Ducati Streetfighter 1098 Desmo Valve service

The DRILL crew and Team MCC (duc_doc) tear down one of the club member's Streetfighter 1098 for the valve clearance check and clutch inspection.

The elegant Desmodromic valve system, unique to Ducati, is an engineering marvel since there are no valve springs like all traditional engines have. Instead each valve has two cams, one to open and one to close, rather than using a strong spring to close the valve. This means there’s less mechanical resistance in the Desmo system since the cams don’t have to overcome the pressure of valve springs. The only springs you might see in there are the ones that simply keep the rocker arms stable, but you can literally push those with a finger and they don’t have anything to do with closing the valves. This is an older 1098 V-twin, but the Desmo system is one of the reasons the new V4R can rev higher than any production 999cc in history since the engine can spin easier.
