I need help. I have a 2002 ZR600 EFI that will idle fine and then will bog and die when the throttle is pinned. I hooked up a fuel pressure guage and it looses pressure when this happens. I checked all hoses in and out of tank and they are good, replaced fuel pump because it makes a cavitation noise when this happens, fuel tank is full. I also cleaned power valves and check cable adjustments, they are fine. So it is still making the noisy fuel pump noise and loosing fuel pressure. I have checked the voltage output while running and it is fine. Please, any help would be great. Thanks, Bryan.
