Problem – 1: Bad Carburetor

Maintaining fuel efficiency is crucial for optimal performance of your Suzuki Intruder 1400. The carburetor plays a significant role in supplying the engine with the air-fuel mixture through the intake valve of your bike. However, issues with the carburetor can arise, leading to decreased performance. Common issues include faulty fuel pump or fuel pump relay, which can affect fuel flow to the engine. Another potential problem is the cable or coils related to Motorcycle Technology, which can impact the combustion process and result in poor performance.

It is important to regularly check the fluid levels and ensure they are at the appropriate levels. Additionally, owners of the Suzuki Intruder 1400 may encounter battery charging issues, which can affect the bike’s overall performance. Many riders opt for aftermarket exhaust systems for their Suzuki Intruder 1400 to enhance both performance and sound.


Possible Solution:

If your Intruder experiences a faulty carburetor, you may notice a decrease in bike acceleration and a lingering gas tank odor when not riding the bike. An increase in fuel filter consumption could also indicate problems with the carburetor. Regular maintenance and addressing these common issues promptly will help ensure your Suzuki Intruder 1400 runs smoothly and efficiently. The carburetor goes bad for different reasons, as seen in the section above. So, let’s focus on fixing it.

  • You can start solving the issue by removing the carb and cleaning it. You can try cleaning the carburetor and air filter with compressed air, WD40, and an essential cleaning kit.
  • You may also replace the gasket, hose, and seals if any wear and tear is available. It happens if the motorcycle is too old and hasn’t been maintained for long.
  • In case of a blocked main carb jet, you should switch it, though it won’t be the best solution.
  • Lastly, you may try repositioning the idle screw to keep things going. As you tighten the screw, it should help the carburetor and its filter work properly.

Problem – 2: Clutch Slipping

A non-functional clutch may cause severe damage to you, your pillion, and your bike. You will face problems when you want to turn or halt the bike properly. Some symptoms of having a slipping clutch driveshaft issue are lagging, squeaking sound, stiff gear pedal, and refused clutch. The rear cylinder of the Suzuki Intruder 1400 may experience overheating issues.

If your bike cannot accelerate well, the clutch disks may lose friction on the bike wheels. Even a faulty clutch may create a strange sound when you put pressure on it.

Possible Solution

Using expert-recommended pro-grade bike oil for the Suzuki Intruder 1400 is highly recommended. The wiring diagram should be consulted to ensure correct throttle cable installation. If the plates become dry and the clutches slip after long storage, while glazing over a bit, it is advisable to visit an auto repair shop for further inspection. After changing the oil, it is important to check the clutch condition.

Another solution could be overfilling the oil to flood the clutch plates, draining the oil to the correct level. The poor performance of the Suzuki Intruder 1400 has been a major concern among owners, but with the help of highly-rated, verified experts and proper maintenance, these issues can be addressed. Changing the bike oil and fuels twice a year is recommended to ensure that the engine parts run properly without any wear and tear due to friction. Another solution can be overfilling the oil to flood the clutch plates. It will drain the oil to the correct level.

Problem – 3: Fuel Pump Difficulties

The Intruder 1400 has an active fuel pump to process fuel lines from the fuel tank to the carburetor. This pump employs the right oil pressure to flow sufficient fuel in that process. In this model, you can ride almost 100K miles with the same fuel pump. But it can go bad eventually. Some notable symptoms are bike surging, engine stalling, and squeaking noise from the engine. Also, your bike won’t perform as well as it should. The Suzuki Intruder 1400 has issues with its battery performance, specifically a bad battery.

Possible Solution

When you detect the actual reasons for a fuel pump problem, it’s time to fix it. The good news is you may fix the fuel pump difficulties by following these steps:

  • It would be best to start by checking the ignition coil.
  • Then, inspect the white wire connected to the fuel pump.
  • Next, consider an engine rebuild if necessary.
  • Additionally, check the clutch switch for any malfunctions.
  • Finally, ensure that you have a strong battery to avoid any weak battery issues.

If there is any fuel flow, you can think of another issue instead of the pump. Thus, you might need to inspect the fuel pump further. You can call the dealer to check out the fuel pump. They will fine-tune everything. Otherwise, a replacement of the fuel pump may be required.

Problem – 4: Stator Rectifier Or Regulator Problem

A stator rectifier or regulator has a great duty in an Intruder 1400 machine. It can regulate the voltage of a battery and charge by rectifying the AC into DC. One important thing you should know is that all batteries have DC electric flow (direct current).

When your favorite bike has any problem with its stator rectifier, it may lead to battery damage or a dead battery. Some identical notes of the stator rectifier problems are dimmed headlight, the bike won’t start, and no spark with the spark plug. Also, the bike’s battery may take longer to charge or lose charge soon.

Possible Solution

Check out the OEM-suggested stator rectifier for Suzuki Intruder 1400 on the market. Then, replace it with the existing, faulty one. You can get the starter button rectifier from Amazon or official Suzuki dealers. Various issues can arise with the Suzuki Intruder 1400, ranging from electrical and engine performance issues.

Ensure you choose the right startor rectifier according to your Suzuki Intruder 1400 manufacturing model year. Different engine types offer varying levels of performance and efficiency.

Problem – 5: Faulty Battery

Battery plays a vital role in starting the motorcycle. Also, the electrical parts of the bike function correctly for a healthy battery. A typical motorcycle battery has a lifespan of 2-4 years. But it can fail or die suddenly over time. 

When a battery starts failing, you will get a different riding experience. You will get multiple symptoms of a faulty battery, starting with physical deformation. For example, the bike may stall or won’t restart if the battery is dead. You will get inconsistent readings even if you test it with a multimeter.

Possible Solution

The battery may not be charged for faulty wire grounds. In that case, you should read the bike manual and try to fix the shorted-out wire (if available). Another solution can be checking the expiration date of the battery labeled on it. It will let you know when to replace the battery. 

Lastly, it would be best to justify the battery’s voltage level using a multimeter. Note the number of amps the meter draws when the engine is on. Otherwise, replace the battery. The HP Exhaust System on the Suzuki Intruder 1400 may experience performance issues.

To ensure a reliable fix, seek help from professional mechanics or authorized service centers with the expertise to handle Electrical issues and problems like defective alternators. They can provide genuine replacement parts and ensure long-lasting results.

Problem – 7: Starter Relay Failure

A bad starter relay solenoid is a common problem in the Suzuki Intruder 1400 motorbikes. Usually, this starter solenoid looks like a cube-shaped black electric device. When you turn the ignition switch key, it maintains a connection between the battery and the starter. So, it is vital to keep solenoids active and error-free. But it can get defects!

A faulty solenoid prevents the regular basic power flow from the bike’s battery to its starter. As a result, your bike will fail to start or become unresponsive often. Some notable symptoms can be no cranking or slow crank in the engine.

Possible Solution

You should clean the starter relay by disassembling it. Remove any dirt, moisture, or corrosion from it. Again, you should change this device if it has wear and tear, fragmentation, etc. Regular maintenance and inspection of the alternator can help detect problems before they cause starter relay failure. If a faulty alternator is found, it should be promptly repaired or replaced. Monitoring battery health, ensuring proper charging, using high-quality batteries, and checking for connection corrosion or damage can prevent starter relay failure. Although the Suzuki Intruder 1400 is reliable, it is not exempt from problems like starter relay failure.
