It's a 1998 ZR600 fuel injected. It acts like a carbed engine. It will bogg out like it's not getting enough gas. We bypassed the throttle cutout last year so that isn't it. We also unhooked the kill swich to try it and it still does it. It will idle fine but then it will just bogg when you try to go. It will finally take off but when I stop again it does it all over again. I also took out the fuel pump to check the screens but they were fine also. Any ideas?
