Hello together, I needed to buy a Suzuki GSX 550 EU, first it went on in between but now it doesn’t go on after I cleaned carburetor, have cleaned air filters, petrol filter is also clean, in the carburetor the petrol arrives but not in the combustion chamber, can someone tell me what I can do? Oh yes also the spark plugs work Spark is there. Does it possibly have to do with that not enough or no vacuum is available from the tank the carburetor? The petrol tap is also free. I’m new in the motorcycle area so I don’t know what else to do about it anymore.
