Buell and Sportster Fuel Injector Maintenance
21-9-2013 - It is very important to Clean your Buell, XR1200 and Sportster Injectors from time to time. It is also depending on what gas you get for your bike at what gas station, and in what country you live.
We use much more Ethanol in our gasolines then before. Here are some fact's about what Ethanol is doing with our Buell's or XR1200 or Sportster. In every country the amount of Ethanol can vary. We bought a Fuel injector test and clean machine to do this service In-House.
You can send us your injectors, and we ship them back in 1-2 days. You need to purchase the product HERE:
ETHANOL PROBLEMS
We bought a Nice Injector flow tester and ultrasonic cleaner. We are very happy we can offer this in-house service specially for Buell's and Sportster cause that is the only thing we do.
We offer the service to flow match your injectors and to clean them so you are 200% sure the data in The ECM that is used to get your the right amount of fuel, comes out in your cylinderhead and you are not running a lean mixture on your Buell.
Here is a picture that shows the injectors when not cleaned and there behaviour. Look at the glasses and see how different the volume is.
Here you can see how it needs to look like, all are the same volume.
Here is another picture to get a idea what can happen in your cylinder head when you drive with dirty injectors.
Here you can see a dirty injector
And here you can see a clean injector
Other than it “feels” if the engine runs better there is just no way to verify or confirm that the money spent on fuel injector cleaners was worth it because visual inspection of fuel injector spray patterns and flow rates are not possible.
leaning fuel injectors by removing them from the engine and then proceed with a process of visual inspection, ultrasonic cleaning and actual flow testing for spray patterns and volume is the only accurate, guaranteed, reliable, and sure way to confirm a clean fuel injector and that your fuel injectors are doing their job. Anything ells is only guess work.
This is what you see of the injector cleaning process if the injectors are cleaned on the engine
....................................................ABSOLUTELY NOTHING!............................................................
And Here is something for our gear heads.
Proper fuel injector atomization cannot be determined.
Correct fuel injector spray pattern and distribution cannot be determined.
Damaged pintle caps, bad, cracked or torn O-rings cannot be discovered.
It cannot be determined if the fuel injectors has leaking pintle, disc or ball valves.
It cannot be established if fuel delivery per pulsed cycle set is correct
It cannot be established if fuel delivery for the fuel injector set is equal.
Injector Cleaner can only clean what it touches!
Liquid in its natural state or under pressure will always follow the easiest path. It therefore becomes clear and understandable why some fuel injector cleaning methods such as fuel injector cleaning chemicals in the form of, fuel tank additives or fuel rail induced injector cleaners more often than not does not do a good job of cleaning the internal components of the fuel injectors.
Fuel injector cleaner in the form of chemicals cannot distinguish between the various components it touches and therefore will have a cleaning effect on everything it comes in contact with.
In theory this is supposed to be good but in practice this more often than not has the opposite effect. Grime and dirt loosened by the fuel injector cleaner from the various fuel system components such as the fuel tank, fuel lines and fuel rail are sent directly to the fuel injectors. Since the filter baskets inside the fuel injectors are only between 3 and 10 microns in size they become clogged very quickly. In some cases fuel rail induced injector cleaner will damage the filter baskets and allow for larger pieces of debris to enter the fuel injector. This can cause the pintle to become stuck or if the debris lodges itself on the pintle, ball or disc seat the injector will start to leak. Leaking fuel injectors is not only a fire hazard but can also cause engine damage.
Some of the products might even be harmful to expensive components such as catalytic converters, oxygen sensors and other components.
Other than it “feels” if the engine runs better there is just no way to verify or confirm that the money spent on fuel injector cleaners was worth it because visual inspection of fuel injector spray patterns and flow rates are not possible.
