Vibration Problems

This model also tends to vibrate a lot while it is being used, and this can be very uncomfortable for some people, especially if they are using it for more than just a few minutes at a time. The vibration causes a lot of stress on the operator’s body and can cause them to get tired very quickly while using this machine.

Clicking Noise From Engine

If your Kawasaki Fx730v makes a clicking noise when you start it up, there could be something wrong with its engine. The most common cause for this problem is worn-out spark plugs which need to be replaced immediately.

Is The Kawasaki Fx730 A Problem-Plagued Engine?

The Kawasaki Fx730 is a 4-cycle, overhead valve, 573cc V-twin engine that produces 32 horsepower at 6500 rpm and 27 pound-feet of torque at 5000 rpm.

Is The Kawasaki Fx730 A Problem-Plagued Engine

  1. Kawasaki FX730V Engines Might Leak

Kawasaki FX730V engines may leak oil around the camshaft bearing. This is caused by a poor seal between the cam and its bearing race.

The problem is diagnosed by checking for oil leaks in the engine. If there are no leaks, the engine should be replaced because it will leak oil after some time.

The problem can be corrected by installing a new camshaft and cam follower seal. This repair should be performed at an authorized Kawasaki dealer because special tools are required to remove and install the camshaft.

  1. Kawasaki FX730V Engines Overheat

One of the most common problems with these engines is overheating. If you notice that your engine is often overheating or if it seems to run hot even when it’s not being used, you may have a problem with the cooling system on your vehicle. You can check the thermostat and ensure it’s working properly and not stuck in place by rust or other debris. Another thing that you can do is check for leaks and make sure that nothing is blocking the radiator from working properly.

  1. Loose Bolts Or Screws

Another problem with these engines is loose bolts or screws that hold things together. Suppose one of these parts becomes loose or falls out. In that case, it can cause serious damage to other parts inside of your engine and cause problems with performance when it starts up again after being shut off for a while without any maintenance work being performed on it first!

  1. Several Battery Issues

The FX730 engine has several problems that can cause it to fail prematurely. These include worn valve guides, excessive carbon buildup on the piston heads, weak exhaust gaskets, and leaking intake gaskets.

  1. Carbon Buildup On The Piston Heads

The most common problem with this engine is excessive carbon buildup on the piston heads. This occurs when oil is not changed regularly or if too much oil leaks onto the hot exhaust valve area. The excess oil causes carbon buildup on both sides of each piston head where they meet their respective connecting rods. When this happens, higher temperatures are generated inside the cylinders, increasing friction between pistons and cylinder walls and between rings and cylinder walls. This leads to increased gas emissions from your motorcycle’s exhaust pipe which can negatively affect fuel economy and performance while riding.

  1. Cracked Intake Manifold Gasket

Another common problem with these engines is a cracked intake manifold gasket. This usually occurs because Kawasaki uses an inferior gasket material that does not withstand high temperatures well. As a result, the gasket will fail prematurely, causing a loss of coolant in your engine’s combustion chamber, which then causes it to overheat and seize up.

The other common problem with the FX730V engine is a faulty ignition coil. If you notice that when you turn on your bike’s ignition switch, it takes longer than usual for the mower to start up, or if it seems like your bike isn’t producing enough power, then it’s likely that one of your ignition coils may not be working properly.

  1. Kawasaki Fx730v Surging

The Kawasaki Fx730v mower Surging problem is quite common. A lean condition causes the surging.

This can be caused by one or more of the following:

  • Blockage in the fuel supply line
  • Bad gas
  • Bad spark plug.
  • Dirty/faulty carburetor.

The following tips can help you troubleshoot the problem:

  1. Check the fuel filter and replace it if necessary (see your owner’s manual). For example, some mowers have two filters – one easily accessible under the hood and another in a hard-to-get-to location inside the carburetor housing.
  2. Clean or replace your spark plug (see your owner’s manual).
  3. Clean or replace your air filter.

Kawasaki Fx730v Starter Problems

The Kawasaki Fx730v mower is great, but it has some problems that may need to be addressed. For example, the starter can have problems that may require the replacement of the starter assembly.

If your Kawasaki mower will not start and you have ruled out other issues, such as a dead battery or low fuel level, your issue may be with the starter assembly itself. You can check this by following these steps:

  • Ensure all fuel lines are clear from debris and that you have fresh gasoline in your tank. If there is no start after this step, move on to step 2.
  • Check for a spark at the spark plug wire by grounding one end of a jumper cable on metal and touching the other end against the base of the spark plug wire. If there is no spark here, then move on to step 3.
  • Disconnect the spark plug wire from its connection near the carburetor and ground it against its mounting bracket (see photo above). Again check for a spark here. If there was none in steps 2 or 4, you need a new starter assembly.

Other Kawasaki Fx730v Starter Problems

  • Fuel Valve Sticking

Make sure that the fuel valve is installed properly. If it is not, remove it and reinstall it in its original location by aligning it with the notch provided on the body of the carburetor. Then, ensure a tight connection between its body and the mounting bracket.

  • Fuel Pump Leaking

Inspect for any obvious signs of leaks related to the fuel pump. If there are none, you should check if your carburetor has been changed at some point or if there is a problem with a part inside your carburetor (such as a faulty diaphragm). If there are no leaks or problems inside your carburetor, you will need to replace yours with a new one or repair it with parts available at an auto parts store or through an online dealer like Amazon.

