Thank you Cormanus, an illuminating thread that proofs I'm not the single one in this thankless situation of strong vibrations over 3500 rpm and knocking; sadly is worse, is a irreparable constructive mistake. I wonder how many owners admit freely they have this very serious problem, if they fix it somehow locally or if they where able to contact Honda Japan directly and find the solution for that(apart from selling it). I personally struggle for months to contact Honda Japan by mail but I haven't found the address anywhere or any specialist who can help me. I've already been at 5 independent experienced mechanics.
PS: I contact two Honda dealers locally, Honda Germany and UK... nobody came up with a solution in order to help me and totally silent in disclosing a direct connection to Honda Japan, very disappointing.
