what is the best fuel injector cleaner for harley davidsons?

I agree with the above post. Most people run the highest octane fuel they can get which should keep the injectors as clean as possible.
 
Most of that stuff does absolutely nothing. If you really want to try some though go with Lucas. As long as you are running good clean gas you shouldn't have any problems anyway.
 
I used used a product called Seafoam and it helped with the carb on my bike.IThey sell it at autozone and Advanced Auto.
