Preload with my foot, then push the little red button.
The little red button is an ignition kill switch tied to the Power Commander. Once the bike shifts, reset the shift lever and get ready to push the little red button for the next gear. I avoid using this technique between first and second gear.
If you have a power commander, you can hook up any switch to it, and you can preset the ignition kill time duration, currently mine is set for 60ms (just over a half second...)
