When the engine has been running and then turned off the valve will reset when you next turn on the ignition.If you then do not start the bike it doesn't reset any more until it's been run.If you turned the engine off via the kill switch it would reset then and not when you next turn the key on. Can't help you with servo direction I'm afraid.
I think there are 2 threads going on here the OP who put the video up ( Markie)isn't the same is the other (tefer) who is having trouble with his exup as well.
