I came into this bike knowing the maint costs/intervals and knowing that I was going to be doing it all. It isn't that bad, even with the miles I kick on. Definitely no voodoo. It is all hard numbers. I did extend the interval to 7,500mi because the motor finally settled in after it turn about 50k. Seriously. The testas are somewhat different animals, but I'd still expect to have a tight motor into the 20k region.
The first tool/parts buy is a bit pricey, but less than dropping trou at a shop just once. And, I came away with a better running bike because I was a bit anal setting things to the desmotimes specs. My bike was dealer maintained by the POs through the 18k service.
Now with ducatidiag out there, it was nearly free to see that the ECU and sensors were still all good. The ducatidiag belt app is my fav for setting tension, btw.
Like you, I tend to get bored over time. Not with this bike. I actually look forward to the wrenching and can't help tinkering.
Have a good one.
