Stromer, you are right, but the things here in Italy goes different about the two year warranty.
I also know how most dealer work...you pays for things they don't clear/change.
In my past CBR 954 RR, bought with 18000 km from dear my friend, air filter was never changed but my friend payed for it (he show me the paper).
I'm sorry if my language is very bad but I know what you mean...believe me.
Every service they made I re-check all because I don't thrust in what service do...or better...what they say to do.
