    I am answering to myself.....
    Today i visited a verry experienced mechanic. He was a Ducati dealer in the eighties and nineties. He received the first imported to France 851 from the factory at that time. So he knows verry well all the storry of the Desmoquattro. He is until now preparing alll kind of racing bikes.
    He says that my bike is running normaly and the "roughness" at 3000-4000 RPM is perfectly normal for the 851 in his original setting.
    Regards
    Laurent

    Hi Brad,
    According to your previous answer, I have ordered the 916 springs last month but one side is on back order in Germany (unknown delivery time).
    So that is still on my wishlist and will do the swap as soon as possible. ;-)
    Will keep you advised if any improvement.
    Regards
