Im a complete newbie with karts. I'm in the process of getting a yerfdog gx150 spiderbox up and running. It runs but not well. Even at that it is a little faster than I want right now for my 10 year old to drive around our few acre yard. Is there some way to slow it down to about 10mph for a while at least until she's more experienced? It would be nice if it could change the speed easily so my 20 year old nephew could go faster. Is there some kind of governor?
