Howdy again, y'all! I haven't posted here in forever, but I figured I could pick the brains of some of y'all for advice. My question concerns using a dirt bike engine in a 250R-based ATV. Specifically, what transmission ratios would work best given the following combinations in the attached table? What would be a good starting point for final drive ratios? The primary riding will be in the dunes and trails, with some trips into the woods every once in a while. I'm not interested in drag racing at all. Any reply would be greatly appreciated.
