Well it really depends on the setup and what box you are using. I prefer to start long and work my way down to a shorter delay until it misses a shift. (the less mis-shifts the better IMO). Most street bikes will be around 60 - 75 ms with an over the counter analog set-up. Now if you are real careful, use a digital kill and tweak the setup you can shorten the kill time up a bit. I'm at 33ms 1-2 shift, 2nd gear on is 31 ms. Could probably go a bit quicker but not wirth chewing up dogs.
