100ml synthetic 2 stroke to a gallon of juice n you should be fine. The 175 I had was a lovely wee bike to ride, not much power mind but that meant I didn’t spin too much in the sections ?? Had no problems except for a seized swing arm pivot which I discovered when I tried to remove it for greasing. Find your self some easy sections and practice on them and you will enjoy the bike. All the best with it .
