What You'll Learn
Symptoms of clogged fuel injectors
Performance Issues
Clogged fuel injectors can cause performance problems such as restricted fuel flow, rough idle, engine hesitation, and reduced engine power. The bike may run smoothly at high speeds (WOT), but experience issues at idle or low throttle, such as a lumpy idle, misfires, and spluttering. In some cases, the bike may stall or sputter when it gets low on fuel.
Fuel Efficiency and Emissions
Clogged fuel injectors can lead to poor fuel efficiency, resulting in decreased gas mileage. Additionally, they can contribute to increased emissions, which can impact the environmental impact of the vehicle.
Fuel Pump and Filter Issues
Clogged fuel injectors may be related to problems with the fuel pump or filter. In some cases, the filter gauze on the fuel pump can become clogged, leading to fuel starvation. Cleaning or replacing the fuel pump filter can sometimes resolve this issue.
Visible Clogging
In severe cases, the fuel injectors may be visibly clogged when inspected. This was the case for one GSXR owner who found that their injectors were "completely clogged" and required manual cleaning with carb cleaner.
It's important to note that the symptoms of clogged fuel injectors can vary depending on the specific model of GSXR and other factors such as fuel type and storage conditions. Running the bike, using fuel injector cleaners, or seeking professional cleaning services are some ways to address clogged fuel injectors and improve their performance.

Manual cleaning methods
There are several methods for manually cleaning the fuel injectors of a GSXR. One method is to use a product like Seafoam, PJ1 injector cleaner, or Chevron Techron Concentrate Plus, which can be run through the bike. It is recommended to use such products twice a year, once before putting the bike away for winter storage and once when taking it out. It is also important to run a few tanks through the bike after using a cleaner and before putting in a stabilizer for winter. However, some people prefer not to use chemicals, and one user reports that additives will only clean what is downstream of the injectors and will not remove tougher deposits.
Another method is to remove the injectors and clean them manually. This can be done by taking them to a specialty shop, which can be worth the money. Alternatively, they can be cleaned at home by removing the fuel tank, pulling out the fuel pump, and then removing the three nuts holding the wires to the base and the screw from each side of the pump. The top of the pump can then be pulled off, although there is a rubber o-ring inside that makes this process a little difficult. Once the pump is removed, the assembly can be split apart to flush out the internals, which may be brown and rusty.
A third method is to use an alligator clip and battery to open and close the injectors while spraying carb cleaner through them. This method may require multiple cans of cleaner, as it can be awkward to use. It is also important to be gentle when cleaning the injector screens, as it is easy to tear the filter's plastic housing.

Ultrasonic cleaning
If your GSXR fuel injectors are clogged, ultrasonic cleaning is a recommended method to clean them. Ultrasonic cleaning is a process where sound waves are used to remove contaminants from surfaces. This process can be very effective in cleaning fuel injectors as it can reach and clean all the small and intricate parts of the injector that other methods may not be able to access.
Before opting for ultrasonic cleaning, it is important to determine if your fuel injectors are indeed clogged and in need of cleaning. Some signs of clogged injectors include restricted fuel flow, rough idle, engine hesitation, reduced engine power, poor gas mileage, and increased emissions. If your GSXR is displaying any of these symptoms, it is likely that the fuel injectors are clogged and require cleaning.
It is worth noting that some GSXR owners have expressed concerns about the effectiveness of injector cleaners, stating that they may not be able to remove tougher deposits and could potentially make the situation worse. However, others have found success with injector cleaners, especially when used regularly as a maintenance measure.
If you decide to proceed with ultrasonic cleaning, it is recommended to have a professional service perform the task, as they will have the necessary equipment and expertise to ensure the job is done properly. Additionally, they should be able to test the injectors after cleaning to ensure they are functioning optimally.

Using fuel treatments
Fuel treatments are a popular method for cleaning fuel injectors in GSXRs. Some sources recommend using a fuel injector cleaner, such as Lucas Fuel Injection Cleaner, which can be purchased in small bottles and used regularly, around once a month or every 4-5 months. However, it is important to note that fuel injector cleaners may not be effective if the injectors are severely clogged, and they can sometimes make the situation worse.
One user recommends using Seafoam or a similar additive, although they note that it will only clean what's downstream of the injectors and won't remove tougher deposits. Another user suggests cleaning the injectors manually with petrol and used oil, which they claim will result in better conditions.
If you suspect that your fuel injectors are clogged, there are several symptoms you may notice. These can include restricted fuel flow, rough idle, engine hesitation, reduced engine power, poor gas mileage, and increased emissions. If you observe any of these issues, it is advisable to address the problem promptly to ensure the optimal performance of your GSXR.
Before attempting any fuel treatments or cleaning methods, it is essential to consult a professional or a trusted GSXR community forum to ensure that you are using the correct products and techniques for your specific model and situation. Additionally, it is worth noting that some GSXR owners have reported positive experiences with ultrasonic cleaning at EFI shops, which can be an effective method to consider if your fuel injectors are severely clogged.

Cleaning the fuel pump
Step 1: Identify the Problem
Before you begin, it's important to identify if your fuel pump or injectors are the source of the problem. Common symptoms of a faulty fuel pump include difficulty starting the engine, engine bogging or surging at high RPMs, and sputtering. If your bike is experiencing these issues, it's likely that the fuel pump requires cleaning or maintenance.
Step 2: Gather Your Tools and Materials
You will need a few tools and materials to complete the job. These include a few cans of carb cleaner, soft wire brushes, old toothbrushes, coarse thread screws, a few gallons of gas or water, and clear tubing (3/8" I.D.). You may also want a rubber o-ring if you're replacing the old one.
Step 3: Remove the Fuel Tank and Fuel Pump
Start by removing the fuel tank. The fuel pump might be stuck to the tank, but it will pop out with a gentle slide. Be careful not to damage any surrounding components.
Step 4: Disconnect the Wires and Separate the Pump
Once the fuel pump is accessible, remove the three nuts holding the wires to its base. Then, remove the screws from each side of the fuel pump. Carefully hold the top of the pump and separate it from the base. There may be a rubber o-ring inside that makes this step a little tricky, so take your time.
Step 5: Clean the Fuel Pump
Now it's time to clean the fuel pump. Use the carb cleaner to spray down the fuel pump, making sure to get into all the nooks and crannies. You can also try using an additive like Seafoam, but be aware that it will only clean what's downstream of the injectors and may not remove tougher deposits. If your fuel pump has a secondary filter, you can backflush it to clean it.
Step 6: Reassemble and Test
After cleaning, carefully reassemble the fuel pump and fuel tank, ensuring everything is secure and properly connected. Start the engine and observe its performance. If the issues persist, you may need to seek professional help or consider replacing the fuel pump.
Remember to perform this cleaning process regularly, ideally once or twice a year, to maintain optimal fuel system performance.
