You need to contact jim @ redline cycle service in skokie Illinois, you can also go to his web site @ redline cycle service.com. I just had my fuel injection system checked out by him. THEY ARE THE BEST!!! Very informative, And he has 1000g parts for sale! I had to buy a used fuel pump from him for 285 buck´s. OUCH! take care , Andy Moore.P.S.
