Hi, maybe I can help you with a few things, I had a DL K6 that I put SV throttle cams and bodies with good results. do you know the real differences between the motors? It may be easier for you to maintain the DL electrical part than to adapt all the wiring. Keep in mind that even if you put an SV control unit, it will never work exactly as if it were an SV since the airbox is smaller and the EXHAUST manifolds are different, therefore you will have to reprogram CDI or mount powercommander to correct the differences. If you have any dida I will try to help you in what I can.
Just a note, the DL after 14 have the pin but do not use it, they do not have the sensor. I just read a French technical magazine that lists the differences between SV 03 and DL, according to this the lobe centers would be 108.5 107 in SV and 102 108 in DL, is that correct?
