Ok. A fellow named Motorcycle Dr recommended low range, unless running it fast on a street. I think his reasoning had to do with lubing the wet clutch. Since I normally run it under 20 mph on mostly farm fields, I normally run it in Low range. If I go out on the gravel road, where I’m going 30-35 mph, I put it in high. A friend had a 700 massimo (Hisun). He burned up his wet clutch in under 100 hours. He ran it hard, and most of the time in high range. I don’t know the truth, still learning. Don’t want to have to fix mine, I prefer using it! 😀
