Just a quick question my friend has a 93 kaw ninja 600 zx i think thats the model. Over the weekend the plugs was changed and now all of a sudden it runs like **** takes off slow, dies when not giving it throttle, and doesnt sound good at all. I dont really know much about older bikes let alone a ninja. Does anyone know maybe a website where the wiring diagram maybe to look at the plug wires to make sure the ends are on the right plug for the firing order. Also any line that connects to the gas tank. Im just trying to go through anything that it could be. Thanks any info would help
