As above gents. Just before my motor went in for a rebuild I ordered a crankcase breather for my hyper....turns out the 1100 crankcase breather is different from the evo sp. But, I had to wait to get the engine back to find out it didn't for so I can't return it. I'm assuming there are other models that will so, a I've got an unused one for sale and b can anyone point me to a compact aftermarket breather that will fit. Just for the info the 1100 one is about a quarter inch too small on the bore...
This is the one I've got... http://ducabike.com/ducatiparts/en/superbike-749-999/480-vso01-valvola-sfiato-olio.html
