hey man i actually have a 95 gsr with a skunk 2 manifold and it took me over a year and several hundred dollars to finally figure out what the hell was causing this hesitation and rough idle, keep your stock throttle cable bracket tighten it up it will work fine may rub your hood when its closed but the problem i figured out today was that like most i just bolted it on and missed the most important part of the directions which is disconnect the iab control solenoid valve, check valve, and remove vacuum tank. the iab control diaphragm will come off with the factory manifold. connect the fuel pressure regulator hose to new manifold as simple as that! so before you get a fuel pump,filter,02 sensor, and your valves adjusted make sure you check that

96 gsr same scenario remove intake air bypass check valve
