Ducati very special limited edition superbikes inherit a sexy term "Corse" to their model name : 1098 R Troy Bayliss Limited Edition or 1198R Corse Special Edition.
Some performance shops while describing their engine services often use a term "Corse specification". For instance here is what posted on ducashop.com:
"...When you get a street bike from Ducati it is assembled with very tight clearances so it is more likely to spin a rod bearing or wear other parts prematurely. Blueprinting will set the clearances closer to Corse specs as well as ideal cam timing..."
The question is what are the Corse Specs in a first place? Is information on this subject freely available? Are there any known online resources or some printed publications? When Ducshop says they set the clearances "closer" to Corse specs where do they get those specs numbers? And why do they set the clearances "closer to" and not "exact to" Corse specs?

unless they start to machine some stuff, bearings and shims only come in set increments and it may not be possible with the factory parts to bring it exactly into the tolerance range spec by the whoever comes up with the "corse" specs. When you blueprint an engine for racing the tolerance gets bumped up an extra 0 at the end usually cut in half.
All they are doing is blueprinting an engine and calling it by an italian name.
