I do believe that it travels up the plate later than it would be without the govenor kit. You might want to ask Piers but I think the lever (not sure that is the correct name but I'm sure you know what I am talking about) will be on a differnt spot on the cam plate at the same RPM. Everything will happen later. I think this is the key to the devlopment of the govenor kit to make it work with our exsisting cam plates but with some of them it takes a little tweeking.
