I shimmed my valves and figured I'd make sure the servo was working. I've read somewhere in the forums that the servo cycles once when you first start the engine. Mine does that. After I let it warm up on the stand for about five minutes I'd blip the throttle and the servo would cycle and go back to the neutral position. Next I strapped the sled down good (cause I know it probably isn't a great idea to run the thing at 5 or 6 grand on the stand but I did it anyway). Is the servo supposed to stay in the open position because if I hold the throttle steady, at say 6000 rpm's, it cycles open then back to neutral. My ZR is carbed. It has a TPS sensor and a temp sensor.

My questions are, does the servo stay open or just pop the valves open and go back to neutral? And does the temp sensor effect the servo's operation as far as working differently when the engine is fully warmed up?

Thanks to all.
