My Dorso is back at the shop. The bike died mid left-turn last week and the Urgent Service light came on when I restarted it. It did the same weird surge between 2500-3000rpm with no throttle input. Managed to limp it home and then trucked it to the shop a few days later. Still waiting for the call back on what went wrong, but it the symptoms were identical to the bad cylinder pressure sensor that I had replaced about 18mo ago. I told the shop back then to replace both since if one was failing the other was probably going out and they told me they did. That shop no longer services Apes, so I'm trying out a new dealer. Ugh. If this was mechanical I could fix it myself, but I can't diagnose error codes from the ECU, so I'm stuck with the shops. Not sure when I can get the bike back.
