Took the injectors out. It took about a minute. The intake was also a snap. VST was very dirty inside, black deposits of crud on the bottom of the can. Screen type filter was a mess. Buying a new filter and sending the injectors off. Yamaha shop told me that there were no screens avail. for these injectors??? Same guys that want to clean the injectors by backflushing in an ultrasonic bath, I do not believe they have before and after flow rates like RX or Brucato.. Thanks again for the tips.
