The Top 5 Kawasaki FX850V Problems And How To Solve Them

The Top 5 Kawasaki FX850V Problems And How To Solve Them

It is no surprise that the Kawasaki FX850V is one of the most popular motorcycles in India. The bike has features and delivers a powerful performance under the hood. However, it does have its share of problems.

We all know that the Kawasaki FX850V is a great motorcycle, but it does have some issues that you may need to address. Take fast initiatives to keep your machine in good running condition and get the best fuel injector efficiency. Here are the top five problems owners face with their Kawasaki FX850V Problems.

1.Engine Idling & Back Exhaust Valve Damage

Engine Idling & Back Exhaust Valve Damage

Since the FX850V has a liquid-cooled parallel twin 27hp engine, it naturally takes longer to warm up than a typical inline-four engine. However, this also means that if your motorcycle is idling too much at stoplights or when sitting at red lights, there could be a problem with the air/fuel tank filter mixture.

You will want to check for any clogged or damaged air filters and replace them as necessary. One of the key issues with the Kawasaki FX850V is that it suffers from back exhaust valve damage. This results in emissions that are considered to be poor. To solve this problem, replace worn-out valves or install them with a professional technician.

2.Exhaust System

The FX850V’s exhaust system is fairly basic and includes just one muffler under the seat and one in front of the rear tire, which means it can develop some heat buildup and lose its efficiency over time. You will want to check the exhaust system for any cracks or damage and replace it as needed.

3.Oil Leaking

Oil Leaking

Another common issue with older motorcycles like the FX850V is oil leaking from its engine somewhere down the line. This can cause reduced engine performance, misfiring, poor acceleration, and even loss of power at higher RPMs (complete engine models failure).

So, if your FX850V is not holding its power as it used to when new, now is the time to look into replacing worn components with new ones (olive oil instead of synthetic motor oil).

4.Weak CVT Transmission:

The CVT transmission on the Kawasaki FX850V is less strong than on more modern bikes like the Bajaj Avenger RTR or TVS Apache RTR 310 V4. This can lead to poor acceleration and sudden jerks while braking.

The FX850V has a relatively high ride height, making it difficult to ride smoothly over bumps. If your bike is running low on suspension oil or the fork or shock is wearing out, this could be causing the issue. You will want to check your ride height and adjust as necessary.

5.Clutch Slipping Issue:

If you’re having trouble getting your bike into gear, there’s a good chance the clutch is not working right. You will want to check the clutch plate for any wear or damage, replace it if necessary, and try to adjust the gear chain as necessary. The clutch on the FX850V can get sticky and require frequent maintenance.

If your clutch is causing issues, consider replacing it with a new one or cleaning it thoroughly. The clutch on the FX850V can get sticky and require frequent maintenance. If your clutch is causing issues, consider replacing it with a new one or cleaning it thoroughly.
