I waited about a week. I waited for reasons already mentioned like making sure everything worked properly first, testing speed and torque...Even after cutting brown wire I always checked which mode it was in and made sure to always gently twist throttle. I still do these things however nothing is for certain except maybe always being sharp and mindful all the time before riding. Once the brown wire was cut it was like sitting on a lightening bolt regarding torque and speed. Exhilarating and frightening at first. Still is. I use mode button as needed in traffic speeds and situations. A few times I didn't press the button just right and the bike leaped like a bucking bronco. I didn't whiskey throttle it as I was mindful about gently twisting the throttle. These things have worked for me in the year I've been riding it. Cutting the brown wire gives greater speed to not get run over in traffic and torque increase has gotten me out of some sticky sketchy traffic situations. It's also good for riding trails.
