The stepper motor is just a convenient device that allows an automatic fast idle on start up which ramps down as the engine warms. It is convenient. It also helps maintain a throttle setting when idling in gear at slow speed. Example, when I let the clutch out without adding throttle, the stepper increases the throttle to help keep the engine at that throttle setting. I think it was @warp9.9 who posted those pics last summer showing the amount of influence the stepper has on the throttle plates without interfering with the throttle cables. I would try to keep it (stepper) in place rather than remove. I often start the bike up and let it run when cold to warm up as I check it over. Don't really feel like having to manually do what I paid Triumph to provide... To each their own.
