Anyone know where I can find cheap replacement fuel injector parts for a 2001 RC51. Just had my injectors cleaned and the guy said he broke the black cover which attaches to the fuel rail, because the injectors were really plugged up. One side has the tiny holes that spray the fuel and the other has that little darn thing I can't seem to find anywhere. All the local shops want to sell me the whole injector for $120. Anyone have have any laying around???? The guy that cleaned them said they really aren't necessary, is that true???
