Ducati Hypermotard 939 / Monster 797 / Hyperstrada Oil Breather Valve By CNC Racing.

This is breather valve Ducati Models. Easy Installation item that makes a vast difference in style and performance. It is machined from light alloy billet and then given an anodized surface finish.

It's different in a sense that it doesn't have a reed filter as the OEM version, allowing for a better combustion gas release at high intensity engine use.

Also this valve will help with Ducati engine 'blow-by', which is when combustion gases leak into the crank casedue to piston rings getting worn out, causing accelerated engine oil contamination.

This often is noticed on Ducatis with oil appearing in the airbox, that is when excessive 'blow-by' causes large amounts of engine oil to be forced through the crankcase ventilation system and into the airbox.

The reedless oil breather valve helps to resolve these issues by releasing large amounts of combustion gases.

However, if your bike does not have any one of these issues, and your riding is mostly done on road and not on track, we advise you to purchase a breather valve WITH a reed valve inside as the original Ducati version, as it would work best.