Kawasaki Fx730v Carburetor Problems

Kawasaki Fx730v mower carburetor problems can be common for this model. The carburetor is the part that mixes gas and air before sending it to the engine. It can also be called a carburetor, a throttle body, or a choke plate.

The Kawasaki Fx730v mower carburetor has been known to have issues with leaking fuel from the float bowl and float needle valve assembly. A worn-out gasket between the float bowl and the upper housing cover causes this problem. When this gasket wears out, it causes fuel to leak from the float bowl into your lawnmower’s engine compartment. This can lead to damage in other areas as well, such as your spark plug wires or ignition coil wire insulators. 

Kawasaki Fx730v Carburetor Problems

Some models of Kawasaki Fx730v mowers also have an issue with their float needles breaking or becoming stuck in their float valves because they were not installed correctly at the factory when they were manufactured.

The Kawasaki Fx730v is a great mower for people who want to cut their lawns but don’t want to spend much money on a new machine. This model is very affordable and has some nice features that make it stand out from other similar models. However, like all other machines, some problems can also occur with this model.

How To Adjust The Carburetor Of Kawasaki Fx730v?

The carburetor on this mower has been known by many names, including “choke” and “slow jet.” If they’re not properly adjusted, they can cause poor performance and fuel consumption problems. To adjust them, follow these steps:

Step 1: Remove the air filter cover or cover plate from your mower engine housing to expose its components; then remove any screws holding these components in place if necessary.

Step 2: Unscrew the three screws holding your choke plate, then remove the choke plate from inside your engine housing (it may have a small metal clip attached).

Step 3: Take out the screws holding the air filter housing in place, and remove them from the engine.

Step 4: Remove the two screws holding your throttle cable in place, then gently pull it free from its housing on top of your carburetor. You’ll need to disconnect the connector at this point.

Step 5: Unscrew each of the three screws holding your carburetor’s float bowl cover in place; then remove them, along with the cover itself, which may have a small metal clip attached.

Kawasaki FX730V Fuel Overconsumption

This is a common problem with the Kawasaki FX730V. It’s caused by low-quality fuel, which can cause the carburetor to float, stick, and flood the engine. The cure is to use a fuel additive like SeaFoam or Marvel Mystery Oil. These products are available at auto parts stores and will help clean out the carburetor. You can also try adding some STP Motor Treatment to your fuel tank but only use it once every two months because it contains alcohol and can damage your engine if used too often.

Kawasaki Fx730v Smokey Exhaust Problems

This is a common problem on many Kawasaki’s. The smoke is caused by oil getting into the combustion chambers and burning along with the fuel. This can happen for several reasons, but the most common is that the oil pump pickup screen is clogged up with debris from the crankcase. A second reason can be excessive blow-by from worn piston rings or valves not sealing properly against their seats. If you follow the instructions below, you should be able to clean out these screens in less than an hour.

Kawasaki Fx730v Smokey Exhaust Problems

Step 1: Start removing your air filter box cover and element. It’s held in place by two screws, so remove them and set them aside.

Step 2: Now remove the spark plug wires from their respective plugs by rotating them 90 degrees counterclockwise until they come off their plugs ultimately (this will allow you to see better when you pull out each plug). Once this has been done, look at your plugs and notice how dirty they are on top, which means there’s oil getting into your combustion chambers! If any of these plugs have white smoke, that’s another sign of too much oil in your engine.

Step 3: Once you’ve removed all 8 spark plugs, remove the old gaskets at the bottom of each cylinder head using a flathead screwdriver or other small tool. Then put the new gaskets on top of each cylinder head and push them down firmly until they’re properly seated against the engine block.

Step 4: Now put your new spark plug back into place by hand, tightening it down until it’s snug enough not to fall out but not too tight to cause damage to your threads (if it becomes loose later on, then tighten it a little more). Make sure not to over-tighten these spark plugs because if this happens, then it’ll cause damage to your threads and make them even weaker than before!

Kawasaki Fx730v Running Rough

The most common problem with this machine is that it may start running rough after running for about 10 minutes. The engine will run fine at first, but it starts running rough and stops working within minutes. A simple solution to this problem is to clean or replace the spark plug and see if that helps solve the issue; if not, check your gas tank for any clogging or rusting inside it, causing a blockage in the fuel line, which could be causing this issue.

Kawasaki Fx730v Transmission Problem

The Kawasaki Fx730v transmission is a 4-speed hydrostatic transmission with reverse gear. The reverse lever is located on the left side of the handlebars above the clutch lever.

Problem: When engaging reverse, the engine does not slow down, and there is no change in engine speed when depressing the throttle.

Solution: Inspect/replace the hydraulic control valve (HCRV) and check for damaged or broken wiring in the hydrostatic pump or control valve. If the wiring is damaged or broken, replace the wiring harness.

Are Kawasaki FX730V Problems a Deal Breaker?

Overall the Kawasaki Fx730 is a decent mower, but its problems are enough to send you running for a different model. It lacks power, and durability and noise levels are higher than most. While it has some unique features, like an easy-to-use storage system, premium feel controls, and a sound traction control system, its downside outweighs the good.
