Not sure how that's relevant to a question with a Boolean answer. Just curious. There is a pretty good Shifterkart package already available (Halfords Staff). I started in karts and 40 years later returned to karts with my son. Played with an ICA but it seemed a little anemic compared to the shifter. We also had an ICA twin direct drive for a while, now that was a blast, but only classed for road racing.
