How Do You Clean Your Motorcycle Fuel Injectors?
You need to know one thing about fuel, and that is that it can spoil pretty fast, as a matter of fact, in a couple of weeks. In my friend’s case, he hasn’t ridden his bike for a year and a half, and fuel left inside his fuel tank went bad. Gasoline is made out of volatile compounds which evaporate as time goes by and what remains is s gummy residue of the compound that stays. A worse scenario is if your gasoline had ethanol because what then happens is the moisture can form, which will create corrosion and rust in steel fuel tanks and other metal parts of the motorcycle fuel pump and fuel injectors.

With all these problems diagnosed, we need to know the answer: How do you clean these motorcycle fuel injectors? I have witnessed where some riders took their fuel injectors and threw them into a tank filled with fresh fuel in order to clean the mess that old, gunky fuel did, but to tell you right away, that is not the right way to deal with dirty fuel injectors, and no, you won’t clean them properly in that way.
With all the gunk and crude sediment in the fuel tank and lines, you need to be prepared that you will need to clean your fuel injectors. However, you don’t need to worry because as complicated and challenging as it may seem on the first, cleaning motorcycle fuel injectors is not complicated to perform. Quite the opposite, it is pretty easy, and we will show you how. Your fuel injectors can be cleaned with Motion Pro.
Step 1: Get to the Fuel Injectors
The first thing you need to do is get to your fuel injectors. Separate your battery before you start to remove anything from your motorcycle in order to get to your injectors. Some motorcycles need to have their airbox and tank removed. Then you need to pull the bank of throttle bodies to access both rails of fuel injectors.
Step 2: Disconnect the Fuel Injectors
Separate the injector connections, disconnect the hardware that holds the injectors in the bodies, and carefully take them out. Don’t tighten them too much because you could damage them, and your Motion Pro Fuel Injector Cleaner will have no sense.
Step 3: Connect the Fuel Injector to Motion Pro Fuel Injector Cleaner
Take the engine side of the fuel injector first and install it in one of the tool’s two ports. You need to tighten the injector so that the connector is turned to the outside of the tool. Be cautious not to overtighten the clamp because you may damage the injector and have more issues to deal with. O-ring needs to seal completely.
Step 4: Install the Connector
After doing so, take the connector that is suitable for your motorcycle make and model and install it on the injector and tool. Once you push the red button, the injector solenoid is opened by the tool’s internal 9-volt battery that lets you go through the injector with a cleaner.
Step 5: Clean the Fuel Injector
You need to loosen the red button and put it in an aerosol can tube of injector, carburetor cleaner, or brake cleaner. Carefully tighten the button, so the tube gets sealed to the tool. Take the cleaner, push the red button, and use a cleaner to spray through the fuel injector to clean the unit.
By doing so, you will remove any dirt or debris that has accumulated in your fuel injector. This time, you won’t notice any spray pattern, only the fluid leaking out.
Take off the first O-ring and put the fuel injector first on the tool fuel supply part. Turn the fuel injector to clean the nozzle from a different side.
Take the clamp one more time and use it to seal the fuel injector to the tool. Be careful not to overtighten the clamp and place the connector so that it is turned to the outside of the tool. Use the red knob, seal the tube with it, push the red button, and release the cleaner. At this moment, you should notice a similar spray pattern. If you don’t see it right away, leave it for a minute or two, so it soaks, and try it one more time. If you somehow still have a problem, clean it one more time.
You need to repeat the same process for every fuel injector, and after doing so, take every one of them and reinstall it back to your bike.
Note: You need to return the O-ring you previously removed, don’t forget that. Look at the O-rings you took off and inspect them to see if they are functional or need to be replaced. Make sure also to flush the fuel rails.
Step 6: Reinstall the Fuel Injectors
After you have done all the previous steps and cleaned your fuel connectors, you need to take them and reinstall them on your motorcycle. Make sure you return every piece to its proper spot, and if you have any difficulties doing so, take a motorcycle manual and consult it for better and more detailed information.
Note: Every motorcycle make, and model has its specifics, and although these steps can apply to most of the bikes if you don’t have any experience in this process, the best thing you can do is to take your motorcycle manual or if you don’t have a manual, write your motorcycle make and model online and look for its specifics. This should ease the process of cleaning your fuel injectors.
What Causes Fuel Injector Problems?
Problems with motorcycle fuel injectors can happen because of a couple of reasons. If you haven’t been on a ride for a decent period, let’s say for a couple of years, and you feel like now is the perfect time to enjoy that sunny day’s ride. So you decide to go for a ride but notice that your motorcycle has some issues. After some time, you figure out that it has something to do with the fuel injectors. After further analysis, you establish that your fuel injectors are plugged or fouled fuel injectors from old gunky fuel delivered across the fuel injection system after switching or charging your motorcycle battery.
What that means is that you need to clean your fuel injectors, and in this article, we will help you to do so.
