Wrong, the injectors 150hp are the 243 or 391, while those of the 170 DC are the 341, watched the t-inj, those ducati's are much more? fast and the DC also fits the pump plus the CP1H R70. I have to check those of the delta that times have, the only problem ? that are piezoelettrci, I don't know if you can mount on the 140cv.
