1: Kawasaki FX921V Difficulty in Starting

One of Kawasaki FX921V engine problems is difficulty in starting. You may try hard again and again but it doesn’t seem to start. Even if it starts, it may end within a few seconds.

Most often, zero fuel in the tank can let this happen. Another reason is the air hole on the fuel tank cap is blocked with excessive dirt and debris.

A clogged fuel line is also responsible for blocking the fuel from reaching the engine.

Solution: Refill the Fuel Tank, Clean the Cap Hole and Fuel Line

Always give the fuel tank a check before starting the engine. If the tank has less fuel, refill it with fresh fuel. At the same time, clean the air hole on the tank cap.

Make some time and sit with the fuel lines to clean them thoroughly. Do this at least once or twice a month.

2: Kawasaki FX921V Losing Power Too Often

Is your Kawasaki FX921V losing power frequently?

When the crankcase is filled with excessive oil or is in need of oil, the engine fails to hold the power.

Another one is the bad oil pump or the oil filter that prevents the engine from getting required oil. Well, it can also be a sign of Kawasaki FX921V carburetor problems.

Solution: Adjust Oil Level, Change the Oil Pump and Oil Filter, Check the Carburetor

Checking the crankcase will tell you if the oil level is enough or not. Put as much as needed and not more or less. As for the bad oil pump and oil filter, changing them is the wise move.

For better protection, go through the carburetor and observe if it has any issues. Take no time in taking measures if there is any.

3: Kawasaki FX921V Imbalanced Performance

A condition can arrive that the performance of the Kawasaki FX921V is not balanced. In other words, it runs well for a while and then the performance deteriorates or increases the speed.

The culprit of it can be a faulty spark plug creating an imbalanced amount of sparks. Another one is the carburetor in need of adjustment or adjusted in a wrong way.

Solution: Replace the Spark Plug, Adjust the Carburetor

Kawasaki FX921V troubleshooting is a must to get rid of this trouble. Reach the spark plug to see if it is alright or not. If not, avoid delaying in installing a new one.

Kawasaki FX921V carburetor adjustment is essential to let it run well. The user manual will guide you to adjust it accurately.

4: Kawasaki FX921V Backfiring of Engine

The backfiring of the Kawasaki FX921V engine is a common issue when it undergoes heavy-load or excessive pressure. It can turn into a severe situation for the engine.

A major cause behind it is the inlet valve and ignition coil are not in good health. A leaked head gasket can let it happen, too. All these play together or particularly in inviting the backfiring.

Solution: Reduce Extra Load, Replace Inlet Valve, Ignition Coil or Head Gasket

I always mention that you should put as much pressure as the engine can bear. Be cautious to maintain the load.

As for the bad inlet valve, ignition coil or the head gasket, there is no way left than replacing them. Gladly, they don’t cost much.

5: Kawasaki FX921V Malfunctioning at High Speed

At some point, anyone will increase the speed of the Kawasaki FX921V to complete the task in time. But, you may experience the engine is not functioning as regularly at high speed, which is truly concerning.

The root cause behind it is a simple mistake of the user. A dirty fuel filter and fuel line and their clogged condition is responsible for causing it.

Solution: Clean the Fuel Line and Fuel Filter

Keeping the components clean that get in direct touch with fuel has no other way. If you fail to ensure that, such conditions can come up frequently.

So, after discovering the clogged units, clean them soon in a proper manner. I prefer purifying them twice a month.
