The Kawasaki KLX 250 is the perfect dirt bike for off road travel. But its performance goes further than just that. This bike was built for both on-road and off-road riding. This model carries unmatched flexibility, amazing power, and highly reliable performance.
The adjustable front and rear suspensions on this lightweight bike make it a great fit for riders. Whatever your area, this bike won’t fail to deliver. However, all things being said, there are still some Kawasaki KLX250 problems you might run into. These are not caused by the model itself and are mutual in most dirt bikes. Let’s look at 5 of the most frequent issues you might encounter with a KLX250.
Common Kawasaki KLX250 Problems
1. The bike Won’t start
This is a common problem with the KLX250 and most other dirt bike models, for that matter. Sometimes no matter what you do, the bike is dead set on not starting. Now there are multiple possible motives and answers to this issue. You will have to take a thorough look at your bike to find the exact cause. The most common reasons are a dirty carburetor or bad gas. A messy carburetor problem is fairly easy to fix.
Sometimes, something as simple as strenuous the carb will solve this issue. If you do this and the problem perseveres, it’s time for a full cleaning. As for bad gas, swapping fuels might help. Many people believe that the fuel grade you select doesn’t make a difference. But this couldn’t be further from the truth. After all, the user manual comes with explicit commands about the appropriate fuel grade. For the KLX250, you should be using octane fuel rated 87 or higher. Other possible but common causes might contain a weak or dead battery and firmness or spouting hitches.
2. Clutch Problems
It would help if you had the clutch to shift gears. You also need it when you want to stop your bike without delaying when it’s not in gear. This is a very important apparatus, and you can’t do without it. However, sometimes the clutch can become faulty, which can also affect the engine’s functionality. The clutch uses resistance plates. The clutch springs create density, which makes the plates grip. When the pressure is unconfined, the friction plates slip. Both of these movements are vital for the well-functioning of the clutch mechanism. But as you may already know, whenever there are moving parts, you will ultimately run into some topics.
The most common snags on the KLX250 are either a dragging clutch or a slipping clutch. Both of these issues can be easily resolved by correcting the clutch cable. Make sure everything is appropriately in place. Sometimes, a slithering clutch can also be caused by worn out clutch plates, in which case you will have to look into substituting them. Different reasons for a dragging clutch embrace warped plates and jutting or gunked up plates due to old fuel build up.

3. The bike won’t Idle
Sometimes, you want to bring your bike to a halt without killing the engine. But when you have an idling problem, you might find that your motor abruptly stops. There are a few possible causes for this:
- Your idle screw might need some modification. Remember, the idle screw’s job is to control how much fuel reaches the engine when you are not moving the throttle. If the idle screw is set too low, the engine might not receive enough fuel to keep running when idle. This is also one of the main problems when cold starting a bike. But this is an easy fix. You have to find the screw and switch it to bring up the idle RPM.
- A dirty air filter can also affect the engine. The bike engine uses both fuel and air for ignition. But a dirty air filter makes it harder for the air to get where it’s supposed to. In this case, you might get a rich air to fuel mixture. Your bike might start smoking up, and you will end up with lower idle power. Frequently cleaning or swapping the air filter will get rid of this issue.
- Likewise, the fuel screw can also cause fuel problems. The screw can cause a too rich or too lean mixture. When the air to fuel mixture is too rich, the idle drops. The idle will rise when the mixture is too thin, but the engine might start knocking. Trace the fuel screw and adjust it little by little until you find the perfect middle ground where you get a high idle with a good throttle reply.
4. Stained Spur Plugs
Spark plugs are a very significant part of the ignition system. As the name proposes, spark plugs create a spark that you need to ignite the air fuel mixture in the engine. Without them, the engine won’t start. This is a less common issue on 4 stroke models like the KLX250, but it isn’t unheard of. In most cases, the cause of fouled spark plugs is rich jetting. When the engine obtains more fuel than it can burn, the rest of the fluid might seep through and onto the spark plugs. When the plugs get wet or dirty, they stop doing their job appropriately.
A clear suggestion of rich jetting is extreme smoking. If you notice black smoke coming out of the drainpipe. A dirty air filter can also foul up the spark plugs. When insufficient air reaches the engine, the excess unburned fuel creates a residue that can foul the spark plugs, limiting their ability to send the spark to fire up the engine.
5. Gas Leaks
Gas leaks are a problem for numerous details. They lead to fuel waste, and the leaking fuel can gunk up the engine and other gears. But most importantly, it’s risky to have a highly explosive liquid dribble out of the tank and somewhere where it shouldn’t be.
The most common problem areas for gas leaks are usually the fuel bowl, the fuel switch, the car drain screw, or the carb overflow. The most probable cause for this is a fractured washer. Wherever you have a seal, you might experience such issues. If the seal isn’t properly in place, or if there is a crack, fuel can seep through. A high float level can also lead to gas spilling out of the overflow tube.
