5 SUZUKI KING QUAD 400 Problems
Now we are going to discuss the major problems of Suzuki King Quad 400 that its owner face and also tell the best solution of these problems.
1. Suzuki King Quad 400 fuel injection or fuel pump problems
When the fuel injector in these ATV models malfunctions, becomes damaged or gets clogged, it can lead to various problems such as rough idling, difficulty starting, abnormal fuel consumption, or failed emissions.
This can be due to a problematic fuel injector including sudden rough engine operation, misfires in one or more cylinders, resulting in challenging engine starts, or significant power loss.
While these symptoms can also point to issues with other major components, users have confirmed experiencing some of these signs when their ATV’s fuel injector needed cleaning, adjustment, or replacement.
Solution: You can start by checking the fuel injector and see if it needs a replacement or not. Damaged fuel injectors can later grow into bigger problems. If the problem prevails, seek mechanical assistance as soon as possible. So by following these steps, you can easily get rid of Suzuki king quad 400 fuel pump problems.
2. Suzuki King Quad 400 Starting Problems
A number of Suzuki King Quad 400 owners have encountered difficulties with engine starting, even though their vehicles initially exhibited excellent cold-start performance. One particular King Quad 400 owner noted that his vehicle performed perfectly when cold.
However, they noticed a significant change in behavior after running the vehicle for a while and then leaving it idle for 5 to 10 minutes. During these instances, the vehicle struggled visibly to restart, to the extent that it seemed to drain the battery. Interestingly, if he allowed the vehicle’s engine to sit for more than 20 minutes, it would eventually start up without any issues.
Similarly, another owner of a 2016 King Quad 400 reported being unable to start the vehicle, despite having the ignition key and start switch in the correct position. They could hear the fuel pump whirring, and the fuel tank was also full.
These issues often stem from problems with spark plugs or fuel pump performance. Even if the filters become clogged, they can lead to engine starting failures.
Solution: It is important to clean the filters completely to remove grime buildup so that these can contribute to easy starting. Sometimes faulty spark plugs can also cause the same problem, therefore replacing them can prove to be effective. By following these steps, you can easily get rid of suzuki king quad 400 starter problems.
3. Rough Idling
Some King Quad 400 models, particularly the 2014 version, may exhibit a frustrating issue where users observe problems with fuses and may notice fuel leakage while the FI (Fuel Injection) light is illuminated. Initially, the vehicle might continue to operate for several days or even weeks, even with a few problematic fuses. During this time, the engine may start slowly and appear to idle normally.
Solution: You can fix the rough idling of your Suzuki King Quad 400 by checking the fuses and see if they are working at their finest or not. Also, sometimes if there is a leakage then it will cause rough idling. Therefore, make sure there is no internal leakage and fix it in time.
4. Transmission Challenges
Although transmission problems with the Quad 400 are relatively uncommon, a small group of users has experienced transmission issues with certain models.
One 2016 Quad ATV owner reported that after covering approximately 10,000 kilometers on their vehicle, they were driving along a dirt road when he suddenly heard a distressing grinding noise. Following this, the vehicle gradually lost its ability to transfer power to the wheels, even though the engine continued to rev.
In response, they shifted their vehicle into neutral and then back into high gear, which surprisingly resolved the issue temporarily, allowing him to ride another 100 kilometers under demanding conditions. However, the recurring loss of power delivery indicated a persistent problem.
Solution: In such situations, it is advisable to inspect the Continuously Variable Transmission (CVT) and perform a comprehensive service, which may involve repairing or replacing the belt. Another possible cause could be a damaged bearing in front of the wet clutch. Therefore, aiming for replacements in this case can better fix the problem.
5. Engine Stalling
Consumers may encounter frustrating instances of engine stalling or electrical component failures, resulting in a lack of power and intermittent, substantial power loss. There have been cases when Suzuki King Quad 400 owners repeatedly faced persistent issues in their Quad, which have gradually worsened over time. They also described a pattern where the vehicle would initially start and run smoothly, only to unexpectedly stall or cut out when idling at low speeds.
To pinpoint the root causes of such problems, there are several critical areas that require thorough inspection and investigation. It may be due to inadequate ground clearance around the battery or complications with the Throttle Position Sensor (TPS). Additionally, running a fuel system cleaner like Sea foam can help improve fuel flow.
Solution: Checking the battery’s condition, along with its connecting wires and terminals, is also essential. Furthermore, problems may arise if there isn’t a sufficient application of dielectric grease on all connections or if there are any exposed wires left unattended. Therefore, always try to properly lubricate the connections to achieve seamless transmission.
Conclusion
The Suzuki King Quad 400 is thoughtfully engineered with an exceptionally broad power band and boasts an impressive torque capacity, ensuring it provides ample power to accompany you through various challenges you may encounter along the way.
Nonetheless, despite the array of exceptional features that continue the Suzuki King Quad legacy, the Quad 400 is not without its drawbacks.
Hence, it’s possible to encounter some troubleshooting issues discussed earlier. Now you can easily rely on your ride for thrilling off roading adventures!
