..I have had problems.. E4 model 2019 #68 -so very early built- at the beginning oil consumption was about 0.6liter/1000km caused by wrongly assembled oil rings on right cylinder, all end gaps was in same position. => New cylinder/piston replaced right side under warranty -2000km on clock that point. The whole work lasted four weeks; first set which Piaggio send to dealer was out of the manufacturing tolerances -too tight. All these tells poor quality control. Rear drive seals replaced, Recall work, no leak in my bike.
After that cylinder changing oil consumption was about 0.1l/1000km, acceptable for air cooled. Last July engine pushed oil in airbox without any warnings, ie I didn`t notice anything performance lost or so in normal riding. (36000km riden) Have to take old V11 to France/Italy tour...
When I opened the engine to found reason for high pressure inside the crankcase I found something unbeliavable: Both side compression rings end gaps measured 3-10mm!!? Top of the cylinders feelable step. Everything else was ok, no oil circuit problem. No leak over airfilter. The only explanation in my opinion is serious material failure or wrong material choices which don`t work together.
Now the sad part: Our importer replaced year ago -Piaggio Nordic in Sweden "take care" all Piaggio sales in Sweden, Norway and Finland where I live. My bike warranty was exceeded three moths but the consumer law here said that; "Items should last expected time" I have contacted my dealer here and asked new parts. After four month no answer... Problem is somewhere Sweden or Piaggio Italy. I`m disappointed how the Piaggio handle customers. I believe that my bike is like that gearbox without oil -bad individual mistake (and poor quality control) It seems that without large scale publicity you don`t get anything.
