if you get digital io cable service (definitely here in the tri state ny area) there is a 15 minute segment on ducati valve adjustments from the pro italia shop in CA with a mechanic whose first name aludes me but his last name is french. probably very elemental to those experienced in these matters but it was pretty interesting because it helped me to understand a little as to how the engine works and what theses things called a valve and shims actually looks like!
