So to my problem Have a Kawasaki ZZR600 standing in my garage which has not been operating since last year. My landlord gave me this machine because he bought an R6. The problem is that the machine does not start. It is constantly on the org but it simply does not want to jump on. However, if I “put” petrol into the intake tract and the starter turns the machine up (6000U/min) – so again switched off because the engine is cold. I have fol gendes done on the machine: – The petrol line which leads to the carburettor checked–OK – vacuum line to the tank checked–OK – carburettor removed and these individually checked (carburettor needles & floats) are in order–OK – spark plugs replaced and when I’m already doing the ignition coils tested–OK – compression checked–OK . Oil changed–Check But I just can’t get the engine on. The starter turns and turns neither false ignition nor anything else happens : /. Today I pushed up and down the carburettor membrane from jux times and noticed that one (cylinder 2) does not build up “pressure”. So I removed and see a hole :/ But can it be that a membrane makes the machine do not make a mux? Has someone made the same experience and can help me =) I am technically gifted but I don’t want to take the engine apart now =)
