Good day to you all. As described above in the topic I have problems with my Kawasaki and don’t know any more. Out of the hose from the KWG ventilation engine oil comes out and that not very little and the engine oil foams easily. It is definitely not too much oil on it and the piston and cylinder have come new. I now ask myself the question where the oil comes from have had the cylinder down twice because I thought vllt a piston ring is not right but that was not the fa ll. Can’t say if everything was fine before the piston change because I bought the machine like this already. Has someone had something like this before or can you give me tips on what else it could be? MFG Basti.
