The problem is that the bike was imported so I don't have any record of what the previous owner did, even the workshop record that is supposed to be written in the book that comes with the bike was totally blank, so I don't even know how it was maintained...
I have to try to get some serial number from the ECU or some other identification to see if it is the stock model belonging to 2005.
But no worries it will be fixed one or the other way, we have winter running up now so I have lots of time to investigate and to make vice decisions...
The workshop also claimed that the map used in the bike was for an other exhaust pipe so that was the reason why they changed the map, but suppose that was just a bad excuse.
