When looking down the throat of the carb to check the spray duration and slide, I am assuming the bike is running with the subframe and the muffler off, correct? If so, this wont screw up the valves like a car running without it's exhaust will it? Second, when BK says to stab the throttle he is refering to a quick full throttle twist, right? My spray only seems to last approximately 1 second! Everyone else I have talked to said their's lasted 3-4 seconds???? Am I doing something wrong?
