I'm an old Honda ATV rider. The Honda's have proven themselves over and over. I have never owned a ES model and have started looking to step up from my old 300 fourtrax to a foreman. Seems I can find some good deals on slightly used ones but when I call they all turn out to be an ES model which scare me a little. I have found that there is an aftermarket kit to convert an ES to S but question how well that really works and if the electronics are giving problem's would that not still mess up the instrumentation and neutral switch and so on? Any comments concerning this would be appreciated.
