I think they have problems with the ignition. There are several films on youtube, but they never ride against the big rocks, and if you listen to the sound of the engine ... it is not that snappy as the Beta's, or Sherco's. It will take some time for that, there are a lot of parameters to find out.
For the clubmen rider it will be enough, but they will compete at the top in the world championship, so they still have a lot of work todo.
