If you keep in the upper 1/3 of your RPM range (eg racing) then the AP doesn't do as much for you. In fact, it will add extra fuel, leaving you with a rather rich condition. That's why 400/426 racers would limit the duration to .3 seconds with the BK mod, and is probably why the YZ450s have a larger leak jet.
For the rest of us, those who frequent lower RPM ranges, the AP squirt is necessary, or we'll still bog, but this time from a momentary lack of fuel when we crack on the gas after the slide has been closed (slide closed, no vaccum; no vaccum, no fuel from jets). That's why .5 - 1 second duration is recommended for the rest of the mere mortal 400/426 riders, and why the WR450's have a smaller leak jet.
You can give it a try, but you'll find that stabbing the gas is still going to kill it. When I get back next week I'll give a larger leak jet a try.

that should do it and the tests are free.
